Some useful questions to ask an SEO include ( reff from : Google web master central )

No one can guarantee a #1 ranking on Google.
Beware of SEOs that claim to guarantee rankings, allege a “special relationship” with Google, or advertise a “priority submit” to Google. There is no priority submit for Google whatsoever.

Be careful if a company is secretive or won’t clearly explain what they intend to do. ASK :

Can you show me examples of your previous work and share some success stories?
Do you follow the Google Webmaster Guidelines?
Do you offer any online marketing services or advice to complement your organic search business?
What kind of results do you expect to see, and in what timeframe? How do you measure your success?
What’s your experience in my industry?
What’s your experience in my country/city?
What’s your experience developing international sites?
What are your most important SEO techniques?
What are some other things to look out for?

There are a few warning signs that you may be dealing with a rogue SEO. It’s far from a comprehensive list, so if you have any doubts, you should trust your instincts. By all means, feel free to walk away if the SEO:

owns shadow domains
puts links to their other clients on doorway pages
offers to sell keywords in the address bar
doesn’t distinguish between actual search results and ads that appear on search results pages
guarantees ranking, but only on obscure, long keyword phrases you would get anyway
operates with multiple aliases or falsified WHOIS info
gets traffic from “fake” search engines, spyware, or scumware
has had domains removed from Google’s index or is not itself listed in Google
