Bio

I am Carlos Sandoval Jr., a San Diego marketer who came up through the trades side of the business, not the agency side. I ran lead generation as an employee at DRC Restoration in San Diego, where $360K in Google Ads became $2.6M in revenue in year one and $2.2M in year two.[1] That is where my view of marketing was formed: a lead is a booked, paid job, and anything that cannot be traced to one is a cost.

I founded Digital Dynamics to do for other contractors what I had to figure out for myself. The agency does lead generation and SEO for plumbing, restoration, roofing, electrical and remodeling companies in San Diego: local SEO, Google Business Profile work, websites built to rank, and paid ads. The agency's contact address is marketing@trydigitaldynamics.com.

I also build Checkin Signals, software so contractors own their SEO. Too many contractors rent their rankings from an agency and lose them the month they stop paying. The goal is for the business to hold its own signals.

My current focus is AI search: how ChatGPT, Google AI Mode, Google AI Overviews and Perplexity decide which plumber or restoration company to recommend. Rather than claim expertise, I am measuring it. On Oct 25, 2026 I ran a baseline of 3,060 prompt runs across three engines and was named in none of them. The method, the numbers and the follow-up results on days 7, 14 and 30 are on the study page. I publish the result either way.

The canonical spelling is Carlos Sandoval Jr. I also appear as "Carlos Sandoval" and under the handle Carlos Builds AI on video platforms. There are other people named Carlos Sandoval Jr. online, among them a Fresno-area news subject, a nurse practitioner and a filmmaker; none of them are me, and this site exists partly so that search engines can tell us apart.
