There are often many search engine optimization colleagues asking questions about keywords. For example, the number of keywords or keyword phrases on a page is more favorable for ranking, or the number of keywords on a page is more conducive to ranking. Next I will talk about the relationship between keywords and rankings in my personal experience.
In the industry, people prefer to use the keyword density in a page as a reference factor for search engine ranking, rather than the number of times a page contains keywords or keyword phrases.
So what is the keyword density? Many people think that the keyword density is the percentage of keywords in the content visible on the webpage (<body> </body>). Actually, it is not, the keyword density should be the percentage of content between a keyword and html code removed from a page. It seems like a relatively abstract concept. Use the following code to describe the keyword density:
<Html>
<Head>
<Title> keyword1, keyword2, keyword3 </title>
<Meta name = "keyword" contend = "keyword1, keyword2, keyword3">
<Meta name = "description" contend = "keyword1 is keyword2">
</Head>
<Body>
Keyword1 is keyword2, keyword3 is a beautiful glass!
</Body>
</HtmL>
From the above code, apart from the HTML code, the rest is (from top to bottom ):
"Keyword1, keyword2, keyword3"
"Keyword1, keyword2, keyword3"
"Keyword1 is keyword2"
"Keyword1 is keyword2, keyword3 is a beautiful glass! "
There are 16 words in total. Next we will calculate the keyword density of keyword1. Because keyword1 appears four times in all content, in this example, the keyword density of keyword1 is 4/16 = 25%. When calculating the keyword density, the html code tag is excluded from the total content column of the page.
After learning about the keyword density, we will continue to explore the relationship between the keyword density and the website ranking. According to some professional observation and research, the keyword density in most search engines is between 2% and ~ 8% is a more appropriate range, which is conducive to ranking websites in search engines.
Keyword density is an important factor in ranking. Of course, it cannot be ignored, but the most important thing is content. Many people try to reach 2% ~ 8% of the keyword density does not mean the quality of the content. Deliberately add the key to the optimization goal on the page. In fact, sometimes this will lead to the opposite effect.
When creating a website, it is best to create your own content, because the content written based on your Optimization Knowledge is the "best" content. This is determined by your overall level. The evaluation of the content of an article is based on two aspects: first, the smoothness of the article, and second, the density of keyword appearance. The keyword position and frequency of a good article not only does not affect the smoothness of the article, but also meets the "most" optimization requirement.
