Summary: The site down the right obvious performance is the drop in keyword rankings as well as the site from the search engine to get the flow down. 1, Query site collection (site: down the right of the website) (1) to see if there is no drop in the number of search engines, the site included in the number of declines
Site down the right obvious performance is the drop in keyword rankings as well as the site from the search engine to get the traffic down.
1, query the site included (site: down the right of the website)
(1) See if there is any decrease in the number of included Web site in the search engine, included in the number of drops is not necessarily down right when the right to drop may be due to include, if the included no change is not due to the path of the reasons for the change, if the decline should pay attention to the site has been revised, the path has not changed, If the program changes the path must also change.
(2) Click on the query included some of the path is valid, the purpose is to see if there is a dead link, if there is a dead link to be checked, these dead links are from the directory, a large number or less, so you can determine whether the death of the link caused by the right to drop.
(3) Whether the content is included, repeat the title and duplicate content page, if included then the reason for the right to fall can be determined.
(4) You can view the collected frequency (refers to the number of 24 hours included), a lot of site traffic is even if the traffic, such as some news and information classes of the site if they send the article does not grace it the search engine immediately released, so the flow is going to fall very quickly, because most keywords are clock and get traffic.
2, query Baidu related fields, only check the first 10 pages of the relevant domain page
(1) Click to include blog and forum Path Point (the first 10 pages). See if there is a dead link, if a lot of dead links may be his blog or the Forum personality signature was deleted, perhaps to delete an article, or his account was deleted by the platform site, which will lead to a large number of links lost and lead to decline in keyword rankings.
(2) See Baidu related domain there is no spam links, the proportion of spam is burned, and then calculate the first 10 pages related to the proportion of the relevant field, if the proportion of more, then may be caused by the garbage link to the site down right
3, search attentive contrast
(1) Observe a search engine of the same industry site, to see whether the right to fall is a universal phenomenon
If the industry is most of the site has been down the right, then the search engine algorithm has changed, we have to institute the right to drop the public law of the site, such as (this is a hypothetical analysis) "is not to do the Forum personality signature for the chain of the site down right?" If it means that the search engine has lowered the weight of the personality signature ratio, We just need to find the common rules of a sound web site.
(2) Comparison of different search engines
Compare the rankings between Baidu and Google's two search engines, if Baidu's ranking drops, Google's ranking also dropped, according to the 2 included also dropped, then it may be because the server out of the problem, resulting in the site instability, page opening speed is slow, so we just need to solve the stability of the space on the line.
(3) is not a new station
New station can be used webmaster tools to query can be judged, included a lower value, there is no PR value, is not using the old domain name, this old domain name has no right to drop, before the domain name to do the industry and now the same industry, if it is a new station then classified to the new station phenomenon, there are some unique new stations will lead to decline in rankings, Links increase too fast, template changes, and so on.
