I believe many of my friends have encountered this situation, with the most new websites. Many webmasters use www domain names when issuing external links. A friend of mine has 35,000 baidu related domains with www. In this case, no matter how many external links with www are posted, you may not be included. Below I will analyze the reasons and solutions for this phenomenon.
The preferred domain was selected incorrectly, and no processing was done after parsing
When the domain name of the website was resolved, both those with www and those without were resolved, but after the resolution, no treatment was done to the two domain names. Baidu judges that the domain name without www is the preferred domain name for your website, so no matter how many external links you send with www, it will not work. At the same time, the internal link part of your website uses a large number of relative path methods, which is even more unfavorable to the inclusion of domain names without www, because in the eyes of search engines, these are two websites.
The problem has been found. Let's talk about solutions to this problem.
1. Make a 301 redirect to two domain names.
Make a 301 redirect to all domain names without www and point to domain names with www, which will generally take effect after half a month. Don't easily remove the resolution of domain names that do not include www, because doing so will lose all the weight of the pages originally included by Baidu on your website, and the one you have with www will be considered a new site for review.
2. All links in the station adopt absolute paths.
If you use a relative path, then search engines will naturally think that these pages of yours are still without the www domain name, and the weight will of course be attributed to those without the www domain name. Therefore, the internal links of a website must adopt an absolute path method to use the domain name with www, so that the weight will be passed on to the website with the www domain name.
3. Increase the update of original articles after the redirection.
At this time, you must increase the update of the original content of the website, because even if you do it, the 301 search engine will still have an inspection period for your other domain name with www, which is slightly different from the new website. Weight is generally not lost. In addition, it seems that Baidu's judgment on 301 redirects is not so good. If your website is a new site and contains very few other domain names, which is basically not helpful to ranking, you can also directly remove the resolution of domain names without www. Of course, this is the last resort, and I recommend you do 301 redirects first.
If this happens to your website, don't worry, you can find out the reason after slowly analyzing it. This is also the reason why many webmasters friends emphasize that it is best to use absolute paths for intra-site links when telling their experience in building websites. Adopting absolute paths is not only more search engine friendly, but also prevents situations like this from happening.
