Hashtag in url seems to remove the google plus one

[Peter2468]

My site has a catalogue page (catalog in US) with #anchors so that customers can get straight to them.

I even link from other pages to the #anchor on the catalogue page.

so I have for example:

www.example.co.uk/catalogue.htm

www.example.co.uk/catalogue.htm#blueitems

www.example.co.uk/catalogue.htm#redtems

I understand google doesn't index after the #, here is the post I found: http://moz.com/community/q/hashtag-anchor-text-within-content#reply_91192

So I shouldn't have an seo problem.

BUT, if I navigate to www.example.co.uk/catalogue.htm and plusone the page it will show the plusone and then I navigate to www.example.co.uk/catalogue.htm#blueitems the plus one is gone. The same happens in reverse, if i plusone www.example.co.uk/catalogue.htm#redtems, then that plusone doesn't show in www.example.co.uk/catalogue.htm.

I added rel=canonical and that fixed the plusone problem, now if you plus one /catalogue.htm#redtems it still shows on catalogue.htm

This seems a bit extreme and did I do the right things??

Looks like it's good. I have the same problem with Facebook, so I added the url in the FB embed code but Google does it automatically.

You're fine :).

Looks good to me, you used rel=canonical for the right purpose. Good job.
