Off-site search engine optimization
Off-site SEO, also known as off-site search engine technology, is named after the influence of external sites on the ranking of websites in search engines. These external factors are beyond the control of the website. The most useful and powerful external site factor is reverse link, which is what we call external link. Undoubtedly, external links play an important role in the search engine results page.
So how to generate high-quality reverse links?
1. High quality content
The best way to generate high-quality external links is to write high-quality content. The content of your website makes readers want to read it. You can exchange links with other websites, register a program that automatically generates links, and buy links from other websites.
2. Send an email to a website related to your content.
I don't advocate group email to other websites for link exchange, but I suggest that if you write a high-quality article on a topic and think it will interest other websites, send them a short and polite email to let them know that your article is valuable. Don't be embarrassed even if they don't have a link. You will find that if they click, it will generate direct traffic for the link, so that your website will get better scores in search engines.
3. Classification catalogue
Another way to generate backlinks is to submit your website to the classified directory. Many webmasters are convinced of the effect of this method. When starting a new website, the first step they do is to select the appropriate keywords around the classified directory and submit them to the links of related pages. There are many classified catalogues, most of which are free.
SEO in the station
Enrich website keywords
Adding new keywords to your article will help the search engine "spider" to crawl the article index, thus improving the quality of the website. But don't pile up too many keywords, consider "what kind of keywords will people search for when they find this article in a search engine?"
These keywords need to be mentioned frequently in your articles. You can follow the following methods:
Keywords should appear in the page title tag;
There are keywords in the URL, that is, some keywords can be put in the directory name and file name;
Including keywords in the link text of the webpage export link;
Display keywords in bold (try to do it at least once);
Mention this keyword in the tag (there has been a debate about how to use the head tag, but it is agreed that the effect of h 1 tag is better than that of h2, h3 and h4, and of course some web pages without the head tag also have high PR values);
The ALT tag of the picture can put keywords;
The whole article should contain keywords, but it is best to put them in the first sentence of the first paragraph;
Put keywords in meta tags.
It is suggested that the keyword density be between 5% and 20%.
Theme website
If your website is all about the same topic, then it may get a better ranking. For example, a website with one theme will rank higher than a website with multiple themes. Build a website with more than 200 pages, all on the same theme, and the ranking of this website will continue to improve, because your website is considered to be authoritative on this theme.
website design
Search engines prefer friendly web page structures, error-free codes and websites with clear navigation. Make sure your page is valid and visible in mainstream browsers. Search engines don't like too many Flash, iframes and javascript scripts, so keeping the website clean and tidy is also conducive to the search engine "spider" to climb the index of your website faster and more accurately.
Internal links of the website
The working way of search engine is to grab the information of web pages through the "spider" program, track what you have written, find web pages through the link addresses of web pages, and extract hyperlink addresses. Many SEO experts suggest that websites provide site maps, and it is best to have one or two deep links between each page on the website. The first step of the website is to ensure that the navigation contains table of contents pages, and each subpage has links to the home page and other important pages.
Regularly updated
The more frequently websites are updated, the more frequently search engine spiders crawl. This means that new articles on the website can appear in the index within days or even hours, instead of waiting for weeks. This is the best way for the website to benefit.
outbound link
Exporting links will improve the ranking of websites in search engines. Linking to other related websites in the article is useful for readers, and there are some anecdotal evidence to support this theory. Too many exported links will affect your website, and moderation is the key.
Choose the domain name wisely
There is a lot of knowledge in choosing domain names, and the most important thing is to try to choose domain names including keywords. Secondly, see if this domain name has been registered before. If there is a high-quality site with reverse links before, then you will benefit; However, it is also possible that all websites that do backlinks are of poor quality, so you may be unfriendly by search engines for a period of time.
The theme of each article
The more compact the theme of the page, the better the search engine ranks it. Sometimes I find that you have written a long article, covering some different topics, and the relevance is not high, so your ranking in search engines is not good. If you care about the ranking of search engines, you'd better cut such articles into pieces and divide them into several articles with similar themes.
Write articles of appropriate length.
Articles that are too short can't get a higher ranking. Generally, each article has at least 300 words. On the other hand, don't make the article look too long, because it won't help you keep the density of keywords, and the article looks compact. Research shows that articles that are too long will drastically reduce the number of readers, and they will choose to close the articles at first sight.
Avoid content duplication
Search engines have given serious warnings about the same content of multiple web pages in the user guide. Whether these pages are yours or others'. Because a series of junk websites are constantly copying web content (and stealing other people's website content). There is some debate about what kind of content to plagiarize, in fact, it depends on whether these contents are useful for your website choice.
Number of catalogs
When I have too many directories, I will be in trouble myself. I think the level of big websites is higher than that of small websites. Of course, some small websites also have a high level, which is not a standard. The more directories, the more comprehensive the search engine will search. If you have too many pages, you need to organize them so that search engines can crawl them.
Submit to search engine
If you have done all the things that SEO should do in the site, then this site has not appeared in the search engine. That's because search engines haven't started to include, and each search engine allows users to submit unlisted sites. This project usually takes 3-5 days.
SEO is to optimize the overall structure, website layout, keyword distribution and density of the website according to the technology and experience gained from long-term exploration and observation, so as to make the website friendly to search engines, thereby optimizing search engines and improving the ranking effect of the website. Because the ranking rules and algorithms of search engines are constantly changing, and these rules and algorithms are trade secrets, it is impossible to achieve a certain ranking effect. It is understood that there are many people who claim to rank your website in Baidu and Google under the banner of SEO, and this is a means of cheating, so that your website can really rise to a very high position in a short time. But search engines can realize that these means are punished. The website that is punished, the most serious thing is that your website completely disappears in major search engines, or even is no longer accepted. So, I hope you can distinguish carefully, and don't let your website never see the light of day for the sake of temporary interests.
SEO is divided into white hat SEO and black hat SEO. White hat SEO is a formal and reasonable operation, and black hat SEO is a means of cheating. Here are some common cheating methods. I hope you don't use them, or you will regret it.
Portal page ()
Usually, a large number of web pages containing keywords are automatically generated by software, and then automatically transferred from these web pages to the home page. The purpose is to hope that the front page for different keywords can get a good ranking in search engines. When users click on the search results, they will automatically go to the home page. Sometimes you put a link on the home page instead of opening it automatically. In most cases, these portal pages are generated by software. As you can imagine, the generated text is chaotic and illogical. If an article written by a person really contains keywords, it is not a doorway page.
Keyword stack (keyword stack)
A large number of keywords are piled up in web pages, hoping to improve the keyword density and the relevance of web pages to keywords. Keyword stacking can be in many places, such as in the text itself that users can see, and also in keyword tags, keyword tags and description tags. With the improvement of search engine algorithm, keyword density is no longer an important factor.
Hiddentext (hidden text)
Hidden words are words that contain keywords in HTML files of web pages, but these words are invisible to users and can only be seen by search engines. There can be several forms, such as ultra-small font size text, text with the same color as the background, text placed in comment tags, text placed in table input tags, text placed on the invisible layer through style sheets, and so on. Its purpose is also to improve the relevance of web pages. Sometimes, some people will put hot keywords unrelated to the content of the website in these places, hoping that the webpage can get good rankings and traffic under these hot keywords.
Hiddenlink (hidden link)
Hidden links are similar to hidden text, except that keywords are put in the links, so users can't see the links.
Hide page
Some web pages use programs or scripts to detect whether they are visiting search engines or ordinary users. If it is a search engine, the webpage will return the optimized webpage version. If the visitor is an ordinary person, return another version. This kind of deception is usually imperceptible to users. Because once your browser looks at this web page, whether it is on the page or in the HTML source file, you get a different version from what the search engine sees. The way to detect it is to take a look at the snapshot of this webpage.
Subtle words
Many people who do search engine optimization know that hidden words may be punished, so they expose hidden words with fine fonts. Subtle words even use tiny fonts to write sentences with keywords in inconspicuous places on the web page. Generally speaking, these words will be placed at the top or bottom of a web page. Although the colors of these characters are different from those of hidden characters, they often appear in very similar colors.
In the eyes of search engines, declarative words like "All Rights Reserved" are usually displayed in mini fonts. These subtle words are generally ignored by visitors, but the sentences they constitute are suspected of abuse.
Black hat search engine optimization as a distraction
Cover-up method is our common Chinese meaning camouflage, which refers to the way of disguising web pages. First, judge whether visitors are ordinary browsers or search engine spiders, so as to display different web pages. This black hat SEO method is a typical cover-up cheating search engine. The web pages that search engines see are very optimized content, while what browsers see are completely ordinary content.
Black Hat SEO Hijacking Web Page Optimization
Webpage hijacking, also known as PageRacking, is to copy the content of other people's websites or the whole website and put it on your own website. This black hat SEO method is very attractive to webmasters who are extremely short of web content. However, this practice is quite risky and even more despicable. The patented technology of search engine can judge from many factors that the copied webpage or website is not original and will not be included.
Public relations hijacking of black hat SEO
PR hijacking, that is, using deception to get a higher PR value displayed on the toolbar. The method is to use jumps. Generally, when dealing with the turning point of 30 1 and 302, the search engine will regard the target URL as the URL that should actually be included.
Link purchase (link purchase)
Although it's normal to buy advertisements on other websites, sometimes it's regarded as cheating if you buy advertising links purely to improve the level of web pages or manipulate the ranking of search engines. There is a blurred line between how to distinguish normal advertising and cheating. But people who do this are very clear in their hearts. If your website is considered to be cheating on buying links, there is no way to argue with search engines. Because the decision of the search engine is the final decision. What is more serious, of course, is that if your website sells links, you will be in greater trouble.
SEO effect payment
Pay-as-you-go advertising in Rinrin: there is no charge for showing, no charge for clicking, and only charge for answering customers' phone calls, which effectively solves the relationship between SEO and effect. However, this method is difficult to operate in reality.
What does SEO need to master
After understanding what SEO is, it may stimulate your interest in SEO. You will ask what you need to master in order to learn SEO. In fact, SEO is not as magical as you think. To put it simply, you need to adjust the web page so that it has a good "communication" with the search engine, so that the search engine can correctly understand your web page. If the search engine can't find your website, let alone rank it. Because every search engine needs to find your website in a certain way, it requires that your webpage must follow certain rules, otherwise it will be like an old saying in China, "If you don't know you, you won't know you". The guide given by search engines to webmasters is a good guide to website construction.
Of course, this understanding is not enough. You should also master the following knowledge points.
1. Learn how search engines crawl web pages and index them.
You need to know some basic working principles of search engines, the differences between them, how search robots (SErobot or webcrawler) work, how search engines sort search results, and so on.
2. Meta tag optimization
It mainly includes title, website description and keywords. There are also some other hidden characters such as author, category, language, etc.
3. How to select keywords and put them in the web page?
Search must use keywords. Keyword analysis and selection is one of the most important jobs of SEO. First of all, we should determine the main keywords (usually up to five) for the website, and then optimize these keywords, including keyword density, relevance, salience and so on.
4. Understand the major search engines.
Although there are many search engines, only a few play a decisive role in website traffic. For example, English mainly includes Google, Inktomi, Altavista and so on. There are Baidu and Sohu in Chinese. Different search engines have different crawling, indexing and sorting rules. You also need to understand the relationship between search portal and search engine. For example, Yahoo and AOL use Google's search technology, while MSN uses Looksmart and OpenDirectory technology.
5, the main Internet directory
Yahoo itself is not a search engine, but a large website directory, and neither is OpenDirectory. The main difference between Yahoo and search engines lies in the different ways of collecting website content. The directory is edited by hand, mainly including the homepage of the website; Search engines will automatically collect and capture a large number of content pages except the home page.
6, pay-per-click search engine
Search engines also need to survive. With the maturity of Internet commerce, paid search engines have become popular. The most typical ones are Overture and Baidu, and of course, GoogleAdwords. More and more people click on advertisements in search engines to locate commercial websites, and there is also a lot of knowledge about optimization and ranking. You should learn to get the most clicks with the least advertising investment.
7. Search engine login
After the website is finished, don't lie there waiting for the guests to fall from the sky. The easiest way for others to find you is to submit your website to a search engine. If your website is a commercial website, major search engines and directories will charge you (for example, Yahoo charges $299), but the good news is that (at least so far) Google, the largest search engine, is still free, and it dominates more than 60% of the search market.
8. Link exchange and link popularity.
The contents of web pages are linked to each other in the form of hypertext, and so are websites. Besides search engines, people browse the links between different websites every day. The more other websites link to your website, the more visitors you will have. More importantly, the more external links your website has, the more important the search engine will think it is, thus giving you a higher ranking.
9. Reasonable use of labels
The first choice for search engines is H 1. H 1 tag is a learning point of seo.
According to w3cschool.com's analysis, the h 1 tag -h6 tag can define the title. The h 1 tag defines the largest title. The h6 tag defines the smallest title.
Reasonable use of H tags can help us choose the appropriate tag hierarchy to build the document structure.
From the perspective of seo, after SEO optimization, the code of the web page is indispensable with H 1 tag, because its use value is no less than the title. That is to say, the search engine gives the character marked with h 1 a higher weight than other characters (the title is the highest, followed by h 1).
Title tags play the role of finishing touch in the website. The reasonable construction of title tags can not only highlight the theme of web pages, but also help to improve the search engine ranking of websites. The following seo elite engineers will analyze how to use the Title tag reasonably:
1. The title label of each page cannot be the same, nor can the labels of home page, columns page, list page and content page be the same. According to the different content provided by the web page, set the appropriate title label.
Second, the title label setting should be related to the content, and you can set the title, keywords, overview, etc.
Third, the title label should be original and modified as much as possible. The collected and edited content should not be used immediately. It should be modified appropriately to add some original factors, which will help to improve the inclusion of online search engines.
Fourth, don't set too many title tags, try to be within 25 words, the simpler the better, and summarize the theme of the web page.
5. Don't set the keyword density in the title tag too much, one is better, not more than three. Avoid piling up and repeating keywords. If the keyword density is too high, it will easily lead to the disgust of search engines, which will lead to the cheating of search engines and the demotion of websites.
[Edit this paragraph] The latest SEO optimization formula.
SEO=∫Clock=∫C 1+L2+K3+O4
1, ∫ is an integer symbol, C = content, L = link, K = keyword, O = other. SEO is a long-term process of integrating "time", and the content is the core;
2. c1-rich content is the first element, and the importance of arranging content in the order of original, pseudo original and reprint satisfies the user experience;
L2-The rationality and richness of links are the second factor. Reasonable and effective internal links are as important as rich external links, especially pages with high relevance and high Pr value in external links.
4.K3— Keyword factor is the third important factor, including: reasonable title, description, keywords, density and reasonable layout of page keywords and related keywords;
5. O4-other factors, such as domain name, site age, server, website architecture, typesetting, neighbors, Url, map, etc.
This formula is well written, which expounds SEO optimization in a very general way and takes into account the problems that need attention in SEO optimization.
According to this formula, many valuable concepts can be found, and interested friends can taste it carefully, but only if you can understand this formula.
Mathematically, this formula is called indefinite integral formula. If this formula is written as a definite integral formula, hehe, the effect will be great, but in this case, SEO optimization will be transparent.
At present, SEOer seems to be very concerned about the spider experience. In fact, the user experience is also very important. I use the following formula to summarize:
SEO= user experience+spider experience. You can even use SEM, SEO/SEM theorem: SEO/SEM = UE+SE;
Noun explanation:
Search engine marketing (SEM) is a new form of online marketing. What SEM does is to comprehensively and effectively use search engines for online marketing and promotion. SEM pursues the highest cost performance, gets the most visits from search engines with the least investment, and generates commercial value. The SEM here does not include payment methods such as bidding ranking and purchasing keyword advertisements.
UserExperience (UE) is a purely subjective psychological feeling established by users in the process of using a product (service). In the early software design process, the user experience mainly came from the interaction between the user and the man-machine interface, but now the popular design process focuses on the user-centered. What is the goal of user experience design? The most important thing is to make the product useful, which refers to the needs of users, followed by ease of use. Specific to website optimization SEO, a website user experience is good, that is to say, users can easily find the information they need on the website, without any obstacles that affect users' browsing information, such as pop-ups and advertisements.
SEOExperience (SE for short): It is the evaluation of websites by search engine algorithms, which rank websites well. How does the algorithm evaluate the website? A large number of high-quality external links, original articles, high-frequency updates, good website structure algorithm, user experience and other evaluations that meet the algorithm are all good.
Prove:
How does user experience improve SEO ranking? First, a good user experience can improve the conversion rate of PV value products on the website. The most important thing is to turn traffic into users, and the more traffic users accumulate over time.
Suppose there are two websites, A and B, with the same parameters except the different traffic.
The flow of a >; B's traffic, then a's weight and ranking are better than B.
Namely: websites with good user experience have good weight and ranking.
[Edit this paragraph] Website SEO problems

3. the website was hacked by K.
4. Failure to achieve the desired results
5. The ranking is unstable
6. One-sided optimization of website, short board effect of SEO
7. The server is unstable
[Edit this paragraph ]SEO security
This is also a problem that many webmasters easily ignore in the SEO process of the website. It is suggested to start the security strategy from the following aspects.
1) Choose a stable server or virtual host to ensure users' stable and smooth access to the site.
2) Make a comprehensive analysis of the program of the website, remove the complicated code, and use a simple DIV+CSS layout to eliminate hidden dangers.
3) Update the server system regularly, maintain a safe and stable operation system, and ensure the safe operation of the website.
4) The account and password of the backstage administrator of the website should be as complicated as possible.
5) Try not to use the default database path.
6) Update vulnerability patches frequently. For example, friends who use CMS as a website often contact developers to update patches.
7) Pay attention to the latest vulnerability program officially released by Microsoft and update it in time.
Safe website space and operating platform can better serve search users and bring stable customer sources, and security issues cannot be ignored. Giving users a safe and stable website platform will definitely bring you the greatest benefits.
