I disagree that because it’s not showing for “casino guide” it is in the sandbox. Casino Guide is a highly targeted phrase. It’s such a common phrase, thousands of sites are targetting it unknowingly simply because it’s so easy to say “casino guide” in your text when writing about only casinos! Getting to the first page for that one takes a bit more than just getting out of the sandbox.
And that domain isn’t even targeting that phrase. Unless I’m missing something.
What I have to say is that the site may be getting serps for decent phrases after three weeks, but it may yet enter the dreaded sandbox. Often new sites slip past the radar, only to be sent to the void once detected. Of course, I don’t know what methods you used to avoid the sandbox, but I sure am interested!
p.s. While the first two phrases are ok, the phrases with “gallery” in them are worth, what, 1 visitor a year?
