The short version
- An agency that fakes its own Google listing will fake yours too. The listing is the first thing to check.
- Look at the name, the address, the phone area code, the review pattern, the Texas business filing and the website. Each takes a few minutes and all are free.
- One odd finding can be innocent. Three together is a pattern.
- The best agencies are easy to verify: a real name on the site, a real address or an honest home office note, local phone, slow and steady reviews.
Why this matters more for marketing than for other vendors
When you hire a plumber, you can see whether the leak stopped. When you hire a marketing agency, you are trusting them with your Google listing, your website and your reviews, and you may not know for months whether they did real work or risky work. An agency that cuts corners on its own listing is telling you how it will treat yours.
In October 2026 we looked closely at the agencies that show up for SEO searches in Carrollton, Frisco, Plano and Dallas. We checked each one's listing, address, phone, reviews, state filings and website. Over half had at least one serious problem. Several had three or more. None of what we did required a paid tool. You can run the same checks on anyone pitching you.
1. The business name on the Google listing
Open the agency's listing on Google Maps. The name should be a company name, not a search phrase. "Frisco SEO Company," "Plano Website Design" and names that end in "Dallas SEO" when the business is not in Dallas are keyword stuffing. Google's rules say the name must match the real world name on signage and paperwork. An agency that breaks that rule on its own listing is likely to do the same on yours, and the suspension that follows takes your reviews with it.
2. The address
Copy the address from the listing and paste it into Google Maps on its own. Then look at Street View and the list of businesses at that address.
- A shipping store or mailbox place with a "suite" number is a mailbox, not an office.
- Dozens of businesses on one floor of an office tower usually means a virtual office: a mailing address and a rented meeting room by the hour.
- A house in a neighborhood may be a real home office, which is fine, but the listing should hide it as a service area business. A home address shown as a storefront is a rules problem, and it often means the owner does not understand the rules they are about to manage for you.
- A restaurant, a parking garage or a warehouse with no suite is a borrowed address.
For a real property check in Texas, the county appraisal district website (Dallas, Collin, Denton and Tarrant each have one) shows who owns the building and whether it has a homestead exemption, which marks it as someone's home.
3. The phone number
Look at the area code. A Dallas‑Fort Worth agency will usually have a 214, 469, 972, 817 or 682 number. An agency claiming a Frisco office with a Los Angeles, Kansas City or Florida number is often a national company renting a local address, or a one person shop somewhere else entirely. That is not always bad, but it should match what they tell you about where they are and who will do the work.
4. The reviews
Read the reviews, and then click on the reviewers. The patterns that showed up again and again in our research:
- Bursts. Seven reviews in one week, then nothing for a year.
- One review accounts. Reviewers whose only review ever is this agency.
- Near copies. Two reviews the same week that use the same unusual phrase.
- Keyword replies. Owner replies that repeat the agency's name and city in every sentence, written for Google rather than for the customer.
- Reviews about a rebrand. A cluster of reviews that all mention a name change at once is often a listing that was bought or merged.
Real review histories are uneven and boring: a few a month, different lengths, some with photos, some with a complaint and a calm reply.
5. The Texas business filing
Search the Texas Comptroller's franchise tax account lookup for the business name. It is free and takes a minute. You will see whether the entity exists, when it was formed, whether it is in good standing and whether it has the right to transact business in Texas. An agency that says it has been around since 2012 but has an entity formed last year, or a forfeited status, has some explaining to do. No entity at all under any similar name means you would be signing with a person, not a company.
6. The website
Three quick checks. First, is there a real person on the site: a name, a face, a short history? Agencies that hide who runs them tend to be white label resellers who send your work to someone else. Second, does the site say plainly where they are? "Serving DFW" with no city is a tell. Third, check the domain age with any free whois lookup. A site that claims fifteen years of local work on a domain registered last spring is not telling the whole story.
How to weigh what you find. One odd item can be innocent. Plenty of honest businesses have an out of state cell number or a thin review history. Three items together, like a keyword name at a mailbox address with a burst of one review accounts, is a pattern, and it is the same pattern we see on listings that later get suspended.
What good looks like
The agencies that passed every check had a few things in common. A normal business name. Either a real office you could walk into or an honest note that they work from a home office, with the address hidden and a service area shown. A local phone number. Reviews that trickled in over years. A state filing that matched the story on the website. And a founder's name and face on the About page.
That is the bar. It is not a high one. It is just the bar most agencies in our research did not clear. Hold anyone pitching you to it, including us. Our address, phone and who we are are on this site, and you are welcome to run every one of these checks on No Contract SEO.
Common questions
Is a home based agency a red flag?
No. Many of the best small agencies work from home. The flag is a home address shown as a storefront, or a rented mailbox dressed up as an office. An honest home office with a hidden address is fine.
What if the agency has great reviews but a mailbox address?
Ask them about it directly. Some will say they moved and forgot to update the listing. If the answer is vague, or they say it is normal, be careful. They will manage your listing with the same attitude.
Can I report a fake listing to Google?
Yes. On the listing, choose Suggest an edit, then Close or remove, and pick the reason. Google reviews these and often acts on them when the evidence is clear. It can take weeks.
Should I ask the agency for client references?
Yes, and ask for ones in your trade or your area. Then check those clients' Google listings with the same six steps. If the clients' listings have keyword names and mailbox addresses, you know what you would be buying.
