Hi there, While doing some research on the indexation status of a client I ran into something unexpected. I have my hypothesis on what might be happing, but would like a second opinion on this. The query 'site:example.org inurl:index.php' returns about 18.000 results. However, when I hover my mouse of these results, no index.php shows up in the URL. So, Google seems to think these (then duplicate content) URLs still exist, but a 301 has changed the actual goal URL? A similar things happens for inurl:page. In fact, all the 'index.php' and 'page' parameters were removed over a year back, so there in fact shouldn't be any of those left in the index by now. The dates next to the search results are 2005, 2008, etc. (i.e. far before 2013). These dates accurately reflect the times these forums topic were created. Long story short: are these ~30.000 'phantom URLs' in the index out of total of ~100.000 indexed pages hurting the search rankings in some way? What do you suggest to get them out? Submitting a 100% coverage sitemap (just a few days back) doesn't seem to have any effect on these phantom results (yet).

The website of a partner of mine was recently migrated to a new platform. Even though the content on the pages mostly stayed the same, both the HTML source (divs, meta data, headers, etc.) and URLs (removed index.php, removed capitalization, etc) changed heavily. Unfortunately, the URLs of ALL forum posts (150K+) were redirected using a 302 redirect, which was only recently discovered and swiftly changed to a 301 after the discovery. Several other important content pages (150+) weren't redirected at all at first, but most now have a 301 redirect as well. The 302 redirects and 404 content pages had been live for over 2 weeks at that point, and judging by the consistent day/day drop in organic traffic, I'm guessing Google didn't like the way this migration went. My best guess would be that Google is currently treating all these content pages as 'new' (after all, the source code changed 50%+, most of the meta data changed, the URL changed, and a 302 redirect was used). On top of that, the large number of 404's they've encountered (40K+) probably also fueled their belief of a now non-worthy-of-traffic website. Given that some of these pages had been online for almost a decade, I would love Google to see that these pages are actually new versions of the old page, and therefore pass on any link juice & authority. I had the idea of submitting a sitemap containing the most important URLs of the old website (as harvested from the Top Visited Pages from Google Analytics, because no old sitemap was ever generated...), thereby re-pointing Google to all these old pages, but presenting them with a nice 301 redirect this time instead, hopefully causing them to regain their rankings. To your best knowledge, would that help the problems I've outlined above? Could it hurt? Any other tips are welcome as well.

After having answered quite a lot of questions here, I figured it was about time to ask one of my own. Can anybody point me to decent (experimental) research articles or blogs that actually show variations in meta descriptions influence the Click Through Rate (CTR) of searchers? On dozens of websites on the internet it is stated that 'meta descriptions affect CTR', but (good scientific) sources for those statements are nowhere to be found. The only research I can find that comes closest to providing any evidence is a translated study by dynamical.biz, which states that searchers LOOK a lot at the meta description, but this study (atleast in the translation) mentions nothing of searchers actually CLICKING it. Any help would be greatly appreciated!
