The main ways to increase keyword density are:
Add keywords sensibly to titles, descriptions, and keyword tags: Since these locations are relatively sensitive to search engines, they should be determined as soon as possible. The basic principle is that the title should accurately summarize the content, neat and fluent;Keywords can be repeated in the description;You can add the words you want to rank for in the keyword tag.
Keywords appear naturally in the content of the web page: Search engines like web pages with rich content and natural and reasonable keywords. Keywords can appear in the title, first paragraph, last paragraph, etc. of the article.
h tag:h tags can tell search engines which content is most important, so you can include keywords in h1 or h2 tags.
** Add keywords to the file name and alt attribute:** file names and text in the alt attribute can be read by search engines, so keywords can be added to it.
Add keywords to the anchor text of the exported link: The anchor text of the outgoing link can provide search engines with more information about the page, so you can include keywords in it.
**Arrange keywords reasonably in the three tabs of the homepageThe three main tags of the :** homepage include the title tag, the description tag, and the keyword tag, and the content of these tags is used by search engines to evaluate the relevance of the web page, so the keywords can be arranged reasonably.
Keywords can be placed in the URLKeywords in the :URL are also read by search engines, so keywords can be placed in the URL reasonably.
Make keywords bold: Bold keywords can be made more likely to allow search engines to better identify the key content in the page, so keywords can be bolded in the page.
Each column page is placed with the corresponding keyword: Each section page has its own specific topic, so you can place the corresponding keywords in each section page.
Take advantage of the on-site search function: Do an on-site search on the homepage, and add default search keywords to the on-site search.
Take advantage of quick links: Make quick links at the bottom of **, and add keywords to the quick links.
The above methods can help increase keyword density, but you need to be careful not to over-stuff keywords so as not to be perceived as cheating by search engines. At the same time, user experience is also very important, don't sacrifice user experience for the sake of search engine rankings.
