AGS is a filter of Yandex and Google search engines. It is designed to remove low-quality sites from search results. The filter almost completely excludes the resource from the index, leaving less than 30 pages.
Instructions
Step 1
First, figure out what caused the pages of the site to disappear from the index. The fact is that Yandex and Google can not only impose a filter on a resource, but also block it. This is not difficult to understand. If the number of pages has sharply decreased in the search results, for example, it was 100, and there are 20 left, then this is the work of the AGS. And if the site disappeared from the index altogether, it is a ban.
Step 2
Find the reason for the resource falling under the filter. Did you sell links? Have you updated your site regularly? Duplicate content from other resources? If you find the reason why your site fell under the Yandex and Google filter, eliminate it immediately. Or rather, remove all selling links and links that lead to low-quality sites. Make the correct internal linking. Publish only unique articles on the site. Buy links from trust resources. Remove all low-quality content.
Step 3
If your resource has come under the filter due to duplicate content, then in the robots.txt file, close the indexing of tags, archives, categories and search results, that is, all announcements, except for those on the main page. Do this: Disallow: / search / * Disallow: / 2011 / * Disallow: / author / * Disallow: / tag / * Disallow: / category / *
Step 4
Close the noindex tag in the sidebar of the category menu, calendar, archives, tag cloud, a block called "Last comments", an authorization form, all announcements of articles, except for those on the main page. That is, close all content in the sidebars, except for links to other texts of the resource. Close the category menu, leave the page menu unchanged.
Step 5
When the site is out of the filter, open the tags and categories for indexing. Do not forget to also publish new high quality and unique articles and buy from time to time a small number of links from high quality sites.
