Hello, I hope someone can help me, or can recommend someone who could look into this in more detail a a consultancy service or something.
Our client https://bit.ly/2IjLD7X experienced a bad drop in visibility early 2017 which we didn't manage to recover from. We had a problem with one main category page that wasn't indexed anymore (it was #1 for a major keyword in the Netherlands). We were able to fix the problem eventually (had to do with the .be being indexed instead due to no hreflang) but never really recovered with that page, only the entire site around that time saw a major drop in visibility.
The client went to another agency (a renowned agency in the Netherlands) but after over half a year they haven't been able to recover. Organic visits are still down 45% compared to the same period last year. Another major Dutch keyword they ranked #1 for is now #9 for instance.
So basically two SEO agencies (we and the other one) have tried everything we could think of for the past year, but none of us seem to know what the problem is and the owner is quite desperate (it's a small store with only 3 employees and his monthly revenue is only half of what it once was.
I'm afraid a quick look into the site won't help anyone find the issue, so if someone has a good idea of how we can help this previous client I would love to hear so!
