Many colleagues who engage in search engine optimization often ask questions about keywords. For example: how many keywords or keyword phrases a page has is more beneficial to ranking; or, how much keyword density a page has is more beneficial to ranking. Let’s talk about the relationship between keywords and rankings based on my personal experience.
Within the industry, people prefer to use the keyword density in a page as a reference factor for search engine rankings rather than the number of times a keyword or keyword phrase appears on a page.
So what is keyword density? Many people think that keyword density is the percentage of keywords in the visible content (space) of a web page; in fact, it is not. The so-called keyword density should refer to the keywords and the number of words in a page. The percentage of the content of the html code. It seems to be a relatively abstract concept. Let me explain keyword density to you with the following code:
<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>
Judging from the above code, except for the HTML code, the remaining content 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. Let’s calculate the keyword density of keyword1. Since keyword1 appears 4 times in all the content, we think that the keyword density of keyword1 is 4/16=25%; from this example we When calculating keyword density, HTML code tags are excluded from the total content of the page.
After understanding what keyword density is, let’s continue to explore the relationship between keyword density and website ranking. According to observation and research by some professionals, in most search engines, the keyword density between 2% and 8% is a more appropriate range, which is beneficial to the website's ranking in search engines.
Keyword density is an important factor in ranking, and of course it cannot be ignored, but the most important thing is content. In order to achieve a keyword density of 2% to 8% without sacrificing content quality, many people deliberately add optimized target keys to the page. In fact, sometimes doing so will have the opposite effect.
When building a website, it is best to create your own content, because the content written combined with your optimization knowledge is the "best" content. This depends on your overall level. To evaluate whether the content of an article is appropriate or not, consider two aspects: one is the fluency of the article, and the other is the density of keywords. The position and frequency of keywords in a good article not only do not affect the fluency of the article, but also meet the "best" optimization requirements.
Generally, what we optimize is not a word but a phrase. For example, "search engine optimization" includes the two words "search engine" and "optimization". When optimizing, we must not only emphasize "search engine optimization" but also "search engine". with "optimize". Many people mistakenly think that his focus is only on "search engine optimization", so he keeps repeating this phrase in the article. (Note: Be sure to remember that the "search engine optimization" you are optimizing for is a phrase and not a word. If you optimize for "search engine", then you do not need to separate "search" from "engine"), search engine When identifying keyword phrases, the entire phrase will be interpreted and divided into multiple words for interpretation.
I think the description at the top of this site should be a good example, optimizing for the two most important keyword phrases "search engine optimization" and "website optimization".
