I am sure you have seen it at least a 100 times, a person complaining their site doesn't rank well in Google. You look at the site and say, well, there are thousands of other sites competing for the same terms and your web site, well, has nothing unique and value-add compared to the other 1,000 web sites.
Google's John Mueller responded in the same tone, to an adult (NSFW) site who complained about some issues in the Google Webmaster Help forums.
John said your site "doesn't impress Googlebot much" because it is "essentially the same as so many other sites that just reuse video feeds."
Here is what John wrote:
The bigger problem is that your site is essentially the same as so many other sites that just reuse video feeds. That doesn't impress Googlebot much, so while i understand it's not trivial, I think in the long run it would be really helpful to just make sure that you offer something that users explicitly want to see from your site, something that they'll recommend over all of the other, similar sites, something unique, compelling and of high quality. That isn't something which can be fixed with a meta-tag, so instead of spending too much time on the technicalities of language-detection, I'd take a step back and think about what you could do to make something much more significant.
I run into this so often and why you can squeeze things out of an ordinary site, why? Why not go big and better? But going outside of the box for most of these business owners is just way too hard.
