I often site a website in Baidu and find that "In order to provide the most relevant results, we have omitted some entries with similar content. Click here to see all search results.". The optimization of similar pages is also a detail that needs attention in SEO work. The cleaning and optimization of similar pages may mainly involve web designers. The generation of similar pages is mainly because such pages have less main content and more conventional auxiliary content. This results in similar pages, which are of low value to search engines.
When GOOGLE had "Supplementary Materials" before, similar pages were easily labeled as "Supplementary Materials" by Google. There are other factors that contribute to the creation of the Supplementary Materials page, such as descriptions. However, similar pages are also a factor.
Similar pages may be at the end of the page value in the overall web page structure of the website. Even for web pages that are not very important, it is difficult to obtain search engine rankings.
Formation of similar pages
In each web page, the text content must occupy a relatively important or large proportion of the entire content of the web page. Generally speaking, when the main text accounts for only 20%-30% of the entire web page, it is easy to form a similar page.
The importance of main content in web pages
The text of each web page is the core content of the web page. Website administrators should not just write a few words and update it as the original content of the website for the sake of updating the website or for convenience. The text content of each web page should not be less than 500 words. If the number of words is too small, search engines will analyze the theme of the web page. If the theme of the web page cannot be analyzed, it will be detrimental to the search engine ranking of the web page.
The impact of similar pages on the website
If there are too many similar pages, it will dilute the quality of the website, including weight, PR, links, etc. This affects the overall performance of the website on search engines, such as unsatisfactory ranking performance for long-tail keywords. The more serious punishment is to deem the website administrator to have SEOSPAM behavior, and ban such web pages from inclusion or demote the rights.
How to optimize similar pages:
1. Prevent the text content from being too small. This is one of the best techniques to prevent similar pages from being generated;
2. Let search engine spiders grab the text first;
3. Reduce unnecessary content structure in web pages.
Website optimization is actually how to make website content better and remove or improve bad things. The optimization of similar pages should also be a relatively important basic optimization work. In website optimization, you should consider how to avoid too many similar pages. At the same time, it is recommended that everyone pay attention to the content length of the added pages during daily website updates, and whether the main text can adequately describe the page theme.
