Yeah same thing happened to me but then I realized in reality my page is actually on pages 4 and 5 of google and isn't getting any traffic at all yet, outside of the WA community. But your page is full of good content though so I wouldn't be surprised if you did rank for real. My page only has 6 pots and empty "pages" so I'm not expecting miracles at this point.

Hi Sarah!
I have to tell you that VitaliyG is absolutely correct. YOU see those post on the 1st page of google because YOU searched the particular term.

Using an "incognito" browser page will give a more accurate perspective of where your post ranks.

When I saw that my own Google + links showed up that quickly I was very excited too.

Hi Sarah, these are Google Plus links. It's important to note that they will always show up on the first page when you look at terms. To see the real positions, you would have to do a search on another browsers where you're not logged into Google.

However, I can confirm that it is true that you can rank on the 1st page within hours. I think your website has more than enough content to give it that level of success!
