All files expire after some time (e.g. 30 days). After this time the file is not downloadable anymore and a 404 error is being shown to the users ("Your file is not available any more because it has expired").
Now I'm experiencing an increasing number of "404 crawl errors" in Google Webmaster Tools regarding those files.
My questions are:
- I want to reduce these numbers, since I think this is bad for the SEO of my site. Is this correct?
- If yes, how would you handle this?
I think 404 is the correct HTTP return code, on the other hand, over time my 404 GWT list will get longer and longer.
Any hints on this?
