Over at the Google Webmaster Central Blog, Google has put up a valuable post, that every Webmaster should definitely go through. In the post, Google has explained in length as to how Webmasters can determine the factors, that would lead them to file a reconsideration request to Google in case their website gets banned. It also shows (via a video) the method of filing the reconsideration request through Google Webmaster Tools.
It can happen to anyone at anytime, that your website might disappear from the Google Search Results. One of the possible reasons for this to happen is that, Google has stopped indexing your website altogether. In such a case, you can always file a reconsideration request to Google via the Webmaster Tools. Watch the video below, to understand the correct procedure, that you should follow while filing a reconsideration request.
However, you first need to be absolutely certain that Google has deliberately stopped crawling your website. Follow the below mentioned checklist to make sure that there aren't anomalies that are hindering the indexing of your website:
- Check for access issues: One of the reasons that your website might stop getting indexed is if your website is facing any access issues. It means that, the Google crawlers aren't able to crawl your website due to unavailability of the site. You can check for access issues by logging in to your Webmaster Tools account. There in the 'Overview' page, you'll be able to check as to the last successful crawl made by Googlebot of your home page. You can also check for any crawling errors that the Googlebot might have faced. For example, if your server was busy or unavailable when we tried to access your site, you would get a "URL unreachable" error message. A more common error can be that some pages could be blocked by a robots.txt file. You can see this in "URLs restricted by robots.txt". If there are URLs listed there which you did not expect, you can go to Tools and select "Analyze robots.txt" – there you can make sure that your robots.txt file is properly formatted and only blocking the parts of your site which you don't want Google to crawl.
- Check for messages: If you do not find any access issues, then you should head over to the Message Center of your Webmaster Tools account to check for any unread message from Google. The message center is, where Google sends important information regarding your Webmaster Tools account and the websites that you manage through that account. If Google finds something in your website that does not adhere to its Webmaster Guidelines, then Google will intimate you with a message, asking you to make certain changes in your website, to bring it in compliance with Google Webmaster Guidelines.
- Go Through the Google Webmaster Guidelines: If you find none of the above two issues with your website, then you need to go through the Google Webmaster Guidelines, to observe if your website at any point of time has violated the Google Webmaster Guidelines.
- Make Corrections: In case if you do find your website in violation of the Google Webmaster Guidelines, then you should promptly fix the issues that have caused the de-indexing of your website.
- Submit a Reconsideration Request: Now that you've made the necessary changes to your website, it is time to submit the reconsideration request to Google. Log in to your Webmaster Tools account. Under Tools, click on "Request reconsideration" and follow the steps. Make sure to explain what you think was wrong with your site and what steps you have taken to fix it. Once done, you will then receive a message from Google (in your Message Center, of course!). Google will confirm the receipt of the reconsideration request, after which it will review your website and would check whether your changes are consistent with Google Webmaster Guidelines.
It is not too difficult to submit a reconsideration request to Google, but it is always better to double check your facts before, asking Google to re-index your website, when Google never de-indexed it.
