In the process of website optimization, exchange links is one of the most important part of a lot of people in the exchange of links when the most concern is the other side of the PR value, must find a higher than their own site or at least have the equivalent of the PR value of the site to exchange, I believe that the people who hold this view and a few, However, as a professional provider of Web site optimization services, our technical experts to share some information on the friends of the exchange of unconventional reference points.

Check each other's website indicators

One, the weight (google Google pr value)

Nonsense not to say, now a lot of platforms or QQ group is to the other side of the PR value is more than equal to how much? We cannot help saying that the weight of links in search engines is diminishing today, which is one of the most primitive practices (albeit more effective), Simply on the optimization we should pay attention to the PR value of the export weight is not a site weight, a weight of 5, export weight is 0.1 of the site with this weight is 1, export weight is 0.5 of the site, as the author to exchange with the latter, figure below:

Case Site Export Weights

163 News channel Export weights

Recommendation: Do not focus on each other's website overall weight, the real export weight is the key.

Second, Baidu snapshot

For Baidu snapshots, there are people who simply use the site command to see the other top-level domain name or the WWW domain name Snapshot update date (someone can withstand three days, someone can withstand 7 days), I do not object to this reference indicator, but as we better focus on removing the snapshots of the home page outside the snapshot, the following figure:

Case site Baidu Snapshot situation

The above picture we can see, for this site, the home page snapshot is not normal, but you can see all the snapshots of the internal pages are relatively new (PS: This site is my friend, the first page is all JS call, so the snapshot is not normal).

Suggestion: Take care of the home page, but also to see the pages, because the weight of the home page is accumulated, all attention to the snapshot of the time may wish to refer to the other site of the other pages included in the snapshot update index.

Iii. included quantity

We are accustomed to check the amount of each other's collection, seemingly included in the number of the more the better, but I think, included to see the long-term, look at stability, with some query tools to pay attention to the other site's collection of historical records, for the collection of data with the regular site type is not very coordinated (for example, for the number of corporate sites included hundreds of thousands of), Historical data of sudden rise and fall of the situation to pay special attention (may have been, or will be the search engine K), the following figure illustrates:

Case site History revenue record

Recommendations: With the site size, type matching, with a stable collection of historical site indicators is more perfect, but also more reference.

Time is limited, other points will be shared in the next chapter, this is opinion, do not like or do not agree with the brick, agree to welcome everyone reprint: Zhengzhou website optimization, http://www.371518.cn/article/show/64.aspx
