Mature the webmaster all know the benefits of link exchange.Link is to attract the spider and transfer the weight of effective techniques, is a kind of high quality outside the chain.But the chain is never exchange with them?Those links can't exchange?The chain is pit dad?Webmaster to eat to much bitter today.Be a baidu retracement of chain harm not light.Fortunately, timely remove chain.Rankings are restored.
The most can't exchange friend chain ten kinds of circumstances:
First: the snapshot is not normal.A snapshot is to check the site overall performance is one of the best data.Snapshot is best the next day, three days a snapshot of The Times.If more than 7 days, or even a snapshot is a long time before standing, then you had better not exchanged, of course, we don't do to snapshot too stringent requirements, take 6.28 baidu K station events, many regular high weight site possible snapshot is not normal situation.There is a kind of situation, a snapshot to stop.Normal.This kind of stand you to look at his weight and flow rate.If it is large.You can continue to link.If the dispensable.Off immediately.Lao tze today is to eat the loss that ya.Themselves..
The second: don't cross links.Unless you have this aspect of the requirements, otherwise the author is to stay don't suggest you do this link.New stations can buy short-term ranking ascension and flow on this.Stable later.Waiting to be K.So friend chain IP must be registered in a timely manner.If your site has a lot of cross links, it is easy to search engine found, station group and think you are doing, or buying links.The effects of the you know.For this, the author's suggestion is that using EXCEL documents, make it a link record sheet, as shown in the figure below, the website construction in shenzhen can record a clear chain of friends to exchange information.
Third: it is best not to do inside pages link.This is not absolute, if the other site of the inside pages of the weight is very high, also can consider, if the other side of the pages related to the site at the same time, weight and so on as you, so even if the other party say more nice, milan beibei don't suggest you to exchange.
Fourth: cheat friends with js code chain jerk.This is a lot of friends in link.Check the party we can put the mouse as for the other site friend chain, look at the address on the state whether jump address, at the same time, we can look at the site page code, see if there is a jump code, as shown in the figure below.Put an end to the situation of the method is look at the other side of the source code.
Fifth: the chain too many links.Own use tools to check the PR output values.According to the principle of the cake.The more people, the less you get.Even if the weight of each other is 9.But he has hundreds of links.According to the formula: Google PR PR = d + (a) (1 - d) * (web page PR value of the a/a export link) +...(1 - d) * (web page PR value of N/N export link).According to this formula, you passed by weight from this site few and far between, we in the exchange of friendly chain, how high is not just focus on each other's weight, import links often influence is greater.
Sixth: see whether with nofollow.Nofollow tags to do optimization should know the usefulness of it.He will stop the spider to track, and at the same time to prevent weight transfer.Query method is very simple, as long as we open each other directly site page source file, see the nofollow thing.Of course, also don't have change, can change if it is a high traffic site, although the labels, but it also can bring certain traffic to our site.As we know that baidu experience outside the chain have nofollow tags, but baidu experience of traffic outside the chain can be very good for us, we can also be appropriate construction
Seven: see whether robots with rules limit.Concrete example is shown in the diagram below, we know that robots files can block search engine spiders, if robots will have blocked the links page, that link you change is in gave him a unidirectional links.Of course, if you are to get certain traffic, also can be exchanged.Detail your adsense personal grasp.
Eighth: unfavorable exchange link frame frame structure.Frame structure is now rarely used, but it is not absolutely nobody use, this kind of structure to the search engine is very unfriendly.Is to pay attention to the exchange.
ninth: unfavorable exchange not related industry links.Current search engine algorithm is very intelligent, and search engine is more pay attention to the relevance of links, if the other side of the website and your website is not related, so the quality of the links will be discounted.This no more.Of course want to close.Is the opinion.Milan beibei think will lead to traffic.Is a good site.View the data every day.His master.
Tenth: snapshot back to file links.The hole is.Back to the archives is the baidu had a cow.Before 10000.Back to the archives, 5000.This kind of site.Our own can be said to be cheating or violations.And then be slightly punished.So.Find this kind of situation.Don't be exchanged.Posting the original yourself.
Or that sentence.Outside the chain is king.Content is king.Absolutely original content.Is our stable survival.Speak so much today.The research subjects other next time.
