@Zerillos, I meant that when we redesigned my site header he accidentally left the logo with hidden text (it was with font size 0). It was not spammy by any means, so not sure if this had an effect. It may be construed as suspicious but it would look more like an accident. It did not have any outwardly obvious keywords either, just a description. But at this point, not sure if this algo is that forgiving...
I'm not so well versed in what constitutes acceptable or not -- seems like this bot is putting me on edge ;) . I'm also questioning my site navigation now -- whether it's laid out reasonably or not.
I've decided to noindex all my category and archive pages as they were just all lists and I'll work on them to make them more meaty and customized, then release the pages when ready.
