16. Check for Duplicate Versions of Your Site in Google’s Index
It is important that you only allow Google to index one version of your site.
Likewise, your visitors should only be able to access your site from one place. Failure to do so can lead to crawling, indexing, and security issues.
For example, the following sites are all different versions of your site. But they should all point to one.
It's up to you whether you choose a non-www or www version. But it's better to go with one or the other.
All other versions should be 301 redirected to the main version.
You can quickly check this by typing each variation into your gambling data korea browser bar. If you are redirected to the main version of your site, everything should be fine.
17. Find and Fix Crawl Errors

Some of these issues include 404 errors, incorrectly canonicalized pages, etc. You should avoid these errors at all costs.
You can quickly identify crawl errors in Google Search Console .
Go to the “Pages” report under “Indexing”.
You will see two categories, " In Index " and " Not Indexed ".
