Bidding: the result is quick, and there are no difficult keywords, but the price is high, the management is troublesome, and there are malicious clicks due to the independence of search engines.
Website optimization: it takes 2-3 years to see the effect, but the price is low, there is no independence of search engine, and the management is simple.
The overall effect of optimization is far stronger than bidding, and the price is several times lower. Those companies that claim that "it is so expensive, it is better to bid" just compare the price of website optimization with the bidding of Baidu's daily cost control. They didn't take into account that the optimized website can improve the ranking of all search engines, and also ignored the illusion caused by the bidding cost of other search engines.
Generally speaking, optimization and bidding have their own advantages. Shanghai Kaicheng SEO experts recommend customers with sufficient advertising budget, and consider ranking through bidding for a period of time to optimize the website at the same time during this period. When the optimization is over and the ranking meets the requirements, the bidding will be withdrawn, which can be excessive and will not affect the marketing. Marketing is the first for any enterprise, and optimization and bidding serve marketing and are the core of advertising.
