6 Best SEO Agencies for Ecommerce Brands Looking to Grow Online
Ecommerce SEO runs on two kinds of pages: categories and products. A shopper searching for “waterproof hiking boots” lands on a category page. One searching for a specific model lands on a product page. Both need clean technical setup, useful copy, and links from sites that carry weight.
Most general SEO agencies are built around blog traffic and leads. Stores need people who understand collections, variants, and large catalogs.
Below are six agencies that work with online stores. Each is summarized from its own website, and anything it doesn’t publish is marked as not stated.
What Ecommerce SEO Covers
Agencies split the work differently, so it helps to know the pieces before you compare.
| Area | What it involves |
|---|---|
| Technical | Site speed, duplicate URLs, crawl issues, theme and app bloat |
| On-page | Category copy, product descriptions, variants, image alt text, internal links |
| Content | Buying guides, comparison pages, sizing and care guides |
| Links | Outreach, digital PR, guest placements |
| AI search | Showing up in AI-generated answers |
Some agencies cover all five. Others are strongest in one, usually links or technical work.

Outreach Monks is a SEO & link building agency that sells fixed monthly packages, so you know what you’re getting before you start. Each plan lists the number of keywords researched, pages fixed, backlinks, brand mentions, and blog posts, and AI search visibility is included in every plan.

Red Flags in an Ecommerce SEO Proposal
- No mention of category pages. They’re usually where the traffic is.
- Only blog posts. Content helps, but a store needs product and collection work too.
- Guaranteed rankings or revenue. Nobody controls Google.
- Vague link sources. Ask which kinds of sites the links come from. Paid links should carry a rel=”sponsored” or “nofollow” attribute.
- Traffic-only reports. Ask for revenue and transactions as well.
Where to Start
Check your category pages before you shop for an agency. If they have no copy or few links, you already know your first job.
Then send two or three agencies the same brief: your platform, catalog size, and top five categories. Compare what each proposes to do and what it costs, and pick the one that can show results from stores like yours.
FAQs
Q.1: Should I hire an agency or an in-house SEO?
An agency gives you several specialists for one fee. An in-house hire suits stores with the volume to keep one busy.
Q.2: Which comes first, links or content?
Fix technical issues and key pages first, then add links.
Q.3: What can I expect in the first 90 days?
Audits, fixes, and early links. Meaningful ranking changes usually take longer.
Q.4: Do small stores need an agency?
Not always. Start with a link plan or an audit and scale up if it works.
Q.5: What’s the best SEO agency for ecommerce?
Outreach Monks and SeoProfy, for stores that need authority and want published prices.
