I did try this last night. I put a ad in local services with a screen shot of a local search and talking about these companies are getting business that a craigslist poster could be getting if they were listed here. Ten minutes later it was flagged down. Its frustrating knowing that the posters all need this listing and that once they get it there its there and they dont have to repost all the time and worry about getting flagged down.
Then I realized I had broken the first rule that I should be abiding by "Give them something for free so you can start building a relationship that can lead to sales.
I just went back and posted a ad offering to see if Google may have already found them and if so I would help them claim the listing for FREE and if Google hasnt found them yet that I would get them listed for FREE.
I will see how this goes. Hope to at least get a few calls so that I can get comfortable with explaining to them what this could mean for their bottom line. This will open a relationship and I can then tell them how I can get them optimized to help them move up in the listings.
What are your experiences?
