How we score

Every number on this page is computed from public Google data on the date shown, not from opinion or payment. Rating is the business’s live Google star average. Review volume is how many customers have rated them, ranked against other Houston marketing agencies. Confidence weighs the rating by that volume, so a 4.9 from over a hundred people carries more weight than a 5.0 from a dozen. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much does a digital marketing agency cost in Houston? (2026)

Agency pricing in Houston varies widely by scope, from a single SEO audit to an ongoing multi-channel retainer. Only one agency on this page publishes a specific package price in the data we collected, so we list that alongside general guidance rather than inventing a full rate card.

Job	Typical price
Multi-channel retainer (Symphony Advertising’s published Ensemble package, 3-month minimum)	$2,250/month

Pricing shown is drawn directly from Symphony Advertising’s own published website copy, verified August 2026. Other agencies on this page do not publish fixed rates in the data we collected, so ask each one for a written quote scoped to your project.

Serving all of Houston

These agencies work with clients across Houston and the surrounding metro, from Downtown and Midtown to the suburbs served by remote and on-site teams alike.

Frequently asked questions

How did you choose these agencies?

We started from digital marketing agencies in Houston with a public Google presence, then ranked by rating, review volume, consistency and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Do these agencies specialize in specific industries?

Some do. Symphony Advertising focuses heavily on home-service and auto trades, while Illumination Marketing names healthcare, HVAC and med spa clients specifically. EWR Digital and ASTOUNDZ work across a broader mix of industries.

How much does a digital marketing agency cost in Houston?

Pricing depends heavily on scope and channels. Symphony Advertising publishes a $2,250/month package as one reference point; ask each agency on this page for a written quote scoped to your specific goals before committing.

The bottom line

EWR Digital is the safe default given its decades in Houston and the deepest review history on this page, while Symphony Advertising and Red Houston SEO Company are the highest-rated names if you want a leaner specialist. Get a written scope and timeline before signing with any of them.
