This would affect your Google Analytics data if you regularly use the Page Title dimension when reporting. I would recommend making the necessary changes and reporting using the Page dimension (URL). This way, when you optimize your page title, the URL will remain the same and not be split in your report.

Referral spam is getting out of control lately for all my clients' sites. I really hope Google can do something about it soon.

By giving me that link you indirectly answered my question so thanks!

A Sitemap file located at http://example.com/catalog/sitemap.xml can include any URLs starting with http://example.com/catalog/ but can not include URLs starting with http://example.com/images/.

Having all my sitemaps in a /sitemaps/ folder meant that each of those sitemaps could only include URLs beginning with example.com/sitemaps/. I moved all my sub-sitemaps to my root (similar to how wordpress does it) so that they cover the scope of my entire site.

I have a sitemap-index.xml file in the root. I then have several sitemaps linked to from the index in example.com/sitemaps/sitemap1.xml, example.com/sitemaps/sitemap2.xml, etc. I have seen on other sites that for example a sitemap containing blogs where the blogs are located at example.com/blog/blog1/ would be located at example.com/blog/sitemap.xml. Is it necessary to have the sitemap located in the same folder like this? I would like to have all sitemaps in a single sitemap folder for convenience but not if it will confuse search engines. My index count for URLs in some sitemaps has dropped dramatically in Google Webmaster Tools over the past month or so and I'm not sure if this is having an effect. If it matters, I have all sitemap files, including the index, listed in the robots.txt file.

Looking at this again, It could also be due to the fact that part of the keyword searched for (PSZ-HA1T) appears at the very end of your title tag and would likely not show up in SERPs (due to your title tag being too long).

Try reworking it so this keyword would appear in the first ~512 pixels.

The most likely explanation of why your page's title was changed is because it doesn't mention your company/website at all. Google may have thought that the title was misleading and may cause searchers to think they are visiting a website that is official endorsed by Sony. Try adding some branding to the end of your title tags like Google did for you in the example. Something like "- Tape and Media" or " - TapeandMedia.com" to avoid that kind of confusion.
