Search engine Optimization (SEO) is the search engine has a good collection of pages of the process, the appropriate SEO is conducive to spiders crawling your site, so that your content with the search engine algorithm to confirm it with the keyword highly relevant.

The purpose of optimization is to make the content of Web pages easy for spiders to understand, the following I will be included in a new Baidu content to explain, I search with a complete title, its purpose is to reflect more keywords in Baidu Natural search results page, can better explain how the search engine is how to crawl your Web page.

(Figure 1:100 of the most common natural search results list)

Seoer is usually concerned about the main part of the Web page of the natural search results, Baidu and Google search results page is roughly the same, the search results page is usually the top, right, tail are advertising links, hot keywords will have ads, and I use so long words are unpopular words, no ads.

Page title is important

As shown in the figure, search engines usually crawl the title of the page is the title part of the HTML code, so that the page title is written on the search engine rankings have an important significance, usually the page title of the optimal format: article title-column title-site title.

It doesn't necessarily show description.

The second line of the description will usually intercept the description part, but more often grab the first 200 words of the body, if you want to say the specific display description or intercept the text, is related to the user search keywords. For example, in figure one, Baidu intercepted the keywords in <h1>, because Lou Blog in the "internet" this keyword. The following figure can intuitively reflect these problems.

(Figure II: Search engine crawl keyword distribution list)

The combination of figure one and figure two, we can clearly distinguish, Baidu in the end to show what part of the page, title, <h1>, intercept the text and content of the keywords.

Users search for keywords in the search results are highlighted in red, users can very quickly see whether the page is what they want, usually Baidu and Google's search results similar, I do not say more here.

Density and distribution of key words

Through the above two graphs, it can be seen that I search for two major keywords "internet" and "Hong Kong people", through figure II we can see that these two keywords in my list of the 6 most of the show, they are evenly distributed in various parts of the content, especially the title and the title section. Of course, because of my search keyword problem, the entire title has been searched, so the distribution is more uniform.

And the density of keywords, at least I never care about, if you write the article at the same time also consider the keyword density words are very tired.

I think, through the above simple analysis, you should be able to get a general understanding of the search engine to crawl your page what part of it?
