Seattle marketing, start to finish

One marketing plan for Seattle service businesses

Lithium Marketing plans a Seattle contractor’s website, SEO, Google Ads and AI call answering as one system, so all four feed the same phone number and the same monthly report. Seattle’s growth rate of 21.1% between 2010 and 2020 made it one of the country’s fastest-growing large cities, and newer arrivals don’t know the established names yet. The business that shows up in search, in ads and in reviews has the best chance at their first call.

Running the four together matters most when traffic is expensive. Each click on “plumber seattle” costs $46.09 on average, and a visit that stalls on a slow site, or a call nobody picks up, wastes it. With one plan, the site turns the visit into a call, the AI receptionist answers it and SEO brings in calls you never pay a click for.

Seattle and King County

A city between two waters, inside Washington’s biggest county

Seattle is the county seat of King County, the most populous county in Washington, and King County has 2,344,939 residents. If your trucks also go to Renton, Kent or Federal Way, build the website pages, SEO targets and ad locations around each of those cities, so the plan covers every city you work in and not only the Seattle name.

Seattle sits on an isthmus between Puget Sound and Lake Washington, and the Eastside suburbs lie beyond the lake. If you want Eastside jobs as well as city work, those suburbs need their own pages and ad locations, because a page written around Seattle searches won’t speak to an Eastside customer.

King County’s trade mix

King County’s biggest trade groups and the mix each one needs

The two biggest bars on the King County chart belong to residential remodelers, with 1,651 businesses, and new home builders, with 874. They sell large projects, so most of their marketing money belongs in the website and SEO: galleries of finished work, a page for each project type and reviews that name the job.

Repair trades sit lower on the county chart, with 477 electrical contractors and 468 plumbing, heating and air-conditioning contractors. When the job is a repair someone needs today, Google Ads, the Map Pack and an answered phone do more of the selling than a gallery does.

The order we work in

How Lithium sets up a Seattle marketing plan

Jobs first, tracking second, then the services that bring in and answer the calls.

1

Choose the jobs to chase

We agree on the services with the best margins and the Seattle neighborhoods and nearby cities you want them from.

2

Trace every call to a source

Call tracking and GA4 go on the website, Google Business Profile and ads, so each call shows whether search, an ad or a listing produced it.

3

Put search and ads behind those jobs

SEO builds the pages and listings that gain ground over the months, and Google Ads covers the work you need booked this month.

4

Catch every call the marketing earns

The AI receptionist answers around the clock and books jobs, and automation sends follow-up texts and review requests after each visit.

A matching case study

One program behind a glass company’s numbers: website, SEO and Google Ads

Lithium has no Seattle case study to show you, so this one comes from Portland. Town & Country Glass, a commercial glass business there, got its website, SEO and Google Ads from Lithium as one program, and the card shows what that program produced. In the quote, Daniel Busby of Willard Power Vac, a duct, dryer vent and chimney cleaning business, describes working with Lithium in his own words.

FAQ

What Seattle contractors ask us first

DJ Van Zanten

Still curious?

Call (503) 766-5964 or email [email protected].

Is anyone at Lithium based in Seattle?

Yes, Lithium has team members in Seattle. The company is headquartered in Portland, there is no office for clients to come to, and every meeting happens over video. Co-founder DJ Van Zanten leads your strategy calls, while Allison McKenney answers the everyday questions and keeps each month’s work on schedule.

We already have a web designer. Can Lithium run only SEO and ads?

Yes. Each service is sold on its own, and you keep your current site. We’ll need access to add call tracking and conversion tags, and we may ask your designer for landing pages or fixes when the site is costing you calls. If a rebuild ever makes sense, the tracking numbers will show why.

What happens in the first 90 days of a Seattle plan?

Tracking goes in during the first month, so you can see where calls come from. Google Ads typically shows initial results within the first week, technical SEO fixes usually move within 30 days and local rankings typically take 60 to 90 days. A new website, if you need one, goes live inside that window.

Is Lithium a fit for a small crew?

Yes, if your customers look you up on Google before they call. Lithium works mostly with owner-run home service businesses such as plumbers, roofers, landscapers and painters, and has worked with 100+ businesses. A one-truck company can start with a single service and add more when the calls justify it.

What contract does a Seattle plan start with?

The usual service agreement starts with six months, then runs month to month with 30 days’ notice. Most Lithium services work that way. The AI receptionist has no contract at all, and whatever you decide, the website and domain stay in your name.
