How to remove search results data from Google

[danielaaric]

One of my website was hacked a few days back. And it is now showing the wrong title & meta description in other languages in Google search results which is not on the website.
Like we perform a query like site:abc.com
So I block the website using robots.txt to de-index from the Google search engine.
Please let me know what else that I can do remove the results from SERP.

Thank you.

Use the Google search console, there, you can remove URLs (if they are no longer accessible). But, you can also ask Google to re-crawl them , but this is one by one, so if you have lot of pages, this can't really be done manually.

But I am fearing to use this tools. Is it safe ?

Blocking Google from crawling with robots.txt does not do anything to remove the site from search or to de-index pages. It only prevents them from crawling the hacked content. Crawling and indexing are two different things.

STOP, please do not take any action before you properly understand the actions. You can end up causing a bigger problem by acting too quick without understanding what you are doing.

If you were hacked, first make sure you have fully removed the hack. Some of the more challenging hacks pretend to be fixed but still show the hacked content to Googlebot & new users.

Once you are 100% sure your site is clean and hack free, I suggest you simply do nothing and wait for Googlebot to recrawl your site. If you really want to do something, build links or drive some viral traffic to entice Google to more quickly recrawl your page and update the title & description for the serps.

If you block the site with robots.txt, Google will not be able to crawl your site to discover it is now hack free. I would not use noindex tags for the same reason. It is much smarter to fix the hack and encourage Google to recrawl the clean pages as soon as possible.

If you use the Google url removal tool, you can end up removing your pages for many months. The Google url removal tool is not intended for short term problems.

The hack could cause your site to show googlebot something different from what you see yourself when you look at your pages directly. You can check this possibility by using the "fetch as googlebot" option in Google Search Console. It's completely safe to use.
Edit: P.S. You'll have to unblock googlebot in robots.txt first.

danielaaric, take a look at this currently active discussion, not because I think you should join it, or even because it sounds similar to what's happened to you... but because in discussing just one hijacked site, it goes into a great many issues that need to concern you in answering your question....

Correct the hacked content, then secure the website so it cannot be hacked again. The latter action is the part necessary for going forward to prevent yet another hack.

If your site is powered by a CMS (such as Wordpress) update/patch to the latest version, but only after installing the last HACK FREE backup of your site. Then let the search engines do their job.

There's no easy way to tell a se what's hacked and what is not ... and it will not correct overnight after the site is cleaned up. Expect 2 weeks or longer, depending on the number of urls which were affected.
