How we work with San Diego businesses.

Four steps from first call to reporting. You own your accounts, your website and your data the whole way.

  1. Free audit

    We review your website, Google Business Profile, ads and the San Diego competitors you're up against.

  2. Plan and proposal

    A written plan with channels, budget and targets for your market. You approve the scope and price before any work starts.

  3. Build and launch

    Your team sets up tracking, fixes what holds you back and launches campaigns, pages and content.

  4. Report and improve

    A live dashboard shows leads, calls, sales and spend, and your PM walks you through it on a regular call.

No San Diego office.
Here's how that works.

We don't have a storefront in San Diego, and we won't pretend to. SmartSites is a remote team, with people working across the country, including here in San Diego County.

  • Meet by video at a time that suits you.
  • A named project manager and specialist on every account.
  • Live reporting in your client dashboard, available any time.

San Diego digital marketing FAQs.

It depends on the channels you need, your ad budget and how competitive your market is. Most San Diego clients pay a monthly management fee, plus their own ad budget for Google Ads or social. Every plan starts with a free audit and a written proposal, so you see the scope and price before you sign.

Google Ads can send leads in the first weeks after launch. SEO builds more slowly: most campaigns show clear movement within three to six months, depending on your site and competition. We never guarantee rankings, because Google does not allow anyone to.

No. SmartSites is a remote team working across the US, including team members in San Diego and Lemon Grove. San Diego clients meet us by video, get a live reporting dashboard, and have a named project manager and specialist on every account.

The best digital marketing agency in San Diego for you is the one that can show proof from businesses like yours: case studies with real numbers, reviews you can verify on Clutch or Google, and the names of the people who will run your account. Check who owns your ad accounts and website, how results are reported, and whether the contract lets you leave. We answer all of these in the first call.

A digital marketing agency brings in customers online. For San Diego businesses that usually means SEO to rank in Google and Google Maps, paid ads on Google, Microsoft and Meta, a website built to convert, social media, and email and SMS to bring buyers back. SmartSites handles all of these under one roof.

Yes. Local SEO covers your Google Business Profile, categories, photos, reviews, service-area settings and location pages, plus consistent listings across directories.

Our 30 San Diego clients include home services companies, retail and ecommerce brands, law firms, professional services firms, B2B companies and hospitality businesses.

For most small and mid-sized San Diego businesses, yes. One agency fee buys a strategist, a PPC analyst, SEO and content specialists, designers and developers, plus the software they use. You keep ownership of your accounts and data, and you can see every result in your dashboard.
