There are a lot of times we exchange links will appear in such a situation: is today added a few chain took a few three days or less time the ranking of the site fell, the flow has dropped significantly, thinking of looking for a large circle only to find the reason is earlier changed a few have the problem of the link! Imagine how important it is to switch links, So be careful!

In theory, the more link resources the better, because it will leave the search engine is very popular impression of the site. But links are not all that can be, such as hidden links, or even illegal messages. Such an abnormal link not only to enhance the weight of the site does not help, but it is likely to suffer from the search engine penalties. Even the canonical link is to be fastidious about the quality of the link. Because now the main way to get high-quality links, mostly through friendship exchange. If you export your site to export the target link site is too low, or suffer from the search engine penalty site, as can not effectively enhance the weight, there is the risk of joint punishment.

One, the site snapshot update slow

Site Snapshots Absolute site weight changes in the radar, content rich and often keep updating, will attract frequent search spiders, the same will bring frequent updates to the site snapshots. There is also a rich chain of resources, and a balanced increase in the chain of resources of the site, will also attract frequent search spiders visit the site, the corresponding site snapshots can be updated frequently. Site Snapshot date stalled, indicating that the site has slowly been overlooked by search engines. Site snapshot back, then at least from the site after the appearance of the date of the start, the search engine that this period of time, the site has been abnormal optimization methods. In the exchange of links, the site snapshot date is an object that has to be considered, the site has not been updated for a long time, the weight of its web site is generally not high.

Second, the number of content included less

Included a small number, said the site does not have much content. If the content of the site is very rich, but the content is as small as possible, it is serious to explain another problem. That is, the quality of the site content does not seem to be more rich in fact, more than copying to copy, or some of the false original. and the quality of the site is based on a wealth of high-quality content, a Web site by the search engine contains more content, indicating that the search engine has a high degree of recognition. In general, a Web site included in the amount of not even 100, the weight of the site is no higher than where to go. Therefore, the collection of low number of sites as far as possible not to exchange links.

Third, link export site more

Google PR Value Calculation formula, there is a PR input value concept. For example, the PR value of a website is 4, Exchange 10 Web site input value is 2, Exchange 20 site its output value may become 1.5, of course, there is a link to the weight of the resource site. The specific PR output value formula, we do not go to explore also has no practical significance, we need to know that the existence of this fact. In fact, not only Google, Baidu and other search engines also have a similar weight input calculation method. With the link to export a number of Web site exchange links, if the weight is much higher than their own site is OK, if the weight is quite even lower than their own site, there is no meaning.

Four, the page loading speed is slow

Do not think that after the export link, the quality of the target site is not related to their own, the quality of the target site will affect their own site. such as illegal websites, such as dead chains and very slow loading sites. Because search spiders are set the crawl time is limited, more than the established time will give up, so that the search engine can crawl without links, reducing its efficiency. In addition to the slow loading of the site, unstable sites often down in the virus Trojan in the site, the same will be adversely affected. Exchange links, you may wish to comprehensively test the target site's access speed is extremely stable.

Five, the core words ranked Low

For website construction and site optimization, low ranking means that the site in the target search engine weight is not high. For example, we and a website Exchange "website construction" This keyword link, and the other site this keyword ranking even in hundreds of, is exchanged, to enhance the weight also has no meaning. It should be said that the core keywords ranked in the top 100 of the site, its weight will not be low, the extension of the long tail word ranking are more ideal. Keywords in the search engine in the ranking, is the most direct and most important site weight performance, but also affect the quality of the exchange of links. Exchange links, of course, the target site's core keywords ranking the better.

Vi. Optimizing Excessive trace weight

In search engines, it is cheating to be overly optimized. In the site optimization problem, search engine actually love and hate. Love is because the formal optimization is based on the quality of the site itself on the basis of continuous improvement, such as continuously enrich the content of the site, such as the speed of the site to improve the pace, and constantly optimize the profile code. There are two reasons to hate, because the nonstandard optimization has seriously interfered with the search engine on the weight of the site, especially the use of Heimao cheat methods to optimize the site; Hate the second reason is the search engine itself, if most of the Web site is optimized by the way the rankings do up, So who's going to buy search engine ads? So relatively, search engines prefer to optimize traces of shallow, even no traces of the site.
