San Diego’s Covario, which provides search marketing services for Fortune 500 companies, says today it has acquired Top Local Search, a San Diego-based firm that provides “hyperlocal” search engine optimization (SEO) products and services.

Covario plans to combine Top Local Search with its new Rio SEO business unit, which was created in April to serve a broader market that consists mostly of small and medium businesses, the in-house marketing teams at bigger companies, and other search marketing agencies. “The addition of Top Local Search broadens or extends Rio SEO’s line of automated search

In addition to offering a line of automated SEO software products, Rio SEO will provide SEO as a Web-based service, along with content marketing and social media software.
