In fact, a long time ago, in just entering the SEO business, have heard a lot of predecessors said, the title of the description in the keyword ranking accounted for the proportion, but with the search engine ranking mechanism changes, many friends in the industry also put forward the proportion of title questioned, the proportion of lower or even "ignore" The story of a wave more than a wave. Today I just want to tell those comrades, in fact, the search engine on the title description of the weight has never decreased, and will never be reduced.
We can analyze, spider through the link crawling to a website, then it can first see what is it? Undoubtedly is the title, and the second is keywords, description and so on, then is H1,H2, the body and so on all, then spider rely on what to grasp the core of this page? is actually title.
Spider in the first crawl the title of the page, there will be a record, the title of the first two words will be spider thought is the station's core words, and then continue to crawl down, the next time in the text to meet the word, Spider will make a record, Until you crawl through the entire page, Spider calculates the number of bytes that appear on the page and the byte of the entire page (the so-called keyword density), which determines whether the word is the core word for the page.
Analysis of the above, we can make a hypothesis, if the search engine can put the title of the weight of this block, then spider rely on what to grasp the core words of a page, to know that spider is not human, you must take the initiative to tell him, otherwise it will know what you want to give him?
