I have been receiving a lot of 404 errors on my site and I don't know why are they happening or how to solve them.
I'm monitoring them with SEO Ultimate and they all follow the same pattern:
Why are the crawlers trying to view those pages if they have never existed? Will these errors penalize my PR? How can I solve them? Will creating a redirection to the normal post URL work?
I have been researching for a while and couldn't find a solution...
Thanks in advance.
