For page-based SEO optimization, the keywords need to appear in the appropriate location of the entire page.
So which locations are suitable?
First, in the title and title sections.
In the meta keywords section.
In the meta description section.
The closer the text part of the body is to the beginning of the page, the better.
In the first sentence of the entire body text.
In the URL.
In the H1 or H2 label.
In the link text of the station link.
Link text of the external link.
In the URL of the link.
You can also set the Alt attribute of the image tag.
In the HTML file comment.
Keywords can be placed in the above positions. The larger the weight of the first few keywords for search engines.
There is a degree problem here, that is, if you place the keyword above is good for keyword ranking, but if you put the keyword in all the above places, then, it is very likely that you will be punished by the search engine and think that you are over-optimizing.
It should be noted here that keywords should be placed naturally and not hard. It can be seen one or two times.
There are also a few notes that search engines do not like:
1) if the keyword in meta keywords does not appear in the body of the webpage content, it will be considered as a stacked keyword.
2) for an English webpage, do not use uppercase letters in the title and meta tags.
3) do not use text with a small font size. The search engine knows what you are doing.
