How to handle spam SEO companies soliciting your clients?

[CFSSEO]

My clients keep getting spam email or messages in the contact form, about how they could be ranking better, they're not hitting keywords they should be, etc.  Typical scare tactics trying to solicit new clients.

How do you deal with this?

ha ha... thanks for the story.  Great!

When they call me, I just tell them don't call back.

I don't have the answer you are looking for but I wanted to share what my main "client" does.  My husband is a real estate agent, and he is the reason why I got into SEO.  I learned how to optimize his site and have done very well at it.

He gets calls several times a week from people who want to rank his site (despite the fact that he is ranking well for most terms.)  This is what he tells them:  I have a really good SEO working for me already.  She's super expensive but she's good.  She's so good, in fact, that I married her.

The SEO usually doesn't know what to say after that.  

btw...what I usually tell people in regards to SEOs who call or email for business is that all of the really good SEOs don't have the time or the need to make unsolicited phone calls for business.  The good ones have people beating down their door.  If someone is calling and begging for your business then they probably are an amateur and don't know what they are doing.
