(Updated on August 31, 2016: 10 years have passed, Mr. Wu Jun is now one of my most admired people. There are more scientists, but I can write IT to be victorious, full of emotions, and still on TV show. I didn’t see a few when I talked about it.)
Not that he did not write well, but did not reveal any secrets. If a search engine engineer simply makes a search engine algorithm in the way he writes, it would be the worst search engine. In this article, we only talked about one of the earliest factors in determining the relevance of web pages and queries, namely keyword density.
The reality is that keyword density has fallen to a small fraction, and more important factors should have been used to judge relevance to web queries. Today, talk about page optimization for query keywords.
It should be noted that the relevance of the file is not only determined by the page itself, but also includes link analysis, domain trustworthiness and other factors. Today only talk about keyword optimization in the page.
My feeling is that 3% to 7% is appropriate, but the weight of keyword density is already very small. Many of the top-ranked webpages may have a keyword density as high as 30%, or there may be no keywords at all. So as long as you logically write your web pages in grammar, you don’t have to worry too much about keyword density.
Keywords should appear in the title tag of the web page. The title tag Title Tag is a very important factor at present and should contain your most important keywords.
In addition, the description tag , the keyword tag , the keyword tag , and the image ALT tag can all be placed in the keyword, but be careful not to pile up keywords.
Keywords in the body of the web page
As long as you write articles normally, keywords will inevitably appear in the body of the article. It’s best to put keywords in the heading of the body heading. H1-H3 has a higher weight than normal text. This is also very logical, because the title is naturally what this article should discuss.
In addition, you can use black and italic to emphasize keywords, but one or two times is enough.
You can put keywords in the first sentence of the text, that is, the first sentence of the first paragraph, which is also a more important factor.
You can also put keywords at the bottom of the page, of course, logical and grammatical, and user-friendly.
Keywords in the URL
For English web pages, keywords appear in the URL, which is a bit helpful. The help for search engine correlation algorithms may be small, but it is quite helpful for users. Because the search results are listed in the search engine, the user can determine from the file name what the page is discussing.
Keywords can be in the domain name, in the directory name, or in the file name, but the keywords should not be stacked in the URL.
Keywords appear in the link
Keywords should appear in the link text of the web page export link , which is a very important aspect. In fact, to some extent, the keywords contained in the export link are more important than the keywords in the external links to this page .
Not only when you link to each other within your website, you need to use keywords as link texts. You should also frequently quote and point to other related documents in the article, and use keywords as link texts.
Are there keywords in these places? It is likely that they have been over-optimized
