Currently working on a local SEO project, I have run a citation audit for my client's website and found out he has more than 1000 incorrect citations on various web directories (either incorrect company name, phone, URL or address).
as cleaning up more than 1000 citations can be a tedious task, I'd like to know what would be the best way to proceed? Should I (or my client) pay any particular online service to clean up those citations?
If so, which services do you find the most effective (Whitespark, Brighlocal, Loganix, etc....)?
You advice on this is highly appreciated!
