We are using Salesforce's Visualforce to run one of our websites.
We use Moz to monitor SEO issues.
Moz has identified more issues pages than we have - see the attached image. We have only a few thousand pages at best. However Google and Moz are taking keywords and adding it to the end of the domain and creating a URL that doesn't exist. Recently I made all of these URLs redirect to the home page to see if it resolved the issue - it didn't and the URLs that don't exist are still being crawled.
What do I do - this is effecting my rank. Please help?
The CMS was just trying to serve broken pages on unreal URLs. I had to add a small php script that identified if the URL was valid or not. If the your was invalid it would redirect to a 404 page
