Case study: a Denver-area garage and ADU builder

A Denver-area garage and ADU builder we work with recorded 2,242 organic search sessions in the 12 months to October 14, 2026, up 127% from 986 a year earlier (GA4). Its organic key events rose from 80 to 112 (GA4), a smaller increase. On October 15, 2026, ChatGPT listed the builder second on two prompts.

What the business is

The company builds detached garages and accessory dwelling units (ADUs) across the Denver metro area, including Lakewood. It sits in the home services group of businesses on our home services marketing page, and this page describes it by trade and place without naming it.

Our office sits in Boynton Beach, Florida, and clients meet us on Google Meet or Zoom. We have no published figures for the builder’s revenue, completed jobs or customers, and no published start date.

The situation

The builder’s site drew 986 organic search sessions in the 12 months to October 14, 2025 (GA4), and organic search produced 80 key events, counted as the site’s GA4 is configured. GA4’s AI Assistant channel recorded no sessions in that range.

This page has no figures for the builder’s other channels.

What was done

The service is SEO with AI visibility work alongside it, and the work is ongoing. Our SEO services and AEO services pages describe both. You approve every page before it goes live.

Because no start date is published, this page cannot tell you how much of either 12-month range fell inside the work. The figures below do not show that any task of ours produced them.

Organic sessions were higher than in the same month a year earlier in every full month from November 2025 to September 2026. The peak was August 2026, with 294 sessions against 89 in August 2025, about 3.3 times as many. October 2025 and October 2026 are partial months in these ranges and are not reported.

Organic key events rose 40% against 127% for organic sessions over the same two ranges (GA4). Key events are counted as the site’s GA4 is configured.

GA4’s AI Assistant channel recorded 28 sessions over the 12 months to October 14, 2026, with 7 key events from that traffic.

A separate GA4 view by source and medium counted 32 AI-engine sessions in the six months to October 14, 2026, again with 7 key events. Seven key events from that many sessions is a high rate for a small amount of traffic. The two views use different groupings and ranges, so their counts are never added together.

On October 15, 2026, ChatGPT answered two prompts, one about detached garage builders in the Denver metro area and one about ADU builders in Lakewood. The builder was listed second in both answers. This page reports ChatGPT alone, and it names the prompts by topic without their exact wording.

What an owner in the same industry can take from it

  • Check which AI grouping your report uses. A channel report and a source and medium report can return different counts for different ranges, as the two AI counts on this page show. Pick one, fix the range, and keep both choices the same each month. Our guide to tracking ChatGPT traffic in GA4 shows where each one sits.
  • Test a metro prompt and a suburb prompt separately. This builder was checked on a metro-level search and a Lakewood search, and an answer to one tells you nothing certain about the other. Save the date, the engine and the wording each time.
  • Read key events beside sessions. Here visits grew faster than events, so ask what your site counts as a key event and whether form fills and calls are included before you judge a rise.

Price for this kind of work

SEO at Good At Marketing is $1,000 to $1,600 a month, up to about $3,500 in competitive markets, and our pricing page places home services at the upper end of that range. AEO and AI visibility is $950 to $2,000 a month and is sold alongside SEO. Prices reviewed October 2026. That is the current price list and not a statement of what the builder pays. The SEO cost guide and the AEO cost guide explain what moves a quote.

FAQ

Why does this page show two AI session counts?

Each count comes from a different GA4 report. One groups traffic by channel and the other lists each source and medium on its own, over a different date range. This page shows both and never adds them. In your own reporting, pick one, write down its date range, and use only that one each month.

What does 7 key events from 32 AI-engine sessions tell me?

It compares events with sessions. It does not give the share of visitors who acted, because one session can record more than one event. With only 32 sessions, a single event more or fewer shifts the ratio a lot, so read it as one site’s observation and not a forecast for yours.

Does second place on ChatGPT count as a result?

On October 15, 2026, ChatGPT listed the builder second on a Denver metro prompt and on a Lakewood prompt. That is one engine on one day. Answers can change with the day, the wording and the signed-in state, so the page promises nothing about where any business will be listed.

How does a Denver builder work with a Boynton Beach agency?

We meet clients by Google Meet or Zoom. The free AI-visibility audit comes first, then a 15-minute call. The SEO and AEO price ranges are published on the pricing page, so you can see the monthly cost before the call and compare it with what you pay today.
