If you've already verified ownership of your site, you can skip the first action below and go right to checking your site information in Search Console.

You'll need

• The ability to verify ownership of your site using a technique such as adding a file in the root directory, authoring of meta tags, owning a Google Analytics administrative account for the site, etc.

What you'll do

In this section, you'll perform the following actions:

1. Verify ownership of your site in Search Console.
2. Check that the hacker didn't already verify ownership in Search Console and make unwanted settings changes.
3. Determine the nature of the attack.

Verify ownership of your site in Search Console {: #verify }

1. Open a browser and navigate to Webmaster Central.
2. Click Search Console.
3. Sign in to Search Console using a Google account. If you don't have a Google account, click Create an account. A new Google account doesn't mean you'll lose your existing email account with another company. (More information about accounts.)
4. Click Add a site. Type your site's URL in the box, then click Continue.
5. Decide the most convenient verification method for you. The Recommended method tab on the verification page shows the method Google thinks will work best. Additional methods are listed on the Alternate methods tab. (More information about verification.)
6. Bring your site back online if you selected a verification method that requires access to your site, such as HTML meta tag or HTML file.
7. Click Verify to verify ownership using your selected method. If verification is successful, you'll see a congratulatory screen mentioning that you're a verified owner. You can take your site back offline, but be aware that it will need to be back online in future steps.

Check that the hacker didn't already verify ownership {: #check }

Once verified, check that the hacker didn't already verify ownership in Search Console and make unwanted settings changes.

1. Navigate to the main Search Console homepage by clicking the Search Console logo.
2. Find your site, then click Manage site.
3. Click Add or remove users.
4. Be sure that all users and owners listed are authorized.
5. Document the email address of any unauthorized user (in case it's helpful in the future), then delete the user from your site. For unauthorized owners, you'll need to both delete the owner and any possible verification tokens, such as a verification metatag on your homepage or a HTML file on your server. (More information.)
6. Investigate for unwanted settings changes in Search Console. Click the settings Settings icon, then click Site Settings to check for possible undesirable changes by the hacker such as a lower Crawl rate (perhaps with the goal to avoid search engine spiders). Also, check that nothing unusual is listed in the section Google Index > Remove URLs or settings > Change of Address.
