San Diego digital marketing FAQs.

It depends on the channels you need, your ad budget and how competitive your market is. SEO starts at $2,600 a month, and PPC management starts at $750 a month or 15% of your ad spend, whichever is greater. Most San Diego clients pay a monthly management fee, plus their own ad budget for Google Ads or social. Every proposal includes a free review of where you stand today, so you see the scope and price before any work starts.

Google Ads campaigns usually go live 1.5 to 2.5 weeks after we have access to your accounts, then need a learning period of about 2 to 4 weeks, so the first weeks are for gathering data. SEO builds more slowly: expect about 3 to 5 months for meaningful traffic and leads, though some clients see results in as little as 60 days, depending on your site and competition. Rankings usually move first, then traffic, then leads. We never guarantee rankings, because as Google itself says, no one can guarantee a #1 ranking.

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, see live reporting in the Client Hub, 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 how often you will meet. 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.
