Want to become a master SEO, for the search engine principles have a very deep understanding is necessary, but for many people, the basic principle will be able to. But if the basic principle is too lazy to see, it can only be a monk bird (vegetarian-> cuisine).

First, give the search engine a search request. Each word in the request is called a search term. Most of the time people search one or several words (such as "SEO" and "seo Tutorial"), there are a few times will search a short sentence, more appear in the search news.

Second, after the search engine received the command, the search request separately (Chinese and other minority language unique Chinese participle, very complex problem), divided into a pile of words, and then to each word corresponding to the index library inside to find the corresponding information. Finally, the information that the pile of words shared in the index is presented.

Again, of course, ranking to have a sequence, after a series of algorithms toss, the end result came out.

Say simple, which involves a lot of SEO tangled problems, such as the determination of the final weight related to the weight of the Web page, and the relevance of the search term, as well as statistical user behavior, and so on, each can be divided into many kinds. There are at least 200 factors that affect rankings in search engines (or more, as Google said many years ago). Even if all know that more than 200 kinds of factors, more than 200 split combination, optimization of the possibility of infinity, so even if the search engine's own site to do SEO, have to go to another SEO experts, very embarrassing things.

Not long-winded, slightly above three points to expand again. After you enter a bunch of search items, the search engine analyzes the nature of the search term. For example, stop Word is very small, search term inside one or less one like "" of meaningless words, the impact on search results is relatively small. It can be expected that the role of adjectives and verbs will probably be weakened, because most of the search requests, the subject is the noun above.

Other words, such as "Shanghai SEO", which "Shanghai" in the entire Web page collection, the number of times than "SEO" more, so this is a more common word, its impact on the rankings will be smaller. Otherwise imagine, for example, Sina Shanghai one day to get out of the news about SEO, the page appeared a number of "SEO", then it will be because of its web page weight than other do "Shanghai SEO" The page is much higher, it will line up to the front, the world from chaos.

But in fact it is not, because in this case ranked "SEO" the importance of far more than "Shanghai", it is difficult to appear like the above mentioned such a mistake. So, some people like to use "regional SEO" in the article as the first person to write the article, this I am very disagree, look uncomfortable do not say, the role of ranking is often not as impressive as expected.

But if it is a small area of SEO is another matter, because some place names on the internet than the frequency of "SEO" lower, it may need to pay more attention to place names. But not necessarily, because often place names are in the search engine's gazetteer, most of them will have special treatment. But if this area is small to place names have not entered the search engine dictionary, it is indeed the site more than a few times "regional seo" better, but this time is not necessary, the word could have been easy to do up the rankings.

In short, it is anyway, do not in post the first person into the "regional SEO", no big use of SEO, the impact on the user experience is very large. Basically I pass this kind of blog is ruthless Skip.

Then one point: the exact match is always better than the inexact match. For example, "paper published", "published papers", the two words of the search results of the previous pages of the site is not the same. Although the word, these sites are two words in the index of each of the existing, but because the record index, but also recorded the location of words, you can find out the order of words. In addition to word matching, the order of occurrence is precisely matched, which is always the best. But for example, search "SEO Shanghai", although the results and "Shanghai SEO" There are differences, but far from the previous example of a big difference, because no one specializes in "SEO Shanghai," the word. So there is no exact match, the impact may not be large, see the specific words of how the situation.

Finally, each word corresponds to an index, which records the file number, the file number corresponds to the URL of the search term, and the title of the URL, and the search engine extracts the site summary. These are the main components, as well as the location of the words in the Web page and so on. When the search engine received the request, not to search a bunch of web sites, which is slow to unrealistic, it is to search for a well established index library. Just pick up some of the data mentioned above, so you can guarantee the efficiency of the search results returned. If as a SEO personnel, the principle of the search engine do not understand, there is talk about how to optimize the site?
