What are citations and why are they important to local SEO?
A citation is an online reference to your business’s name, address and phone number (NAP). Google uses citations, and also links to your website, when evaluating the online authority of your business. Unlike links though, citations don’t need to be linked to your business’s website in order for you to be credited for them.
To optimize for local SEO, most businesses should track local citations, fix incorrect citations, and create citations from high authority sites and sites that pertain to a particular business category. A law firm, for example, might require citations from AVVO whereas a restaurant needs to make sure its NAP information is accurate on YELP
