SEO agencies differ more than their service pages suggest. Some do nothing but search, some lead with content and digital PR, and some fold SEO into a wider program of paid media and web work. The right partner depends on whether you need local visibility, national content, technical fixes, or SEO tied to the rest of your marketing. Below are seven agencies worth knowing, with the facts each company publishes about itself.

## How to choose an SEO agency

- **Decide what kind of search you need.** Local visibility, national content and technical fixes call for different strengths.
- **Ask how they measure success.** Leads, calls and revenue from search matter more than rankings for terms nobody buys from.
- **Ask about AI search.** Find out how they handle visibility in AI answers as well as classic search results.
- **Check who implements changes.** Some agencies recommend fixes and leave the work to your developer; others make the changes.
- **Look at how SEO connects to the rest.** Search traffic converts better when the website, tracking and follow-up are built for it.

## How we chose these agencies

## Frequently asked questions

### What does an SEO agency do?

An SEO agency improves how your site appears in search results and, increasingly, in AI-generated answers. The work usually covers keyword research, technical fixes, on-page changes, content and links, and for local businesses, Google Business Profile. Some agencies only recommend changes, while others make them, so ask which you are paying for before you compare proposals.

### Should I choose an SEO-only agency or a full-service agency?

An SEO-only agency can go deeper on search, which suits companies with a large site or a strong in-house team for everything else. A full-service agency can connect SEO with the website, paid media and follow-up, which suits businesses that want one team accountable for leads. Decide which gap you are actually trying to fill first.

### Is Commerce Media Group ranked first on this list?

No. We publish this list, so we list ourselves first and label it as our agency, and the other agencies follow in alphabetical order. We have not scored or rated anyone. The facts about each company come from its own website, and the sources are listed at the end so you can check them yourself.

### How long does SEO take to work?

It depends on your site, your market and how much needs fixing. Technical and on-page fixes can help sooner, while content and authority build over months. Be cautious of guaranteed rankings or timelines. Ask an agency what it will change first, which numbers it will report, and what progress should look like at each review.
