With any local business, your local citations needs to be really consistent, if not it can work against you. Once everything is 100% correct this allone can boost your business. I would always do an audit and fix errors with any new site. Starting with a SEO Audit, Citation Audit as well as a Website Audit all in one.
I scrape websites, do research and look for all citations out there. I look at inconsistencies, which are correct and which needs fixing and which are duplicates.
Once I have all this info I can proceed with planning your strategy, looking at which links to build, get your pages on-site SEO in order and move forward with a well planned campaign.
