Advance of the website how many time, forces and money for it were not spent, can be inefficient. The problem consists in filters which impose search engines. Their existence is not always obvious therefore additional check is required.
The websites which are in RuNet are more subject to influence of two search engines: Yandex (about 73% of all share of the market) and Google (about 21%). Filters of these projects force many seo-optimizers and web masters to waste budgets and to use exclusively white ways of advance.
Check of filters of Yandex
The most widespread option is the AGS filter. This filter extends mainly to low-quality resources which use not absolutely white methods of advance. As a rule, such projects do not bear any practical benefits for visitors and are used only for receiving profit.
Yandex considers it expedient to exclude similar projects from the index that delivery was more better also than relevant. The filter easily decides on the help of number of the indexed pages. If it suddenly decreased up to 1-5, then this filter was for certain imposed on the website. The same can be told if pages of the new website are not included into the index at all.
The second most popular is the ban. In this case all pages drop out of the index. It is possible to check existence of this filter by means of the web master's panel. If the resource cannot be added in any way, then it is banned.
Also now there was a new filter which lowers positions of the website winding behavioural factors. For check it is necessary to stop doing wrapping (if it is) or to analyze actions of users. If the number of failures was sharply reduced, and each visitor browses on several pages, then you are tried to be set up, for certain, in the opinion of PS.
In addition you can use other method. Enter a keyword and look on what position there is a website. Then add to request "-any text". For example, "how to untwist the website - pelmeshka". Delivery without behavioural factors will be displayed. If in the second case of a position are much better, then the filter is imposed.
The "falling of positions" filter is imposed on resources which, according to Yandex, wind reference. For its check it is enough to copy some piece of the unique text and to insert it into a search string. If the page is not on the first three positions, then the filter, most likely, takes place to be.
The last is the filter of affiliate. It is entered when at the search engine suspects that resources belong to the same person. For check it is enough to enter a keyword from a semantic kernel of both resources. If both of them are present at delivery, means the filter is not present.
Check of filters of Google
The most popular filter from Google is a sandbox. Young projects do not come to the first positions in search engines because of indexation term. This period can last of several months before couple of days.
Everything depends on the speed of development and promotion of the project. It is possible to check existence of the filter by means of positions. If in Yandex the website on low-frequency requests is in the first place, and in Google somewhere on 30-40, then it is under the filter.
Also domestic websites often get under the Supplemental Results or "sopli" filter. In this case pages of the website will get not to normal delivery, and to additional. Respectively, it will be impossible to achieve though any results in advance.
Under this filter the websites with sample design and the nonunique text most often get. For check just enter into a search string "site:http://вашсайт.ru/&" and compare the number of the found pages to their total on the website.
The Florida filter is imposed on the reoptimized resources. For example, if on pages a large number of keys and "nausea". The main sign of this filter - sharp decrease in positions. On another, unfortunately, it is impossible to check in any way.
For the same reason more malicious filter - "minus thirty" can be imposed. It is called in honor of the fact that all positions of the website fall on 20-40 points. According to statements of the Google company, it is impossible to be selected from this filter. Besides, after a while the website can be banned in general.
