At ordinary times we do website SEO, may often talk about a topic is the external link, we will focus on the work of the construction of external links, but hidden links for everyone may be the first to hear, it refers to the unusual URL link, but the Web page is missing such a link, Because the need to call pictures, CSS styles, JS scripts, etc. need to be implemented through hidden links, but these links are not visible in the page anchor text links, so called Hidden links.

So far, everyone has been observing and studying, look at the hidden link to the bottom of the rankings and the impact of the weight of the site, although there is no obvious argument, but we can from the search engine performance, as well as day-to-day behavior to objectively analyze the hidden links in the future can affect the site keyword rankings. Before you start the analysis, you should first summarize the general hidden links.

Hide different categories of links

Common hidden links have the following several aspects, picture links, such as common pictures hotlinking, site A using B's picture, then the domain name of b is a hidden link; JS and CSS links, the general JS links are links in the station, but also does not rule out the call JS outside the link, whether the station or outside the station, this is actually a hidden link; e-mail links in e-mail, if there is a link exists, then the search engine will see that this is also a common hidden link; RSS Feed link, now many use RSS to subscribe to their favorite content, then the seed is not a valid external link? Especially for the blog, after the login link, some sites need to log in to see the content, and the content of the link will be search engines as a link? Baidu related domain, Directly appear in the Web site, is commonly known as Baidu related domain, such links have a role? Flash links, as we all know, the search engine on the content of Flash is not friendly, but the link will be? A link in a form in which the data in the form is the user's interaction, and whether the link in it affects the ranking ? Advertising Alliance links, ad league links, Google AdWords point to the link is considered as part of the algorithm?

Search engine's Multiplex link relation

After you know the hidden links above, the key point to share is whether the links will be counted as part of the calculation weight. Personally feel that some of these links will certainly play a role in the rankings, first, with the development of the Internet, more and more cheating methods are used, so search engines need more ways to judge the relevance of the site, the need for a wide range of links, so it is likely to use user behavior, such as form data, email in the data , the data in the RSS seed and the number of times that the Baidu related domain appeared, these and user behavior has a very close relationship, in addition to the links appearing in SNS, these are users of the daily talk of the link, with the social network of SNS explosive development, the search engine is likely to gradually take these as a basis.

Googel tracking links in different places

In addition to the above points, Googel has also been trying to read and trace in different places in the URL link, such as Gmail appears in the link will generally be Google tracking, in general, click on the link inside, you will first see the tracking link, and then the real URL path, In addition to security, Google is likely to do so is to pave the way for future rankings and preparation. In addition, the search engine is not to see the picture, but the search engine will go to acquire specialized image recognition processing companies, in the picture color, type, facial similarity and so have new progress, so later for the image processing will certainly have a new breakthrough.

The external link is we do seo cliché problem, the search engine's core algorithm is also relies on the external link to a large extent, but the external link is more and more diverse the time, the search engine certainly will continue to enlarge the original core algorithm, the mainstream user often goes to the place, often discusses the question to consider, This is not only the user's Internet environment changes, but also the gradual changes in search engines.
