We have custom CMS for our site, after three years we find problem in index page.
This is structure of URL :
Now we find when user change title of ads, google re-indexes this page. user may also change the title several times and now Google results for this ads like this:
- result 1 :
- result 2 :
- result 3 :
- result 4 :
Also canonical tag structure have title and caused different pages to be indexed.
Now we found a solution to this problem But for the ads that will be published from today.
We guess the number of these links is between 10,000 and 15,000.
What should we do for ads that have already been indexed?
