When the word hidden link is mentioned, my friends who want to be SEOs should easily think of the concept of cheating. Yes, because hidden links are a common method of SEO cheating. There is also another related term, which is hidden text. , in fact, this is similar to the concept of hidden links, except that there are no links in the hidden text. These are things that our users cannot see on the web page, but search spiders can, which is why these words and links are included. The fundamental reason for hiding is not to be seen by users but to be discovered by search engines. If the method is used properly, it can be considered effective.
Although hidden links are expressly prohibited for search engines, as the saying goes, nothing will be perfect, and the same is true for search engines. Although the penalty mechanism is formulated by him, since it is a rule, it must be There are loopholes to exploit, and if you use hidden links well, you can also exploit loopholes, and naturally you can make a lot of profits. Therefore, in this article, Xiao Jun will take a more comprehensive look at the definition and manifestation of hidden links.
Why hide links?
Since you want to hide links, you naturally don’t want them to be seen in the light, and hidden links are a common cheating method in SEO. It can be understood that this is an act of deceiving users. Users cannot see it in the front desk of the website, they can only view it. You can only see the source code, but when we look at the web page, should we look directly at the front desk or the source code? It is conceivable that this can also be regarded as a cheating behavior without affecting the user experience, because these links can be seen by search engines Yes, and it can be indexed for weight distribution, but cheating is cheating, and once it is discovered that the K station will be demoted, there will be no discussion.
Common forms of hidden links
1. Hang a black chain. This is a relatively common method of hiding links. It cannot be seen by the front desk of the website. It can only be discovered by viewing the source code. It is usually hidden with CSS, and JS can also be used to output CSS. Moreover, the harm of this kind of link is also very fast. Big, because I have encountered some websites. Not only that, but also an industry has been formed invisibly. For example, some people are engaged in server management, and there are a large number of sites on the server. Then this is a very powerful resource at this time. , especially when there are high-weight websites, high PR stations or even educational ZF websites on the server, because these are high-quality single links, obtaining single links is an important project for the external link strategy. So if one day you see a PR6 or PR7 site suddenly exchange links with your PR2 site, if the other party’s PR is not hijacked, it may be easy to find out that the author is a black link. Of course, this also shows that his Black Chain has been relatively successful.
2. Links with the same color as the page background. It may be easy to understand this point by using hidden text, that is, the text color is the same as the page background color, which can be seen by viewing the source code, and of course it can also be seen by selecting all. For example, if you display white text on a white background, the same goes for hiding links, but you need to set it up slightly.
3. Links that are too small to be discovered. For example, in the content, set the text link in a space or a hyphen in a very small font, so that we can't notice its existence at a glance. In fact, it is somewhat similar to the second point, except that this is not setting the color.
4. Links that are the same as the surrounding text. This may be difficult to understand. To put it simply, it is not obvious which link is in your content. For example, we usually set link styles for text links, such as setting anchor text colors and underlining text links to highlight the text. Links make it easy for users to identify links. If these styles are removed, the text links will look exactly the same as other normal text. Users will not be able to recognize that this is a link unless they put the mouse over it.
In fact, the first three points are easy to understand. The fourth point may be ignored by more people. In fact, from the perspective of user experience of search engines, anything that goes against the user experience is bad, including what users cannot see. Links, so we must pay attention to this in future link construction: links that users cannot see are hidden links.
I feel that these points cannot fully summarize the concept of hidden links. Everyone is welcome to communicate and discuss, so that we can better understand this method and expression, so that we can have a deeper understanding of some of the mechanisms of search engines.
