Just a general warning to anyone using WP’s all in one SEO. Go into the settings and check Use noindex for Tag Archives:. I was seeing way too many SERP results and they were ranking higher than the pages. They also had empty title and description meta tags.
I also found an issue with a plugin named Global Translator. It would translate the pages and Title tags but wouldn’t translate the description and keyword meta tags. This resulted in duplicate meta descriptions and keywords.
Will let you all know if I see major changes in traffic.
