Hi there
I wonder if someone can help me out and provide the best solution for a problem with form generated pages.
I have blocked the search results pages from being indexed by using the 'no index' tag, and I wondered if I should take this approach for the following pages. I have seen a huge increase in 404 errors since the new site structure and forms being filled in. This is because every time a form is filled in, this generates a new page, which only Google Search Console is reporting as a 404.
Whilst some 404's can be explained and resolved, I wondered what is best to prevent Google from crawling these pages, like this: mydomain.com/webapp/wcs/stores/servlet/TopCategoriesDisplay?langId=-1&storeId=90&catalogId=1008&homePage=Y
Implement 301 redirect using rules, which will mean that all these pages will redirect to the homepage. Whilst in theory this will protect any linked to pages, it does not resolve this issue of why GSC is recording as 404's in the first place. Also could come across to Google as 100,000+ redirected links, which might look spammy.
Place No index tag on these pages too, so they will not get picked up, in the same way the search result pages are not being indexed.
Block in robots - this will prevent any 'result' pages being crawled, which will improve the crawl time currently being taken up. However, I'm not entirely sure if the block will be possible? I would need to block anything after the domain/webapp/wcs/stores/servlet/TopCategoriesDisplay?. Hopefully this is possible?
The no index tag will take time to set up, as needs to be scheduled in with development team, but the robots.txt will be an quicker fix as this can be done in GSC.
I really appreciate any feedback on this one.
Many thanks
