A search engine filter is an algorithm (set of algorithms) that studies the performance and content of websites. If violations of the established rules are detected, the rating of the resource in search results is lowered or it is completely excluded from indexing.

How to avoid getting caught by filters:

  • use white promotion technologies;
  • fill the resource with high-quality, unique content;
  • use valid code;
  • abandon “black” optimization technologies (spam purchasing of links, cloaking);
  • ensure high-quality website usability.

The main companies that use filters that can have a significant impact on website traffic are Yandex and Google. They have similar verification algorithms. By complying with the requirements of one search engine, you can avoid getting banned by another.

Yandex filters and getting out from under them

Recently, Yandex.Webmaster displays information about which company filters the site fell under. There are 3 algorithms that have the most negative impact on resource positions:

  • "Minusinsk";
  • for cheating behavioral factors;
  • AGS.

"Minusinsk"

Imposes sanctions when identifying SEO links from external sources that can significantly affect search results. A detailed and high-quality analysis of the link mass will help you get out from under the filter. It is necessary to remove most of the dubious links, leaving links from trusted donor sites. This is a creative job that requires some experience. The implementation of this task should be delegated to a competent SEO specialist.

Sanctions for defrauding the PF

Behavioral factors are statistics that provide the opportunity to evaluate the effectiveness (usefulness) of a site based on user actions (stay time, bounces, clicks on internal links, conversion rate). If the filter detects interference in the natural process on the part of the resource owner, sanctions are imposed.

Solution to the problem:

  • refusal of services from services that cheat PF;
  • comprehensive site audit and correction of technical errors;
  • removing low-quality SEO links.

CSO

A comprehensive filter that imposes sanctions for a number of factors:

  • spamming with outgoing SEO links;
  • abundance of non-unique content;
  • poor usability;
  • abundance takes .

Exiting the filter requires lengthy processing of the site - reviewing the link mass, filling it with high-quality content, changing the IDs used, removing duplicates, setting up redirects.

Google filters and getting out of them

Google has similar requirements for websites. However it has more filters:

  • Penguin". Combats low-quality link mass. We remove spam links and technical errors. If you cannot remove low-quality incoming links, they must be rejected;
  • "Panda". The algorithm that shook the world of SEO optimizers. Because of it, most of the old methods of “lazy” optimization stopped working. More than 20% of all websites in the world were affected. Panda imposes sanctions for broken links, non-unique content and an abundance of advertising irrelevant to the site’s topic. To exit, we fill the resource with high-quality texts. We remove unnecessary advertising materials, check the functionality of links;
  • "-thirty" . Punishes for the use of “black” optimization, cloaking. Lowers positions in search results by 30 points. To get out of “-30”, give up prohibited technologies. This will help correct the situation;
  • "Duplicate Content".  Sites with non-unique content are at risk. It is important to pay increased attention to the quality of posted texts;
  • "Over-optimization".  The result of overspam with keywords due to the action of this filter will be a noticeable decrease in positions in search results. To avoid sanctions, it is necessary to keep the number of keywords at the level of 6-7%.

Removing a small site from filters does not require significant time investment. Competent specialists will help you get the maximum result.
