Once the keywords most relevant to user search behaviors are determined, you need to insert the keywords into the content and HTML. The most important areas include:
Although keyword optimization can increase search traffic, do not sacrifice the quality of content in this process. The content should be written for the user first, and the second is for the search engine!
When the keyword appears too frequently on the page, it is obviously trying to fill the page with dishonest content, deceiving the search engine to attract traffic. The search engine uses a simple mathematical formula and some basic logic languages to determine whether a word is artificially highlighted on a page. This formula helps determine the keyword density of a page.
The search engine also looks for other words around the main keywords to determine whether they are naturally contained in the content or partially filled with words on the page for deception.
1. Document name (logo image file name, external CSS file name)
2. Link tag
3. alt attributes
4. Table elements such as <th>, <caption>, and summary attributes
5. title attributes
6. <acronym> and <abbr> labels
7. <title>
8. Title tags, especially
9. The first line of the page
10. meta description
11. <strong> and <em> labels
12. URL
In addition to placing keywords in HTML files, you must add them to the content. It is easy to get caught in a series of keyword optimizations, and before you know it, the content will read very strange.
