First of all, we should understand five factors that affect keyword optimization:
1, PR value of web page
The value of PR ranges from 1 to 10, and 10 is the perfect score. The higher the PR value, the more popular the page is. Web pages with high PR value are preferred in search engine search results. Therefore, the webmaster can optimize the effect of keywords by improving the PR value.
2. Keyword density
Keyword density and keyword frequency are essentially the same concept, which are used to measure the ratio of the total number of keywords appearing in web pages to other words, usually expressed as a percentage. Relative to the total number of words on a page, the higher the frequency of keywords, the greater the keyword density. Keyword density is controlled in the range of 2% to 5%, which is beneficial to keyword optimization.
3. Meta tags
META tags are used to describe the attributes of HTML web documents, such as author, date and time, web page description, keywords, page refresh, etc. The rational use of tag attributes can improve the user experience of the website.
4. Similar keywords
5. Relevance of linked topics
Secondly, we should follow the basic principles of keyword selection.
1, keywords should be closely related to the content theme of the website. 2. Keywords should be precise but not broad. 3. The keywords should not be too special. 4. Think from the user's perspective. 5. Choose the keywords with the least competition.
Finally, some tools can be used to help optimize keywords. For example, webmaster tools, love stand net, chasing subnets.
