Search engine Optimization (search engine optimization) (SEO,) is a way to adjust the website by understanding the operating rules of the search engine in order to improve the ranking of the target site in the relevant search engine.
The core module of search engine generally includes crawling, index, retrieval and sorting, and its working principle is generally composed of three steps: crawling / crawling, preprocessing, ranking and so on.
We search the keywords in the search engine, search the data through the ranking program, calculate the correlation of the data, calculate the weight for each result, and finally rank the weight and return the search results.
From this we can know that all we can do is optimize in the search engine spider crawling page phase. Not the search phase.
The search engine grabs the page through the link in the page or by specifying the starting crawling link. All we can control is the site itself. In order for the site to get a higher ranking, it is necessary to make the search engine spider crawl to the target page faster and grab the key data more accurately.
Deceiving search engine spiders through hot words will greatly reduce the ranking of websites
