Hello, everyone! We already know the use of Baidu Index to get the site's "theme" (Core keywords).
Now we need to extend the keyword.
Understand two concepts first:
Keyword density------The keyword density of a Web page refers to the text of a Web page (excluding HTML tags), the number of times the keyword appears and the total text word amount.
Explanation: If a page has 100 words or words, the keyword appears 2 times, then the keyword density of this paragraph is 2%
The calculation formula of the keyword extensibility-----This quantity is more complicated. You can understand that:
1, if there is an article is reported "school", then the article will certainly appear "teacher", "classmate", "classroom" and so on words. If it does not appear, the article is certainly not related to the "school", the more frequent the number of these words, the "article" and "school" the more relevant, so when users search "school", the article is more likely to be ranked in front of the Serps (search results page).
2, to my website for example, the core of this site is "dress collocation" and "clothing collocation." This site to talk about this collocation problem, sure to use the "Men's Match", "Women's collocation", "collocation skills", "brand apparel" and so on keywords, that is, if the site does not exist these relevant keywords, search engines will not recognize this site and "dress collocation" related.
3, we can compare the extension of the keyword to "find relatives." The intimacy level of each relative is different. In point 2, "menswear collocation", Women's Wear collocation, "collocation skills" and "brand apparel" are "costumes collocation" and "clothing collocation" relatives, but out of Chinese language habits, "dress collocation" focus on "collocation", so the top three keywords are the closest relatives of the core keywords, "brand apparel" can only be counted " A distant relative of dress collocation. Of course, close relatives and distant relatives are relative.
So how do we expand the site's keywords?
Very simple, since we are the optimization of Baidu, then please Baidu to help.
Use Baidu to promote (now must go to Baidu to promote registration to see "more relevant") Search, ok! these blue bar longer keyword is your site keyword.
Now let's write down the first 7 keywords.
Please note: These 7 keywords are for reference, not absolutely to use, in order to illustrate the needs of the problem, you can think of several "most relevant keywords" to replace a few of the 7, you can also modify the keywords and combinations.
