I've just upsold one of my newer clients (DIU Lawyer) from $997/month to $2,500/month.
Here is the situation.
He signed up with me 2 weeks before Google made the recent changes in local search, regarding Google Places. As you know, in most local areas and especially in competitive niches, the Google Places listings are now merged with the Website rankings.
All of my clients, except this one, now have even better rankings in Google thanks to the recent changes, and that's because I had the SEO in place, they all were ranking very well for their keywords organically.
I love the recent changes because we now have the possibility to charge more and clients basically have to get their SEO right, if not, they won't stand a chance against competitors that have their Google Places listing AND their SEO optimized.
Anyway, this client had no listing in the 7pack and 48hours after I finished optimizing his listing he was in the 7pack, second position - and I got him to sign up for the yellow tag. He was quite impressed and very happy to say the least.
Unfortunately, he had no SEO in place whatsover. His webiste had like 2 backlinks, it wasn't optimized for any keywords and nowhere to be found, so I got started with his SEO optimization.
One or two weeks later, Google implemented the new changes and while all my other clients improved their rankings, he dropped from the second position to the last position immediately for the main keyword, and he disappeared from the first page for secondary keywords.
I explained the changes to him, made clear to him how important SEO is now and also explained to him that his listing might disappear very soon without some serious SEO. He began to ask me how we can ensure that his listing will come back to the top, how much that would cost, and so forth.
I told him the prices for a massive SEO campaign and he agreed to do it. He knew that I know what I'm talking about because I got him amazing results in a very short amount of time.
He's so motivated now that he wants me to do the same for 2 other sites that he has.
That's how I upsold my client from 1k to 2,5k/month.
I just wanted to share my experience - you might have some clients that lost rankings because of the changes and now is a great time to sell additional SEO packages to old or new clients.
Let me know if there's anything I can help you with.
All the best,
