Google Algorithm non-manual penalty. How do we fix this (quality?) drop?

[BobGW]

Hi,

See attached image.

We received a non-manual penalty on March 22, 2015. I don't think we ever came out of it. We have moved up due to the Penguin update, but we should (by DA PA) be up on the first page for tons of stuff and most keyword are lower than their true strength.

What kind of quality errors could be causing this? I assume it was a quality update. I am working on the errors, but don't see anything that would be so severe as to be penalized.

What errors/quality problems am I looking for? We have tons of unique content. Good backlinks. Good design. Good user experience except for some products. Again, what am I looking for?

Thanks.

Hi Bob

Tons of unique content but optimized? Tons but focused on keywords you want to rank? Good backlinks but are you sure? (Im not talking about seo metrics only). Etc etc...

Btw whats the domain name (can be in pm)?
