Welcome to the Q&A Forum

Any update on this so far Daria?

Thank you very much. As I said I use this guide for several years and for me it apears to work well but for SEO it's always important to stay on the top of things.

If the 3rd party will allow for it, then this is definitely recommended. Most local search platforms do this (Yelp, YP, etc). But if the 3rd party will not allow you to markup your NAP on your own, just having the data consistent will be beneficial to you.

Hi Daria, That is tough if these wrong citations are stemming from personal websites rather than business directories. I can see how it will be harder to get them changed. You are doing what would be advised - writing to the owners to request that they either edit or remove the citation. With directories, it's more formalized, so easier. But, the process is the same - finding everything you can and slogging through trying to get them changed. If a couple of weeks go by and you haven't heard from the bloggers, I would write again. You could also try commenting on the blog posts that reference the business. Finally, you can also start a thread in the Google and Your Business Forum to discuss your inability to remove old citations: http://groups.google.com/a/googleproductforums.com/forum/#!forum/business I'm glad a refresher on the guidelines helped you to identify and issue you were having. Good luck, Daria!
