As a webmaster, exchanging friendly links has become a required homework for us, and it is also a very important part of website promotion.
However, there are always some people who only want others to link to them and do not want their own website links to have links to other websites, so they rack their brains and use various means to try to exchange friendly links with others that harm others and benefit themselves. If kind-hearted webmasters If you don’t check for a while, you can easily fall into the trap without even knowing it. So how to avoid the trouble of friendly links?
1. Websites blocked by Baidu still have PR: When many webmasters exchange friendly links, they only consider Google’s PR as one factor. As long as the PR meets the requirements, they will happily exchange links. However, some websites, due to excessive SEO, etc. The reason is that it was blocked by Baidu and the site cannot be searched on Baidu. However, it still exists in Google's index and has PR. Many such websites are frantically applying for links in the hope of being re-included by Baidu. However, an article "Revealing Search Engine Index Problems" mentioned that exchanging links with such websites does more harm than good, and it is easy to suffer association penalties. . At the same time, webmasters need to pay attention to the fact that some sites, although not blocked, are in danger of being blocked by Baidu. It is best not to exchange links with them, such as pages with obvious keyword stuffing, private server sites, etc. wait.
2. Use jump links instead of direct URL links: In many online self-service friendly link systems, their friendly links do not directly point to the partner website, but link to a page of their own, through which they jump to other websites. For websites, most of this method is to monitor the number of clicks of friendly links. However, this method may cause risks to the cooperative websites. Firstly, the quality of the links is not as good as direct links. Secondly, if 301 jumps are not used, May cause unnecessary trouble in search engine rankings. Therefore, if you encounter such a website, the webmaster must strive to use direct links instead of jump links.
3. The link code is outside of HTML: A normal web page starts with the [html] tag and ends with the [html] tag, forming a complete web page. However, it is currently found that some webmasters write the link code outside the [html] end tag. Since [html] represents the end of a page, if the link code is written in [html], there is no guarantee that the link will be recognized by search engines. Normal crawling, this situation also requires us to be careful when making links.
4. Too many exported links on the page: Google clearly recommends in its guidelines to webmasters that webmasters limit the number of exported links on the page to less than 100. Too many exported links will dilute the weight and PR delivered by the page, thus To reduce the meaning of friendly links, take PR as an example. If a page with PR5 has only 1 external link, then the PR passed may be 5. If there are 100 external links, the PR passed may be only 0.05 or even Less, the calculation of PR is not as simple as above, but one principle is known, the more external links, the less PR will be allocated. This requires our webmasters to not just look at the PR itself when making links, but also comprehensively consider the number of external links on the page.
5. PR deception: Let me tell you a case. One day, a website with the domain name peopledaily.com.cn suddenly came to exchange links. The PR was 6. However, as an SEO site, the domain name was obtained like this. It was strange and inevitably made people suspicious. At first I thought it was PR hijacking, so I checked the registration time on whois and found that the registration time was still very long. Later, I searched this website on Baidu and found that the predecessor of this website was for photography. It was well-known in China, and its PR was so high. But for some unknown reason, the domain name was bought and a new website was built, but the PR was not updated in time. Due to the change of the website theme, the PR of such a website will not last long and is likely to be cleared in the next update cycle. Therefore, when encountering a website with a PR that is too high, it is recommended that you conduct two checks. First, check the registration time. If the PR is too short, it may be PR hijacking. Secondly, check the source of the external links of the website to see if it has the same theme as the current site to prevent Being deceived.
Finally, I hope that all webmasters will exchange friendly links with an honest heart.
