How to Test Google Business Profile SEO Services Safely

The custom keyword ranked within eight days. The keyword slipped into the red by day 17. That is the core result of this Google Business Profile SEO services test, run over 30 days on a real tiling business profile, and it repeats a pattern the tester says he has now seen on multiple listings.

What the 30-day custom services test measured

The test tracked whether adding a custom service to a Google Business Profile affects rankings for the profile's existing primary and secondary service keywords. Three terms were monitored on one local business listing: bathroom tiling (primary), bathroom tiling repair (secondary), and mosaic tiling, added as a custom service.

The listing owner ran rank scans on three dates: the starting scan on the 9th of the month, a follow-up scan on the 17th, and a final scan at the 30-day mark. The business type and location were withheld in the published video, but the shape of the data was shown openly.

This is a single-location case study, not a controlled study. The tester, Chris Palmer, a local SEO practitioner, notes he has repeated the test several times since and seen the same pattern, but the evidence here is his own measurement, not an independent or large-sample result.

How custom services rank in Google Business Profiles

Google's own documentation explains that businesses can list services and, in many categories, add custom service names beyond the preset list. These service entries feed the profile's relevance signals for local search and Google Maps ranking. The official guidance covers this under services management in the Google Business Profile Help Center.

The hypothesis behind the test was simple: adding a custom service like mosaic tiling might make the profile eligible to rank for that exact phrase in Maps results. Rank-tracking scans, such as the grid-based scans used in the video, map where a listing appears for a keyword across a geographic grid, so any eligibility change shows up as green (ranked) or red (not ranked) cells.

Google's local ranking guidance names relevance, distance, and prominence as the core ranking factors. Service entries influence relevance, which is why adding a service can shift rankings, but relevance gains in one area can dilute how clearly the profile signals its primary category.

What the day 9 to day 17 scans showed

In the first scan window, all three keywords appeared in the results. The keyword, bathroom tiling, showed steady green coverage from the start. The secondary keyword, bathroom tiling repair, ranked on the initial scan and stayed visible.

After the custom service was added, the custom term, mosaic tiling, started to rank. The scan on the 17th showed the custom keyword gaining grid coverage, which looks like a win if you only look at that one line.

The same day 17 scan showed the first warning sign: the keyword's coverage began to weaken in parts of the grid. The tester described it as a stop signal appearing on the primary term while the custom term climbed, within just eight days of the change.

What the 30-day results revealed

By the end of the 30 days, the pattern had reversed. The custom keyword, mosaic tiling, had, in the tester's words, plummeted off the face of the earth, losing the ranking coverage it had briefly held. The gain was temporary, lasting roughly two weeks.

The keyword had not fully recovered either. The tester marked the primary term's final scan in large red letters and concluded that the custom service addition had affected both the keyword and the secondary services, weakening the profile's core relevance rather than extending it.

His conclusion, repeated in the video and in his channel's notes: adding custom service categories produces a short boost and a lasting cost. He advises against adding services the business does not actually offer, because the long-run Google Maps ranking decrease outweighs the temporary gain.

Why one keyword change affects the whole keyword set

The tester's explanation rests on how keyword sets work in search. Ranking for a term like truck accident lawyer tends to pull in related terms such as lawyer, firm, attorney, and attorneys, because relevance is evaluated across a set, not a single string. He applies the same logic in reverse on Maps: optimizing for an unrelated custom term blurs the set the profile is already winning.

This matches the way local relevance works. A profile's category and service entries together tell Google what the business is about. When entries conflict or dilute that signal, the profile can lose coverage on the terms that drive its actual business, which is exactly what the scans recorded on the primary and secondary keywords.

For practitioners, the practical reading is that service lists should mirror real offerings. A profile optimized around what it genuinely sells keeps its keyword set coherent; a profile padded with aspirational terms trades real coverage for a two-week spike.

How to run your own GBP service test without the damage

If you want to verify this on your own listing, the test design in the video is easy to copy. Keep the scope small and the timeline fixed.

1. Pick three keywords: one primary service term, one secondary term, and one custom service you are considering adding.
2. Run a baseline grid scan on a fixed start date, recording coverage for all three terms.
3. Add the custom service in your Business Profile settings and run a second scan about eight days later.
4. Run a final scan at 30 days and compare all three keywords, not just the new one.
5. Decide based on the primary term: if it weakened and the custom term faded, remove the custom service.

The most common mistake the video warns against is judging the test at day 17, when the custom term is still climbing. The decisive data sits in the 30-day scan, where the temporary nature of the boost becomes visible.

Limits of this case study

This is one business, one category, one location, and one tester's measurement. The tester says he retested several times on other profiles with the same outcome, but no independent study or large-scale dataset confirms the pattern, so treat the finding as strong practitioner evidence rather than settled fact.

The video also hides the business identity, which is understandable for a client listing but means results cannot be independently audited. Google does not document how custom services interact with primary category relevance, so the mechanism described above is the tester's interpretation, consistent with the data he shows but not officially confirmed.

What survives scrutiny is the actionable core: in this 30-day test, custom services gave a roughly two-week ranking lift on the new term and a measurable drop on the primary term. If your service list matches what you sell, the trade-off is one you probably do not need to take.

FAQ

• Do custom services in a Google Business Profile help rankings?

In this 30-day test, the custom service keyword ranked for about two weeks, then lost its coverage. The temporary lift was real but did not hold through the final scan.

• Can adding services hurt my keyword rankings?

Yes, in this case study the primary service keyword weakened within eight days of adding the custom service and had not fully recovered at 30 days. The tester's advice is to add only services the business genuinely offers.

• How long should I test a Google Business Profile change?

The test used scans on day 1, day 8, and day 30. Judging at the early scan is misleading because the custom term was still climbing then; the 30-day scan showed the actual trade-off.

• Who ran this Google Business Profile SEO services test?

Chris Palmer, a local SEO practitioner, ran the test on a tiling business profile and published the scan results in a video in February 2026. The business name and location were withheld, and the measurements are his own, not independently verified.

Turn your own SEO tests into written case studies

A test like this only earns links and clients when it is written down: the dates, the three keywords, the day 17 spike, and the day 30 collapse. Many SEO practitioners have exactly this kind of evidence sitting in videos, screen recordings, and client walkthroughs that never reach the audience searching for it.

If that sounds familiar, Skala blog takes a YouTube URL, transcribes the video, and turns it into a structured article that preserves your data and your conclusions. Paste the link, review the draft, and publish the case study your scan data already supports.
