I do a lot of outreach for my businesses. Though because it's cold, there's no trust built at all. Of course, a call is made, but a lot of the time these business owners just google the company name. Which is good because I want them to see my site, see my reviews from Google, and our case studies. But I really want to fill up the SERPs for my company name. What's the best way to build social proof for a business?
