The role of friend link exchange in website optimization is self-evident. It can be said that Baidu's optimization algorithm is largely based on friend links. When many high-quality links recommend a certain website, This website will undoubtedly be considered by Baidu as a website that is of great help to users. Improving the ranking of this website is a matter of course! So now there are professions dedicated to exchanging links!
However, the exchange of friend links is not always smooth sailing, especially now that the exchange of friend links has reached an era where deception is prevalent. Many webmasters will become victims if they are not careful, and many webmasters become victims without knowing it. In fact, It is a very regrettable thing. For this reason, the author summarizes the following five common friend link scams. I hope that the majority of webmaster friends can have a pair of discerning eyes in the process of friend link exchange and avoid the risks of these friend link traps!
1: After exchanging friend links, delete them after a period of time
This method is the most primitive and lowest level of deception. After all, it can be seen through by others at a glance. However, this method occupies a very important position among many friend chain deception methods. The main reason is that it is simple to operate. The other is After the friend link is passed, many webmasters will not make a return visit. If the return visit is only in the first few days and there are no problems, it is easy to ignore it. It is these scammers who take advantage of the weaknesses of human nature and often succeed in deceiving through this simple method. Therefore, for us webmasters, it is very simple to avoid this risk of deception, just make return visits every now and then!
2: iframe frame cheating link method
This method is almost no longer used, especially due to the upgrade of many website building program versions. In addition, the framework program itself is not conducive to search engine optimization. The original popular iframe framework website construction program is almost rare, so through this method The possibility of defrauding links is also reduced. After all, it is not conducive to the optimization of your own website! In addition, this deception method can also be easily checked through webmaster tools, so the value of using this iframe to deceive is not high, but It’s also useful for webmaster friends to know about it!
Three: Use js script to call deception
Nowadays, search engines have no way to recognize the text in JS scripts, and these texts can also be made into hyperlinks. In this way, many people with ulterior motives have paid attention to JS and madly exchange friend links with others without losing their own weight. It also brings profits to the website, and more importantly, it can guide the weight of other people's websites. It can be said that it kills multiple birds with one stone. Moreover, many webmaster tools have not been able to detect this deception method. After all, JS is an indispensable language for websites! So this has now become the mainstream of friend link exchange deception methods. The only way for webmasters to crack it is to simulate crawling through spider programs! Or just look at the snapshot of the website!
Four: Add the nofollow attribute in front of the friend link
This method is similar to the JS script deception method. The only difference is that one is set through attributes, and the other is not included by search engines through language. Adding nofollow in front of the friend link means telling the search engine not to include the page content exported by this link. , which means that the weight of your website cannot be transferred to the friendly links under the nofollow tag, and there is currently no webmaster tool that can crack this method. The only way is to look at the source code of the website to see if there is anything in the source code. nofollow!
Five: Use programs to block spider IPs to access friendly links
This method is currently the most covert and requires a relatively high technical content. There is currently no good way to identify it, let alone webmaster tools. If webmasters want to solve this deception, they can only do so by viewing Baidu snapshots. Find clues! And also have considerable understanding of search engines!
All in all, naturally there will be cheating when there is profit, and there will be cracks when there is cheating, and there will be newer cheating methods when there are cracks, and this cycle goes on and on, but no matter how the friend links cheat, evil will prevail over good in the end, just like website security. Where there are production Trojans, there are Trojan killings! For us webmasters, when exchanging friend links with others, we should also be more cautious. The so-called guarding against others is indispensable, and the intention of harming others is indispensable!
