in the last 72 hours roughly, every inner page on my site has vanished from our primary phrases (4 total). the home page still ranks in position 2 or 3 for each phrase, but the trove of inner pages I had in positions 20-110 are completely gone.
no back links to the site except those from legit press releases. I've noticed some recent controversy about prweb, but considering the nature of the website and the releases themselves, I can't imagine anything being wrong with them. We are, after all, creating legit releases about actual events taking place around the world within our company.
All white hat on-page seo done in the last 3 months.
Does anyone know what may have happened around May 15th to inspire this?
I'm not sure on dates, but within the last 72 hours, all of our inner pages are gone. Home page still ranks in top 5 for all phrases.
Thoughts? suggestions? comments? Ideas? anyone?
