In the process of website construction and website optimization, friendly links are a double-edged sword. On the one hand, normal exchange of links can indeed be mutually beneficial and mutually improve the ranking of specific keywords in search engines. On the other hand, links will also be affected by the downgrade of the exchange party's website. Although it is called a friendly link, there are still many pitfalls in link exchange, which is also a problem that is often encountered. Link cheating is despised by everyone, but because it can achieve one-way links and quickly accumulate website weight, many people still use it secretly. This is undoubtedly unfair to the party who was deceived. The purpose of exchanging links is to increase the weight of the website. Not only does this fail to increase the weight, but the weight of the website continues to lose because there is only output but no import. There is no way to prevent link spoofing, but there is definitely a way to identify it. It’s just that today’s cheating methods are becoming more and more confusing and require a very sharp eye.
Scam 1: Link deleted after exchange Difficulty of identification: ★☆☆☆☆
This method is very simple to operate and easy to identify. That is, after exchanging the connection, the link is deleted unilaterally without the other party's knowledge. Since search engines have certain requirements for the stability of exported links, and they can be viewed through webmaster tools or by opening the website, not many people actually use this method to defraud links. What's more, when the website runs unstable or suffers from a downgrade, the link is more likely to be removed. Whether intentionally or unintentionally, it is not a good thing if a link is deleted. What we need to do is to check the website frequently and deal with the problems immediately if we find them. No one wants the website that exchanges links to be penalized and downgraded, and the website they have worked so hard to run will be implicated. Therefore, the best way to ensure stable links is to ensure the safe and stable operation of the website and continuously improve the weight of the own website.
Scam 2: Embedding iframe, difficulty of identification: ★★☆☆☆
Iframes are also links. They just embed low-weighted page links into high-weighted pages (usually the homepage of the website) to defraud higher-weighted links. When link exchange just started, Iframe was used by some people with ulterior motives, but now it can be recognized by general webmaster tools, and the frame technology is not friendly to search engines, and is not conducive to website optimization and authority improvement, so now through this Those who used this method to defraud links have almost disappeared. However, after exchanging links, the iframe method of spoofing links still cannot be underestimated. It should be pointed out that apart from looking at the code, it is not easy to identify iframe links with the naked eye. Making good use of webmaster tools is a good way.
Scam 3: Using JS links, identification difficulty: ★★★☆☆
Because the current search technology cannot recognize the text in JS, many people have made crooked ideas on the links. In addition, some webmasters are not proficient in programs. If the script is classified to hide the call, the JS link will be quite deceptive. On the surface, there is no difference between a JS link and a normal link. The link can be opened in the same way. Due to the non-iframe page call, some webmaster tools do not even list it as a prohibited object. However, search engines cannot recognize JS programs, and the content in JS tags cannot be recognized. Such links will not help improve the weight of the website. The best way to identify JS is to use a simulated spider program to view crawlable page content, or directly view website snapshots.
Scam 4: Add Nofollow links, identification difficulty: ★★★★☆
The Nofollow tag is quite deceptive because some webmaster tools cannot recognize it and search engines still include the current page. In addition to adding the nofollow tag to the <meta> tag to deny inclusion by search engines, the link <a herf="***" rel="nofollow"></a> tag is also quite destructive, telling search engines not to include it. This link exports the content of the page. The best way to identify nofollow link deception is to view the page source code. There are also some webmaster tools that can identify nofollow. Although it is not fully supported, it is easier than viewing the code line by line. If you find that nofollow is used in a link exchange, you should immediately remove the other party's link. You must not be merciful to deceive links with malicious behavior.
Scam 5: Block search spider IP, identification difficulty: ★★★★★
This is a new type of link cheating method, and it is also the most difficult cheating method to identify so far. Almost all webmaster tools cannot identify it. The method of operation is to block the IP address of search engine crawling spiders. When search spiders crawl the website, the link content is automatically hidden through the program. In this way, all the links exchanged are imported unilaterally, and they are all keyword anchor text, so the link quality is naturally unparalleled. It is said that Langyu’s website used this method and exchanged more than 400 high-quality links (it is just an Internet rumor, it is impossible to distinguish whether it is true or false, it is for reference only). However, I have indeed encountered this method of deceiving links, and just a few days ago, a strange friend sent a QQ message to remind us that there was a problem with a link we exchanged. We compared the query results of the webmaster tool through Baidu snapshot query, and it turned out to be the same. said. Currently, the only effective way to identify such fraudulent links is to view page snapshots.
The truth is as high as the devil, and link cheating seems to be a bit more evil than good. Simple link cheats such as deleting links and embedding iframes are no longer common, and have been replaced by more deceptive cheating methods such as automatically blocking links based on search spider IP addresses. But even so, as long as we pay a little attention, it is not impossible to identify it. Professional website construction company Pilot Technology ( www.joyweb.net.cn ) also believes that there is no permanent way to eliminate link cheating. Although it is difficult to nip it in the bud, it is not too late to remedy the situation. Although link exchange has various disadvantages, it is very important for improving the weight of the website. You can only proceed with caution and don't give up on it.
