Sanctions - are actions on the part of search engines directed towards sites that violate their promotion rules. How does this happen? After the site has been indexed in the search engine, it falls into the general library, which contains all the data about all the sites that are in the issue. As soon as the site enters the library, a robot becomes its observer. The system is configured in such a way that it periodically "views" new information about each site. And if she doesn’t like something - sanctions are imposed.
This is a nightmare for both the site owners themselves and SEO specialists and marketers. After all, no one knows exactly how the algorithms of the system work. In addition, they are constantly updated. Fortunately, there is a special service - the removal of search engine sanctions. Company specialists know how to work with the site so that the sanctions take pity on it and let it into the search results again.

Manual and Automatic Limits
Behind each filter is an anti-spam specialist. It can manually impose sanctions if you violated the promotion rules. You will know about this as the employee will send you a letter and explain why you are under the filter. The advantage of such restrictions is that they can be quickly removed by solving the issue directly with the employee.
Automatic sanctions are imposed by search engine algorithms. You will not know the exact reasons, you will only notice that the position of the site has drastically “sunk”. Removing the lock is possible, but not so fast. In any case, the business suffers losses due to restrictions.
What Can a Search Robot do?
The most common actions on the part of the search engine are:
- Absolute ban. In this case, your site disappears from the index (disappears from the shared library).
- Loss of positions in the issue. A site included in the TOP-3 can “get lost” somewhere at the end of a hundred results.
- Selective restrictions. In this case, only one or several pages of the site on which suspicious activity was noticed are blocked.

What Filters Exist and How to Remove Them?
Search engines provide a lot of different filters, which are regularly updated and become more and more strict. Depending on which of them is applied, the actions of the specialist also change. The main and most famous among SEO marketers are the following:
- Panda - is not a separate "robot", but part of the search algorithm. His focus is on content, page content, and usability. This is the oldest filter. How to understand that you were attacked by a Panda? Traffic becomes zero, site positions are falling. The site can fall under this filter if the content is completely non-unique, spammy texts are posted. To save the site, you need a full-fledged audit and comprehensive optimization.
- Penguin. Controls the link mass along which the site is promoted. Often, a resource is subject to manual verification if this filter is triggered. The main "symptom" is that the site's ratings are falling. To remedy the situation, it is necessary to revise the links, remove low-quality ones and replace them with effective and safe ones. This is done gradually.
- Hummingbird. This filter is responsible for ensuring that the pages of the site respond to queries. If the information in the search results does not correspond to what is actually on the site, then it may fall under the filter.
So, even using these filters, we can see what phenomena cause the resource to fall under sanctions. This includes spam in texts, content copied from other sites, and low-quality links used for promotion. There are other factors that increase the risks: the lack of a mobile version, black hat SEO methods.
Prevention of falling under sanctions will be promotion in professional companies.
How Can Sanctions be Lifted?

Only a step-by-step approach will help to pull the site out from under the filters. The most effective actions are:
- A complete analysis of the entire link mass of the site.
- Search for links that are not suitable for promotion: broken, outsiders, with indirect anchors.
- Content analysis: its quality and uniqueness, checking for spamming.
- An important point - it is necessary to exclude the presence of hidden texts on the site.
- Checking the integrity and consistency of the site structure.
- Detection of duplicate pages.
- Based on the data received - determining the reasons why the resource fell under the filter.
- Gradual restoration of traffic to the site.
After that, it is necessary to immediately remove the sanctions. To do this, the technician:
- Removes low-quality links;
- Replaces them with new links;
- Eliminates a high percentage of spam in texts;
- Removes duplicate pages;
- Gives recommendations on filling with new content (other specialists are involved at this stage);
- Sends a request to technical support so that the positions of the site are revised.
After that, you can engage in promotion again, but having already secured yourself. The experience of being sanctioned teaches a lot to both CEOs and business owners themselves. Many realize only after the ban that it is impossible to save on high-quality promotion.
