In the last webmaster hangout with John Mueller of Google I asked him why he seems to get so many questions about hreflang when I suspect a very small percentage of sites on the web actually implement it. I then asked if he knew how many sites do implement it.
He said he once ran a study and may tweet about it if he can dig it up. But it was less than 10% he said, probably much lower. I am waiting for that tweet but until then…
So I tweeted out a poll asking SEOs how many of them have dealt with hreflang in their SEO endeavours over the past 12 months. To my surprise, 55.5% of those who responded said they did work with hreflang.
Have you worked with hreflang in your SEO work in the past 12 months?

There are about 1,700 responses, so it is a pretty big sample size of the SEO world (maybe).
If you are interested in the conversation I had about this with John, it starts at 45:52 mark into the video:
