We are a news blog site, we'd published more than 2000 press releases from PR sites on daily basis in the last 2 years. We have not been backlinking to the original press release page on the PR sites.
We have about 20% original content on our site. Our site traffic is growing, and we plan to restructure and clean up our site to improve ranking.
We'd like to ask if we should stop publishing press releases? Or we should still publish them but link back to original press release page?
For our 2000+ existing published press releases. Would you suggest us to delete them and redirect the URL with 301 redirect? Or simply keep them as they are?
Thank you for your suggestion and insights!
