30 Interesting SEO Experiments: Part 3 of 6

11. Link Spying Using Duplicate Content

While Google Webmaster Tools may only let webmasters see their own site stats, a little-known workaround will let you see link information for other peoples’ sites. By duplicating a page from a remote site onto your own site, Google Tools will deliver that site’s link information to you once your duplicate page gets indexed.

12. Google Title-Tag Replacements

Whenever Google comes across a page title stuffed full of keywords, Google reads this as a “non-informative title.” Testing this scenario involved creating a keyword-stuffed page title. Google replaced the original title with its own, though anyone searching can still pull up the page by its original title name.

13. Social Media Sharing

Online marketers set out to see if the various social medial share options (Google +1, Facebook like and reshare buttons) effect page rank overall. Using a before and after data analysis on newly created pages, page rankings did show slight improvements from clicking each of the share options.

14. Fixing a Deranking Debacle

Every now and then, a website make-over can end up getting your site deranked in search results. What does it take to regain a site’s former ranking? Marketers loaded up a well-ranked site with spammy links and then removed them and sent an appeal request to Google. The overall process to restore the site’s ranking took several weeks on Google’s end, but it is doable.

15. Tags for Multiple Domain Names on International Sites

Penalties for duplicate content can damage site rankings, even in cases where multiple domain names exist in different countries. This experiment tested to see if the hreflang and canonical tags can help ward off site penalties and improve rankings. Turns out the sites that displayed both tags did considerably better in search rankings than those that didn’t.
