Market profile
St. Johns County Is Building Faster Than Most Counties
St. Johns County builds a lot for its size: 147.9 new housing units were authorized per 10,000 residents in 2025, more than in 98% of counties. New homes mean new households that need contractors, insurers, agents and healthcare providers, and the first search for each is a chance to be found.
St. Johns County has 320,110 residents, which ranks 227th of 3,143 U.S. counties, and the headcount has shifted +17.1% since the 2020 Census.
No single place dominates St. Johns County: the largest, St. Augustine, holds about 5% of residents. Larger places include St. Augustine (15,596), St. Augustine Beach (6,779) and Marineland (1). Each is a market of its own, and we set campaigns up around the ones you serve.
93% of residents (297,734 people) live outside any incorporated place. Radius and ZIP targeting reach them where city-only targeting would not.
Demand signal
New Homes in St. Johns County: Below the 2021 Peak, Still Slowing This Year
Housing units authorized by building permits. Data: U.S. Census Bureau Building Permits Survey (county annual files, and the year-to-date bars compare the same months each year). Permits count homes approved to be built, not homes completed.
St. Johns County authorized 8,390 housing units in 2021 and 4,735 in 2025, about 44% fewer; 2025 still works out to 147.9 units per 10,000 residents, more than in 98% of counties. From January through August, 2,362 units have been permitted, compared with 3,669 a year earlier (−35.6%).
In St. Johns County, the construction-linked categories already busiest are real estate agents and brokers (6.0x typical) and landscaping services (1.7x typical). When new households are your market, treat permits as an early signal: when they turn, search demand usually follows, and your budget and ad schedule should too.

Crowding is employer locations per 10,000 residents relative to the median U.S. county of 20,000+ residents (1.0x is typical; the dark tick marks it). Counts are establishments from County Business Patterns (2017, 2022), which is not the same as active advertisers. Method
In St. Johns County, the real estate agents and brokers category is the most crowded, with 475 locations at 6.0 times the typical density; the count is up 79.9% since 2017. Physicians offices (270 locations, 2.1x) and landscaping services (180 locations, 1.7x) also sit above a normal county. At the other end, the electrical contractors category (61 locations) is below typical density at 0.8x, which can mean more room to win a strong position.
Real estate agents and brokers is also the fastest-growing category, up 79.9% since 2017, so the crowding is still building.
These are business counts, not ad costs. What a click costs is decided in an auction that depends on far more than how many competitors exist, so we build around your keywords, offer and landing page instead of the headcount.

Questions we hear
St. Johns County Google Ads Management: Your Questions Answered
How much does Google Ads management cost in St. Johns County?
Our management fee is flat: $895 a month for one platform, $1,595 for two and $2,295 for three, with no long-term contract. Ad spend is separate, paid straight to Google, Bing or Meta.
How much should I spend on ads in St. Johns County?
Work from your own numbers instead of a rule of thumb: the calculator above takes your profit per new customer and close rate and returns the most you can pay per lead. In St. Johns County, real estate agents and brokers (6.0x) and physicians offices (2.1x) are denser than a typical county, so if you are in one of those categories plan for a busier auction. Before launch we size the budget with you, then scale as results arrive.
Is St. Johns County a competitive market for Google Ads?
About average. St. Johns County scores 64.3 on our Ad Competition Index, ranking 398th of 1,822 counties with 20,000+ residents and 170th of the 400 markets we cover. Real estate agents and brokers leads on density, at 6.0 times the typical county. That rewards consistency: steady campaigns can claim ground that would be contested in a bigger market.
What kinds of local businesses advertise most in St. Johns County?
Across the twelve ad-heavy categories we track, the largest by employer locations in St. Johns County are real estate agents and brokers (475), physicians offices (270) and landscaping services (180). Measured against a typical county, the most crowded are real estate agents and brokers (6.0x) and physicians offices (2.1x). Size and crowding in a category do not decide whether ads work for you; it shows how many other businesses may be bidding on the same searches.
How soon will I get calls from Google Ads in St. Johns County?
Timing varies. Some accounts get calls the first day; others need two to four weeks of tuning, more so in busy categories like real estate agents and brokers. Early on we review which searches triggered your ads and exclude the ones that do not fit your business.
Is St. Johns County growing, and does that matter for Google Ads?
St. Johns County has 320,110 residents, +17.1% since the 2020 Census, and 4,735 housing units were permitted in 2025 (147.9 per 10,000 residents). With growth like that, new people keep arriving who have not chosen a provider. In both cases, ads reach whoever is searching right now, and that is why these trends inform the budgets we set.
Can you target only the parts of St. Johns County I serve?
Yes. We can target by city (St. Augustine, St. Augustine Beach, Marineland), by ZIP code or by a radius around your location. About 93% of residents live outside any incorporated place, and radius targeting is frequently how we reach them.
Can you manage Meta ads (Facebook and Instagram) along with Google?
Yes. Beyond Google Ads, we manage Bing ads and Meta ads, which run on Facebook and Instagram. Google usually comes first because searchers are ready to act; Bing adds a second search audience, and Facebook and Instagram reach people before they search. The fee depends on how many platforms you run: $895, $1,595 or $2,295 a month.
Am I locked into a contract, and how do I see results?
There is no contract; you can cancel anytime. A dedicated account manager handles your campaign and sends monthly reports on the calls, forms and sales.
