In how to interpret the information given by the search engine, we discussed the value of the link, that is, no matter from which point of view you can understand the information given by any search engine, will come to the "value of the link is different" and so on, of course, it is also known, Perhaps each SEO slightly understand the person can like recite the Bible to say "the link from the authoritative website is more valuable", "has the relevance link value is bigger" and so on, but this kind of guidance opinion how applies to the daily SEO work may not be so clear, For example, how can we tell if a website is authoritative? How do I determine the relevance of a link? And more importantly, even though we can have our own conclusions, does the search engine think so? Are the authoritative websites we judged to be spam or worthless sites by search engines? Many times, limited by the position, the angle of the relationship, from the search engine perspective to consider SEO is not so simple.

In the most basic sense, any links that are easily accessible without a threshold or a high threshold for almost anyone mastering certain techniques and methods are certainly of little value, which is why the links from fees and audits of relatively stringent Yahoo! directories and free DMOZ directories are valued by many. Although some people have also questioned Dmoz, such as randfish that "tightly ' re not a perfect choice", because in order to join DMOZ and have to "bribing editors"-we encounter the situation is known as DMOZ editors to " Bribery "-but in any case, the value is still undeniable is recognized.

However, for most of our websites, the source of the link is always limited, its authority is not so clear, how to find a valuable link is SEO implementation of the main problem. In this article, we simply consider from another point of view, the value of which links (which only involve the source of the link but not the anchor text) in the search engine's view, or, more precisely, how to determine which links are not helpful or significant for improving the final ranking of the site in search engines?

Exchange links

Exchange links This kind of simple "you link me i link you" way, does not need too much skill, is widely used in many websites. But objectively, the value of the linked link is simply not guaranteed, especially for the "Swap link pages" that are set up on many sites-originally intended to accommodate more exchange links.

From the point of view of the search engine, let's not talk about the problem of two-way links, it is easy to determine the "intent" of such a page, the page and the link down the page right. At the same time, the links in such pages are often the standard high-density keyword links-believe that most sites in the establishment of exchange links will require the other site to use their own choice of anchor Text, to embed the site SEO targeted keywords-and this is in itself to draw the search engine vigilance signal.

Quality of other links on the page

The value of a link is also related to the quality of other links on the same page. The value of these links in turn determines how the search engine views the quality of the entire page and the links to your site that are contained in the page. If most of the other links in a Web page point to a spam site, how can you expect the search engine to look at your "brother" site?

The typical example is the "Exchange Link Page" above, which is the main reason why I am not always optimistic about the exchange links. Of course, switching links can be acceptable in some cases, from a more than nothing perspective.

Station Group

The use of station groups for SEO or "search engine optimization" The oldest means is still valid in many cases, this is our recognition, in fact, many SEO enterprises to be proud of the "resources" in many ways is a metaphor has a huge station group, of course, The results of the final measurement are often how many links can be built for them within x days, but it must be clear that the value of links between stations has a tendency to "shrink" or even bring negative effects.

From the point of view of the search engine, the judgment of the station group is not as simple as some people think, whether there is a connection between the domain name registration information, host IP and so on is only the first step of its judgment, other related also includes:

Is there duplication of content? Do you have the same or approximate appearance and page design? Is there a cross link? This is the inevitable, but also the establishment of the station group purpose!

Do you have the same or approximate inverse link? Or is it that the PR of multiple sites in the station group is delivered by the same website? This is also almost inevitable, it is clear that if there are many sites can get enough from different sites from the link, perhaps there is no need to play the station group.

Finally, more importantly, the station group in each small site "intent", is it for users or search engines? Although I believe that the vast majority of sites used for SEO site will be declared the purpose of the station group is to better serve users, but, here said "Inetnt" is not your own claim or believe that "intent", but the search engine that "intent."

New sites with insufficient links

In contrast, the enthusiasm of the new site is always the highest, especially from the point of view of the exchange links, so there is little obstacle to exchanging links with new sites or getting links to new sites in other ways. But what must be seen is that the search engine always has a certain skepticism about the new site, it is always "reserved" for its own value and the value of its links before it confirms its credibility, and the new site proves itself to be more than just an effective content-building, an extension, and a time to validate Time is one of the most effective judgment factors. Station. Long Station

In addition, the problem with the new website is that its access to most of the links are not high quality, such as from the low value of the site links accounted for a large proportion, such as most of the links from the same site or from multiple sites, but these sites have been identified by search engines as a station group, and so on, these are very clear signal of untrusted trust

Of course, this is not to deny the value of the new site, after all, any towering trees in the early days are weak seedlings, but that the new site needs to prove its own value, and before they prove their value, the link from it may not have the value you think so much.

These are just a few examples of low value links, and many other types of links will not help your SEO, unless you think you can use the link quantity instead of quality to win in SEO.
