In the previous article, we talked about the considerations for Seo and website development. Article Continue with the previous article to explain how to select keywords reasonably and effectively.
We all know. search engines search for webpages with matched content based on keywords you enter in the text box. if it is found, it is displayed in the search list. Is it true that you only need to specify the corresponding keyword viewer to see Your webpage. no !! If your page is placed after dozens of pages, who can turn to more than a dozen pages and then search for webpages that meet the requirements? According to our general search habits, most of them can be viewed. First two pages , Maybe most of the page views are only the first page, so we have to find ways to route our page to the first page. or the first few places on the first page (this is very difficult for a new site to make general keywords ). let's explain this through examples.
First, understand the HTML page Structure
<HTML>

XX



XX

</Html>
The search engine uses the HTML page structure to deploy keywords at the same time (a bit like traversing a binary tree. I don't know if this is true. I have not learned the data structure well .), follow this understanding. the search sequence is HTML-head-title-meta-body-Div .. from this point of view, title is the most important part of specifying a keyword (this will be explained in the next chapter). How to Select a keyword? We also need to use a tool for analysis. The installation process will be minimal at http://ff.seoquake.com/. when the installation process is successful, the search criteria will be shown below:

Each page has a corresponding prvalue. external link. and include page prompts. through this page, we can analyze the strength and ranking of each keyword, as well as the ranking of Key competitors. what aspects should I start with when analyzing keywords?
1. The number of pages indexed by keywords. In comparison, the more pages indexed, the more difficult the keywords are.
2. Search for the PR value of the home page of the list. There are only 10 places on a page. If the PR value of these 10 websites is generally higher, the harder the keyword is to do.
3. Search for the number of external links on the homepage. The more external links, the more difficult it is to exceed.
4. The number of pages on the site indexed by Google. The more pages indexed, the more difficult it is to exceed. |
This is a few basic analysis points. but we can see that. some pages with low prvalues are also listed in front of websites with high prvalues. this is because Google ranking is based not only on the four points listed above, but also on the keyword placement location on the top page. and the page keyword density. this can be analyzed through the pageinfo of seoquake (see figure ):

Therefore, if you want to rank first, there are many factors to consider. Google's rankingAlgorithmIt has never been made public. this requires constant accumulation of experience. we cannot trust the absolute influence of the PR value on the website ranking. however, it cannot be ignored. Therefore, it is much better to select a good keyword than to create 1000 external links.
In the next section, we will focus on the application of key words in title, keywords, and description ..
