How to remove the CAPTCHA

When working with Wordstat, a CAPTCHA (which is a image and a field next to it where you enter the characters from the image) can appear if you are accessing the service too frequently, or are located outside the Commonwealth of Independent States or Turkey, or if your browser cannot save the required cookie file. Yandex does not have the technical means to manually remove the CAPTCHA.

Cookies can be disrupted by your browser settings, extensions changing the content of a page, or your firewall.

Check that your browser enables cookies, Flash cookies, and JavaScript. You can read about the settings needed in the following Help sections:

To check that the required cookie file has been downloaded to your browser:

  1. Click the link
  2. Try to find fuid01 in the section Technical informationYour browser's cookies.

If fuid01 isn't shown, then that means cookies are blocked. Your cookies might be blocked by a firewall or extension that limits the display of page content (for example, AdBlock). Try to find and disable these blockers. As long as fuid01 doesn't appear on your computer, a CAPTCHA will be shown.

If you do see fuid01, but the CAPTCHA doesn't go away, then reduce the number of visits to the service. As a result, the CAPTCHA will disappear automatically.

Blocked access

Access may have been restricted due to a violation of the License to use Yandex Search Engine or because your computer is infected with a virus that results in an overload on Yandex services.

Check whether or not you have violated any end user license terms.

Carefully read the text of the License to use Yandex Search Engine and make sure that your computer or your subnet computers do not use applications that violate the conditions listed in the license document . Pay particular attention to Clause 2.3.

Scan your computer for viruses

Be sure to check your computer for viruses. You can do this by using virus scanners such as CureIt! from Dr.Web or Kaspersky Lab. In addition to your regular anti-virus software, we recommend performing an additional scan using a third-party scanner, because all anti-virus applications use different virus databases. Free or trial versions of many virus scanners are available online .


If you access the internet via a shared Wi-Fi hotspot or a different type of connection that enables several computers to go online using a single IP address, scan all computers sharing the same IP for viruses.

If you are certain that the License conditions have not been violated and that the computers on your subnetwork are not infected, wait a bit.

Access to the service will become available automatically within 14 days. It is technically impossible to unblock access before this time.

Other questions

Wordstat helps to gather information about Yandex users' search terms.

The number next to each query is the predicted number of impressions per month that you can expect if you use this search term as a keyword. The system forecast is based on data from the 30 day period before statistics are updated.


The system reads data only for the Yandex search results page, ignoring requests made by users on websites in the Yandex Advertising Network.

How can I view data for past periods?

To understand the dynamics of user interest in your product, go to the Query History tab. Here you will find data for the last 2 years grouped by month. The system also plots a chart of user activity.

What additional operators are supported by Wordstat?

When using Wordstat, you can refine your queries with negative keywords and by using the following additional operators:

  • Operators ( ) (grouping) and | (or)
  • Operator + (plus)
  • Operator " " (quotation marks)
  • Operator ! (exclamation mark)
  • Operator [ ] (square brackets)

Read more about additional operators.


Additional operators will only be functional in the tabs By keyword and By region. This capability is not supported under the Query History report.
