Your Google Business Profile gives you 750 characters to describe your business. Most local service businesses use about a hundred of them, write something generic, and move on. That's a missed opportunity that costs more than most people realize.
The description isn't the most powerful field on your profile, but it's the most underused one, and getting it right is straightforward once you know the actual rules Google applies and the specific things it's looking for.
The 244-character rule nobody talks about
Google shows the first 244 characters of your description in search results before truncating the rest with a "More" link that most searchers won't click. This means the first sentence and a half of your description is doing almost all of the actual work. Whatever matters most about your business needs to be in those first 244 characters, not buried at the end.
The mistake most businesses make is writing the description in the order they think of things, not in the order a potential customer needs to see them. They open with their founding year or their family history and bury their service area and core offering three sentences in. Flip that. Put the most important information first.
What Google's algorithm actually looks for
The description field is a confirmed ranking signal, but a limited one compared to your primary category or review content. What it does well is fill in specificity gaps, particularly for service area and service type, that help Google match your profile to more specific searches.
A plumber in a Chicago suburb who writes "licensed plumbing services" in their description will rank differently than one who writes "emergency plumbing, drain cleaning, and water heater installation serving Oak Park, River Forest, and Berwyn." The second version gives Google explicit location and service signals that the first doesn't. Those signals directly affect which searches trigger your profile to appear.
Keywords belong in the description, but naturally, not stuffed. Google's 2026 category guidelines explicitly flag profiles that misuse popular terms as a ranking penalty risk. Write for the person reading it first, and the algorithm second.
What the description can't do
There are specific things Google's guidelines prohibit in the description field, and knowing them prevents a profile suspension. No links or URLs. No promotional offers or pricing. No phone numbers. No content that belongs in other fields, like hours or address. Essentially, the description should describe what your business does and what makes it worth choosing, not duplicate fields that exist elsewhere or function as an ad.
A formula that works
The structure that consistently performs well follows a simple pattern: who you are, what you do, where you serve, and why you over the alternatives. Keep it to facts, not superlatives. "Serving the west suburbs for fifteen years" is a verifiable fact that builds credibility. "Best plumber in Chicago" is a claim Google treats skeptically and customers don't believe.
A concrete example: "Licensed plumber serving Oak Park, Berwyn, and River Forest. Specializing in emergency drain clearing, water heater installation, and pipe repair. Same-day appointments available. Family-owned, licensed and insured." That's 195 characters. Factual, specific, locally grounded, and leaves room to add one differentiator before the 244-character cutoff.
Use the remaining characters up to 750 for secondary services, service area expansions, or anything else that helps a specific type of searcher know they're in the right place. Think of the first 244 as your pitch and the rest as supporting detail for the people who actually click More.
The one field most businesses ignore that does more work
The description gets attention because it's visible. But the services section, where you list individual services with their own names and descriptions, is doing more direct ranking work for specific search queries. A plumber who lists "Emergency Drain Clearing," "Water Heater Installation," and "Pipe Burst Repair" as separate services with two-sentence descriptions each will match more specific searches than a competitor with a single line that says "All Plumbing Services."
If you have thirty minutes to spend on your Google Business Profile, the description and the services list together are where that time produces the most measurable return. Start with the description, then work through the services, and both together will outperform most of what any reputation management platform automates on your behalf.
