Wikipedia’s Shift to HTTPS Triggers June 17 Fluctuations, Google's Algorithm or Search Bug?
June 23, 2015 |
For some time Wikipedia, Google’s highest ranking website has been planning a change
in its domain protocol from HTTP to HTTPS. The same move Google made in 2011. It’s a common topic at Webmaster
Forum Hangouts with Google’s John Mueller as well; HTTPS and secure, encrypted browsing is the future of the web. HTTPS is a ranking signal positively affecting a website SERP. However, a major shake-up in the Google Search results occurred as Wikipedia made the move.
It was such a shake-up that Rank Ranger’s risk
index picked up on a major spike in SERP fluctuations on June 16th and 17th.
Let’s look a little closer to see what caused the spike. We analyzed hundreds of keywords to find the statistical proof of what many in the industry speculated. We have found very convincing evidence that all points towards large movements in Wikipedia’s usual one through ten rankings. Studies
have found that Wikipedia ranks 1st in 56% of noun keyword searches and in 99% of first page results. Was this consistent during the June 17 fluctuations? On this one day, Google shuffled rankings and Wikipedia's heavily. In many cases Wikipedia was either missing from page one or completely dropped out of the top 20 SERPS. In a few cases, all the usual page one results were turned upside down, letting smaller sites into page one fun -- at least for a day.
For the brand Keyword Ford - June 16, 2015 -- https://en.wikipedia.com/wiki/Ford_Motor_Company appears for the first time in position 10. Taken from a screenshot of Rank Ranger's Search Query Landing Pages report.
On June 15, one day prior http://en.wikipedia.org/wiki/Ford_Motor_Company was ranked in it’s usual number two position. In the screenshot above, we see https://en.wikipedia.org/wiki/Ford_Motor_Company Brand Keyword position ten. Ranking above Wikipedia, five Ford dealerships that you would expect to see more often in a local search.
A couple days after, on June 19th Wikipedia is back in position two with it’s usual companions on page one; twitter.com/ford, facebook.com/ford and autoblog.com/ford, https://en.wikipedia.org/wiki/Ford_Motor_Company is now back in it’s number two place as an HTTPS site.
Multiply this kind of action for billions of searches a day, and that’s a lot of change in rankings as Wikipedia moves up and down the SERPS. This brings up a few concerns, what happens when a normal site, with strong page one ranking goes to HTTPS? SEO pros have gone to Twitter and forums
arguing back and forth about site ranking crashes from page one to unnoticed positions on page two, three or worse after a HTTPS change and 301 redirect. That’s a huge business loss for a large internet site or eCommerce business; Wikipedia bounced back quickly with some adjustments, but can the same be said for the rest of the internet sites concerned with rankings?
For restaurant chain, Capital Grille brand keyword, Wikipedia sees it’s HTTPS site appear a few days earlier. We see https://en.wikipedia.org/wiki/The_Capital_Grill as early as June 14th, and it only deviates between 9th and 10th position.
We found this to be true with many variations for the whole week of June 14th causing an almost 100% greater than average change in our rank index of over 10,000+ domains and keywords. The future according to Google is HTTPS. However as in all SEO work, rankings can be a difficult up and down
battle for page one real estate.
