Google is welcomed by webmasters and Internet media service companies because it not only uses keywords or proxy search technology, but is based on advanced network-level technology. Other search engines provide searchers with rough search results obtained from various channels, while Google provides its searchers with highly accurate search results generated by itself. This is why webmasters will do everything possible to improve their website's ranking in Google.
Another reason for Google's popularity is its website indexing speed. It usually takes only two weeks from your website being submitted to Google to being included by Google. If your website has been included by Google, then usually Google will traverse and update (re-index) your website information once a month. But for those websites with high PR (Pagerank), the Google index cycle will be shorter accordingly.
Google's indexing/re-indexing cycle is shorter than most search engines. This allows the webmaster to edit and modify the page properties of the website, such as page title, the first few lines of text content, title, keyword distribution, and of course the number of external links. Then they can quickly find out whether these changes to the web page are successful.
Because Google is so popular, you need to know how Google's search engine works. If you don't know how it determines your ranking, websites that are only slightly familiar with Google's ranking algorithm will rank higher than you. Now let's take a look at Google's ranking algorithm.
Google's ranking algorithm mainly uses two parts. The first part is the text content matching system. Google uses this system to find web pages related to search words typed by searchers; The second part is also the most important part of the ranking algorithm, which is the Pagerank technology patented by Google.
Let me first introduce how to make the website relevant, that is, the algorithm of text content matching:
When searching for website keywords, Google will give higher weight to the keywords in its meta-title. So you should make sure that the title tag of your website contains the most important keywords, that is, you should decide the content of the page title around your most important keywords. However, the title of a web page should not be too long, and it is generally better to be between 35 and 40 characters.
As we all know, Google does not use meta tags such as keywords or description tags. This is because the actual visitors can't see the words used in these meta tags. Moreover, Google believes that these meta tags will be used by some webmasters to fraudulently place some hot keywords unrelated to their websites, so as to improve their websites' ranking of irrelevant keywords and gain more visitors through improper means.
This feature that does not support Meta tags means that Google will generate a description of a website from the first few lines of a web page. In other words, you'd better put your keywords or key phrases at the top of the page, so that if Google finds them, it will improve the relevance of your website accordingly. Once Google can't find such relevant content, you have to make great efforts to make the rest of your page relevant.
When determining the relevance of the website, Google will also consider the keyword density of the text content in the webpage, so you should ensure that keywords and key phrases appear several times throughout your webpage. But remember that "too much is too late", the keyword density of 6- 10% is the best.
Other strategies to increase page relevance include: placing keywords in the title content and making the keywords in the content as bold as possible. Google now will also index the ALT attribute text of the picture and make statistics in the correlation calculation. Therefore, you should include keywords in your ALT attribute to increase the relevance score of the website.
The last trick to increase the relevance of the page is to let the external text links on your website contain your keywords. Including keywords in external text links can effectively improve the relevance score of your website (Google also mentioned in its description of PageRank technology that when calculating the page level, it will analyze the external links of the website and include them in the relevance).
How many keywords should a text link contain? This is a matter of opinion. But I noticed that many websites in their link exchange area provided corresponding text links. For example, "Welcome to make friendly links, please use the following code to establish a link to this website."
Above, we introduced some knowledge about how Google calculates website relevance and how to increase website relevance. But how does Google measure the quality of a website? The answer is-Google Pagerank is the system.
