The short version

What one plan covers in Centennial

Lithium Marketing runs the website, SEO, Google Ads and AI receptionist for Centennial service businesses so fewer calls slip away. A customer can be lost in four places: a slow site, a thin search presence, an ad budget with no tracking or a phone nobody answers. The Denver-Aurora-Centennial metro area has 3,092,037 residents, and Centennial sits inside it, so your pages can answer searches from beyond the city line.

Centennial has 108,658 residents. Of Centennial’s occupied homes, 80.6% are owner-occupied, so the plan puts the work you do for owners in front of the right searches: repairs, replacements, remodels and maintenance, each with its own page.

The Centennial market

Older homes, owners and the work that follows

42.9% of Centennial’s homes went up before 1980, so repair and replacement pages matter for plumbers, HVAC companies, roofers and electricians. The site needs a page for each job, not one general services list.

A $658,100 median value in Centennial means owners are protecting a serious asset. Your site should prove you have worked on homes like theirs, with photos from finished jobs and a service list that is easy to scan.

Trades in Arapahoe County

The county’s contractor mix, by the numbers

Arapahoe County has 323 residential remodelers, 251 plumbing, heating and air-conditioning contractors, 231 landscaping services, 220 electrical contractors and 102 roofing contractors. With that many companies selling the same work, the plan has to make your business look different: your reviews, your finished projects and a page for the service the customer searched.

For your business, that means a page and its own photos for each kind of job you sell, so a roofer and a landscaper are not sharing one services list.

The order of work

What gets built first in Centennial

Tracking comes before spending, so every later decision has a number behind it.

1

List the services and cities

You name the trades you sell and the nearby cities your crews cover. We turn that list into the pages, ad targets and receptionist answers.

2

Track every call and form

GA4 and call tracking go on the website, the Google Business Profile and any ads, so the first report shows where Centennial jobs come from.

3

Fix or build the site

A slow site or a form that fails on a phone gets fixed first, because search and ads both send customers there.

4

Add search, ads and phones

SEO and Google Ads go after the jobs you want next, and the AI receptionist answers the calls both produce.

Proof

The fence company behind the numbers

F&W Fence Co. is the fence company on the card. Lithium rebuilt its site and handled both its SEO and Google Ads, so the result belongs to the whole project. Nathan Boos of Hillsview Building adds a separate owner’s view beside it.

FAQ

What Centennial owners ask before they sign

DJ Van Zanten

Still curious?

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

Where should a Centennial owner start when the website, search and phones all need work?

Look at where a ready customer drops out. A call that rings out points to phone answering, a page that stalls on a phone points to a rebuild, and a site that never appears points to search or ads. A co-founder reads the tracking with you and sets the sequence.

Can we start with the website and add SEO later?

One service is enough to begin. When you add another, the existing call tracking covers it, so the monthly report can compare the new work with the old on one page.

Who runs the strategy calls for a Centennial business?

DJ Van Zanten, a co-founder, takes every strategy call, and Allison McKenney handles day-to-day questions. Lithium is headquartered in Portland, Oregon, with a team in Portland, Bend and Seattle, working with every client by video.

How does the price change when we add a second service?

The bill is built service by service, and you only pay for the ones you pick. SEO depends on how many services and cities you want covered, the Google Ads fee follows ad spend and channels, and a bigger site gets a fixed proposal before work begins.

What does the service agreement look like?

The usual service agreement starts with a six-month first term. After that it runs month to month, and either side can end it with 30 days’ notice. The AI receptionist is the exception, with no contract.
