# How to choose an ecommerce SEO agency: questions to ask

> To choose an ecommerce SEO agency, look for concrete experience with store-specific issues like faceted URLs, category pages and product structured data, plus a 90-day plan, clear metrics and transparent reporting. Avoid agencies that guarantee rankings, hide their methods or sell link packages by the count.

## How do you choose an ecommerce SEO agency?

When choosing an ecommerce SEO agency, first check its experience with problems specific to online stores: category and product pages, faceted URLs, product structured data and site migrations. Then ask what it will do in what order, which metrics define success and whether it explains every change and the reason behind it. Walk away from anyone who guarantees rankings.

SEO is one of the slowest marketing channels to show results and one of the hardest to audit. A wrong agency choice often only becomes clear months later. The questions below are meant to help you separate the right agency from the wrong one in the first call.

## Why is ecommerce SEO different from general SEO?

A corporate site has hundreds of pages; an online store can generate tens of thousands of URLs through filters, variants and pagination. Discontinued products, seasonal categories, price and stock changes all come into play. That makes ecommerce SEO a three-layer job: controlling crawling and indexing (canonicals, filters, pagination), matching category and product pages to search intent, and handling product structured data and shopping surfaces like Merchant Center. Writing blog posts is a small part of it.

If you want to see the steps from your side, our guide on [how to do ecommerce SEO](/en/blog/how-to-do-ecommerce-seo) walks through them. Knowing what you're asking about makes the conversation with an agency much easier.

## What questions should you ask an SEO agency?

Google's "Do you need an SEO?" guide lists questions to ask: examples of past work, whether they follow Google Search Essentials, what results to expect and over what timeframe, how success is measured, their experience in your industry and whether they'll share every change with the reasoning. Adapted for ecommerce, this is the list we use:

1. What technical problem did you solve on an ecommerce site of similar size, and which metric showed the result?
2. What will you do in the first 90 days, and how do you set priorities?
3. How do you handle faceted category pages and variant URLs?
4. How do you approach product structured data and the Merchant Center side?
5. Where and how do you log every change you make?
6. If you produce content, who writes it and where does product knowledge come from?
7. How do you approach link building?
8. When the contract ends, which files, access and reports stay with us?

A good agency answers these concretely and asks questions about your business in return. Google makes the same point: a good SEO is curious about what makes your business unique, who your competitors are and how customers find you.

## What are the warning signs of a bad SEO agency?

The same Google guide spells out several warning signs. No one can guarantee a number one ranking on Google, and you should be wary of firms that claim a "special relationship" with Google or offer "priority submit". Agencies that won't explain what they intend to do, or talk about secret methods, belong in the same category.

Links deserve extra attention. Google's spam policies include link spam and scaled content abuse, and techniques that break those policies can push your site down in search or remove it from the index. Google also reminds site owners that they're responsible for the actions of the companies they hire. Be careful with any agency selling "X backlinks a month" as a package.

## An agency comparison table

Use this table to score the agencies you talk to on the same criteria:

| Criterion | Strong sign | Weak sign |
|---|---|---|
| Ecommerce experience | Concrete examples on filters, canonicals, product schema | Only blogs and keyword lists |
| Planning | Prioritized 90-day plan based on a diagnosis | The same package for every client |
| Measurement | Organic revenue, category traffic, indexed pages | Ranking screenshots only |
| Transparency | Change log with reasons | "Our method is a secret" |
| Link building | Content and PR led, quality focused | Link packages sold by monthly count |
| Promises | Realistic timeline | Ranking guarantees |
| Access | Staged, logged access | Full admin rights on day one |

## What access should you give an SEO agency?

Google recommends granting only read access to Search Console during the audit stage. Search Console has different permission levels, including owner, full user and restricted user, and a restricted user is enough for an agency still pitching. Widen access once work starts, but always stay the property owner. The same applies to GA4, Google Ads and your store admin: accounts are opened in your name and the agency is added as a user.

## When should you expect results from an SEO agency?

Google's SEO starter guide says some changes take effect within hours while others can take several months, and that you'll usually want to wait a few weeks to judge whether your work helped. In ecommerce, a practical expectation looks like this: technical fixes show up in Search Console within the first weeks (indexed pages, crawl errors), while traffic gains on category pages take longer. Example: for a store with 200,000 TL in monthly organic revenue, expect the first month's report to show technical health metrics rather than revenue growth.

So in the contract, look for commitments on process and measurement, not rankings: which work is delivered when, and which metrics are reported each month.

## What should you look for in an SEO agency proposal?

When you put proposals side by side, look at three things beyond price. First, scope: the proposal should state clearly which of technical audit, category and product page optimization, content and link building are included. Second, implementation: does the agency only deliver a recommendations report, or does it make the changes on the site itself? In ecommerce, recommendations often sit in a development queue; if it isn't clear who implements them, the report ends up in a drawer. Third, the pricing model: a monthly retainer, a project-based audit or a mix. Whichever you choose, the list of deliverables matters more than the fee.

## Ecommerce agency or specialist SEO agency?

This is a trade-off too. A specialist SEO agency can be strong on technical depth but won't see your ads, feed and conversion side. An [ecommerce agency](/en) treats SEO together with Google Shopping, the product feed and site conversion; the same product title, for example, works in organic search and in a Shopping ad. If your organic traffic is low and your ad budget is high, the joined-up view tends to add more value. If your platform is technically complex and a large migration is coming, deep technical SEO experience should come first.

## Key takeaways

- Ecommerce SEO differs from general SEO because of filters, variants, product schema and category pages; the agency needs concrete experience with them.
- In the first call, ask for a 90-day plan, the metrics they'll report and how changes are logged.
- Ranking guarantees, secret methods and link packages sold by count are red flags.
- Give read-only access at the audit stage and always keep ownership of your accounts.
- Results arrive in stages: technical health first, then organic traffic and revenue.

## FAQ

### Can an SEO agency guarantee rankings?

No. Google states plainly that no one can guarantee a number one ranking on Google. Be wary of agencies that guarantee rankings, claim a special relationship with Google or promise priority submission. Ask instead for clear commitments on process, delivery timeline and the metrics they will report.

### What should you ask an ecommerce SEO agency in the first call?

Ask which technical problem they solved on a similar ecommerce site and which metric showed the result, what their first 90 days look like, how they handle faceted category and variant URLs, how they approach product structured data, how they log changes and which files stay with you when the contract ends.

### What access should you give an SEO agency?

Google recommends granting only read access to Search Console during the audit stage. Widen permissions gradually once work begins, but always remain the owner of Search Console, GA4 and your store admin. Add the agency as a separate user so you can remove access easily if the relationship ends.

### How long does ecommerce SEO take to show results?

According to Google, some changes take effect in hours and others take several months. In ecommerce, the effect of technical fixes usually shows in Search Console within the first weeks, while traffic and revenue gains on category pages take longer. Expect the first monthly report to focus on technical health rather than revenue.
