This seems like a stretch, but despite doing everything right (I think), search traffic for a recently launched mobile site has tanked and I can't figure out why... My company has a main Google Analytics accounts, a Tag Manager account, Custom Search, Webmaster Tools, etc. Basically, all Google products are linked. However, when I recently launched our organization's new mobile site - I included a Tag Master script that I created on my own, separate from the company's account. Can that affect search? Basically our mobile site has dropped from about 5,000+ daily impressions in search engine results to about 200 (and the drop happened within 2-days after launching the new mobile site). The sitemap.xml file looks right, the META information is ok, the robots.txt file isn't throwing out any errors, there are no major crawl errors, etc...
