Exchanging friendly links is also one of the work contents of SEO work. Maybe many SEO friends know the skills of exchanging friendly links. They should look at the information of the other party's site, and then combine it with their own site conditions to decide whether to exchange. Yes, the usual process of exchanging friendly links is like this, but have you ever considered that sometimes the information you see on the other party's site may be fake and deceive you? Let’s talk about a summary of the deception methods I encountered when exchanging friendly links.
1. True and false PR value
When we exchange friendly links, what we observe on the homepage is the PR value of the other party's site. Although everyone has different opinions on the role of PR value, no one will refuse links from high PR sites. Some people do. Seize this point, use hijacking technology to hijack the PR of the site, turn it into a high PR site, and then link to you. I have encountered such a thing. The other party used a site with PR5 to link to my site with PR3. At that time, I saw that the site's PR was relatively high, so I linked to it without thinking too much. Just when I was happy, my colleagues poured cold water on me. It turned out that the real PR of this site was 1, and the PR value of 5 was hijacked through PR. At that time, I was still puzzled. This was really hard to prevent.
Solution:
Method 1: We all know that PR is a product of Google, so we can judge it through Google; you search the domain name of the other party's site through Google and see if the number one in the search results is consistent with the other party's site. If it is consistent, it means If it is true, it is false. What you need to remember here is that when searching for a domain name, you must enter both the one with www and the one without www.
Method 2: You can query through http://checkpagerank.net . When you enter the domain name you want to query, if it prompts "Pagerank is valid" below, it means that the PR is valid, and the PR value of such a website is true. PR. If "Pagerank seems to be forged" appears below, it means that the PR of the domain name is fake. The fake PR is achieved by forwarding sites with high PR values, which is what we call hijacking PR.
2. The other site uses JS script to redirect
This is something I encountered when I was doing SEO for less than 2 months. At that time, I didn’t know much about the steps of using JS. In fact, this method can be said to be easy to see through and not easy to see through. The key lies in whether you carefully check the other party's site. The JS script code can be seen in the source file. If you check carefully, you can see the clues. Check Those who are not careful will naturally be fooled by it.
Solution: When checking the other party's site, check the source files of the other party's site. If you find the JS call script, see if the JS script turns to high PR. If so, it is a fake PR.
3. Use the nofollow attribute
Many forums now talk about the nofollow attribute, which means that the link is invalid. When the site you link to has this attribute, you can give it a lesson. This attribute is not helpful to you.
Solution: Check whether the other party's site contains the nofollow attribute definition after the link. If so, you can remove such a link, which has no meaning to you.
4. Generate static camouflage method
When exchanging friendly links, we often encounter domain name suffixes of index.html and index.asp. Among them, .html is the default first suffix of the server, but .asp is not, so when exchanging links, a If you don't pay attention, you will link with the .asp suffix. Such a link can only be said to be a one-way link you made for the other party.
Solution: When exchanging friendly links, carefully check the suffix of the other party's URL. If the suffix is .asp, there is no need to exchange it.
5. Forwarded friendly links
This is what I encountered recently. I can only say that this is really hard to guard against. What it does is that the other site forwards it through the system. In fact, this link is not directly linked to each other, but linked to you through a redirect link within the site. But the final click will lead you to this page, but for the homepage of a website, it is not helpful at all, but will drag down the weight of your own site.
Solution: When checking the other party's link, look clearly at the redirection problem of the domain name. If there is a redirection within the site, please suspend your exchange plan.
6. Set robots.txt to prohibit friendly links
Many people may not pay attention to this, but it actually exists. In the sites that provide friendly links to you, they use robots.txt to disable their own friendly links. The purpose of this is to make your link become theirs. One-way links, but your site does not have any external links.
Solution: You can check the other party's robots.txt settings to determine whether it contains the function of prohibiting friendly links. Just add /robots.txt after the address of the other party’s homepage to view it.
7. Replace the entire site with a single page
This is also a problem that many people don’t often pay attention to. Nowadays, some websites usually go through an entrance and then reach the display area of friendly links. However, this entrance only exists on the homepage but not on the inner pages. That means this is a single page. Page links; the other is site links, which not only appear on the home page, but also have the entrance to the friendly link display area on the inner pages. This is a link to the entire site. Sometimes we often replace the friendly links of other people's single pages on the entire site, and the weight of doing so is very low.
Solution: Pay attention to check the difference between the other party's site and your own site. If we are using a single-page friendly link method, then we can remind the other party before linking when changing the link; if we are saying that we are using a whole-site friendly link method, then We check each other's site that way, such as a single page then we should be careful about exchanges.
The above seven points are all methods of defrauding friendly links that are not easy to see from the surface. I hope it can attract everyone's attention and help everyone not to be deceived when exchanging friendly links.
