Over the past 15 years we have used many different SEO tools and have changed over the years. At Visual Realm we personally use the following:

Ahrefs
SEMrush
MOZ
Google Analytics
Google Tag Manager
Google Search Console
Google My Business
ZeroBounce
Yext
Hunter
GetProspect

These tools give us the strategy and ability to analyze sites, build local citations, scrape emails and make sure those emails dont bounce back. These programs are expensive but allow us to get the best SEO results for any business.
