The basic mechanism behind every rank-checking tool looks as follows: when you check your rankings or any other search engine related factors, the software sends queries to Search Engines. When Google or any other Search Engine receives a comparatively big number of queries coming from one IP address, it may ask you to resolve a recaptcha to confirm the requests are being sent by a human being and not a robot, or even block your IP temporarily. This is done to prevent their servers from overload with automated requests.
SEO PowerSuite offers a number of solutions to that. There are multiple Search Safety options in Rank Tracker, intended to either prevent your IP from being used or minimize the risks of your IP getting temporarily blocked (and reduce the number of captchas that pop up throughout the checks).
In the free version, Rank Tracker will use your IP by default to perform all the checks. To protect your IP from getting blocked for excessive queries, make sure you enable both 'Show Captcha…' options under Preferences > Search Safety Settings > Captcha Settings. To prove the queries are not automated, you shouldn't skip any of the captchas during the search.
To minimize the number of captchas that pop up, you can reasonably limit the number of queries sent, and make them look more human-like.
In Preferences > Search Safety Settings > Human Emulation you can set the program to visit the search engine's homepage, and enable random pauses between making queries, which emulates natural human behavior.
In Preferences > Search Safety Settings > User Agents you can set a Specific User-Agent if needed. By default, Rank Tracker is rotating user agents and performs search queries using random ones.
If you have a licensed version of Rank Tracker (Pro or Enterprise) with an active Search Algo Updates subscription, you can use the Safe Query Mode to run the checks.
The concept behind the mode is that the requests are being processed on our end, protecting your IP from being used, detected, and blocked. With the mode, you don't see any captchas while the program runs the tasks covered by the mode.
You may check the detailed explanation of mode and the list of tasks it covers here.
In case safe querying mode is enabled, some other settings may still be in conflict with it, and may not allow the program to switch to the mode. Check this guide to make sure all the settings are in line with the mode.
In both free and paid versions of RankTracker, you have an option to use your own private proxies instead of your IP or our safe-querying mode.
With the Proxy Rotation feature on, the program will connect to search engines through the proxies instead of your IP and distribute the requests between them to keep your checks uninterrupted.
This also allows you to speed up the workflow, as you can set a higher number of simultaneous tasks and update multiple projects quickly.
To start using proxies, go to Preferences > Search Safety Settings > Proxy Rotation and enable it. You can Add the proxies by one, or Import them in bulk (the wizard will show the required format of the proxies list).
Once the proxies are imported, you can select any of them to be used, and Check their status anytime.
If you'd like Rank Tracker to use a proxy instead of your IP when it performs the tasks requiring direct connection (connecting to your AdWords, Google Analytics accounts, and some others), set up a proxy under Preferences > Proxy Settings. We recommend using the proxy with the best response time here.
If you'd rather not resolve captchas manually, or if you need to leave the software running unattended, consider getting an anti-captcha key. You can get our SEO PowerSuite Anti-Captcha key here, and paste it under Preferences > Search Safety Settings > Captcha Settings - simply enable the Automatic Captcha Recognition and enter the key code.
The captchas will be resolved automatically in the background, keeping your proxies safe. With the reasonable number of tasks and moderate human emulation settings, even a key for 1K captchas may really last a while.
