Those two are the best. There is also semrush.

Hey Miriam, Thanks for your help. So I wanted to know can I open G+ Profile with clients domain name emails, and then with G+ to claim Google Local+ listing, because to open Google Local+ Page for client you first need to have G+ Profile account which I know thay cannot be open with any other domain name mails expect Gmail.

Thanks for the answer David, I didn't expect to get an answer from you. Everything that I know in SEO I have learned from you and the SEO Moz team, so I feel really excited that you replied. In order to claim Google Local+ I need to have a Google+ profile. I wanted to know if I could create the 250 places for each client with their emails (places@client-domain.com) and then claim all the 250 Google Local+ of the different companies, and manage them all from one Google+ account. The idea is like on facebook, where you can manage a bunch of pages with one account. P.S. If this is possible, can I afterwards authorize the client to manage their own Google Local+, in case they don't want to extend the contract with our agency?

I agree with Brad - However, you may find these links start to disappear. Lot's of these directories feature 'recent profiles' or 'new links' in the sidebar / footer etc, which causes your link to appear everywhere the template is repeated. They may reduce down to 2 or 3 links from this site over the coming weeks

Make sure the site is coded in UTF-8, then you can use ü. UTF-8 supports all special characters, incl. chinese, russian etc. and makes life easier with compatibility in general.

Would this explain why my rankings report says my competitors are not in the Top 50, but are actually ranked ahead of me?
