Top 7 Mistakes Ecommerce Brands Make When Hiring An SEO Agency

TL;DR

Choosing the right ecommerce search engine optimization agency can make or break your brand’s growth trajectory. Many ecommerce businesses fall into the same traps, prioritizing low cost over expertise, chasing vanity metrics, or hiring generalists who don’t understand the technical demands of ecommerce SEO. This post breaks down the seven most damaging mistakes brands make when hiring an SEO agency and how to avoid them so you can choose a true long-term growth partner.

——

As I’ve touched on in other posts, hiring an SEO partner isn’t just a marketing decision; it’s a strategic investment in your brand’s long-term visibility and profitability. The right agency can help you dominate search, lower your acquisition costs, and scale sustainably. The wrong one can waste tens of thousands of dollars, damage your rankings, and set your business back months or even years. Scary, right?

I wrote this post so you can understand the seven most common, costly mistakes ecommerce brands make when hiring an SEO agency and what to look for instead.

The Biggest Mistakes Brands Make When Hiring an Ecommerce SEO Agency

The biggest mistakes I see ecommerce brands make when hiring an SEO agency include prioritizing low cost over proven value, overlooking the need for specialized ecommerce experience, falling for unrealistic performance guarantees, and failing to establish clear, revenue-focused goals from the start.

Let’s dive into each one to give you some more context and information.

Mistake #1: Prioritizing Low Cost Over a Value-Driven SEO Strategy

Despite popular belief, ecommerce SEO is not a commodity; it’s a high-impact, high-leverage growth channel that requires technical expertise, data analysis, and strategic alignment with your revenue goals. Yet many brands I talk with still select their agency primarily based on price. It’s a slippery slope to go down.

Cheap SEO agencies are cheap for a reason. The four main reasons for being cheap often include the following:

• Outsourcing all work to low-cost freelancers or team members with zero accountability
• Creating category, product page, and blog content with AI with little to no human oversight
• Using outdated or black-hat link-building tactics that are fast and easy to put in place
• Skipping critical technical audits or conversion analyses
• Delivering reports that look good based on vanity metrics like keyword rankings, but don’t connect to revenue

When it comes to SEO and marketing in general, you truly get what you pay for. A $500/month package might sound appealing, but if it fails to move the needle, or worse, triggers a Google penalty, you’ll lose far more than you save.

A value-driven agency focuses on ROI, not just keyword rankings. They’ll align SEO activities to your bottom line: organic sales growth, improved conversion rates, and long-term brand visibility.

Mistake #2: Ignoring Specialized Ecommerce Experience

Believe it or not, ecommerce SEO is fundamentally different from general SEO. You’re not just optimizing blog posts or service pages; you’re managing dynamic product catalogs, thousands of URLs, and complex site architectures that can confuse search engines if handled incorrectly. This is one of the main reasons why we chose to specialize in an industry.

Brands that hire a generalist SEO agency or an agency that isn’t at least 90% focused on the ecommerce industry are just asking for trouble.  A generalist SEO might know how to optimize a small business website, but not how to:

• Manage faceted navigation and prevent duplicate content
• Implement structured data and product schema for rich results
• Optimize category pages for high-intent keywords
• Handle seasonal inventory changes without disrupting SEO performance
• Balance UX, conversion rate, and crawl efficiency

And the list goes on and on.

The best ecommerce SEO agencies that I’ve come across are fluent in the nuances of Shopify, BigCommerce, Magento, and WooCommerce. They fully understand how these platforms handle canonical tags, JavaScript rendering, and structured data differently. Before moving forawrd with any generalist agency, ask them for specific examples of ecommerce sites they’ve optimized and measurable results they’ve achieved to get a handle on their actual capabilities.

Mistake #3: Falling for Unrealistic Promises and “Guaranteed Rankings”

I’m still amazed by how many potential clients I speak with who say something like “Agency XYZ said I should be ranking for these keywords in the next 30 days”. If you hear that, run as fast as you can the other way.

If you’re unfamiliar with how search engine algorithms work, they are constantly updating and evolving. Google alone updates its algorithm thousands of times per year. If your agency is telling you they can guarantee rankings, if they know someone at Google who can pull some strings for them, if they have a Google SEO rep who feeds them insider information, etc. they are flat out lying to you. None of these is a real thing, and they never will be.

Reputable agencies focus on what can be controlled:

• Building a clean, technically sound foundation
• Creating high-quality, incredibly helpful, search and AI-optimized content
• Earning authoritative backlinks through legitimate outreach
• Measuring the impact through organic traffic and sales

At the end of the day, great ecommerce SEO takes time. We tell clients that they can typically start seeing results in 3ish months and they will start to see the best version of our results around months 6-9. From there, everything really starts to compound and results climb like crazy. A transparent partner will tell you this upfront, explain their process, and provide benchmarks along the way.

The right promise isn’t “#1 in Google”. It’s: “We’ll help you grow organic revenue through sustainable SEO that compounds over time”. See the difference?

Mistake #4: Focusing on Vanity Metrics Instead of Revenue

Rankings and traffic are not the same as revenue. Don’t get me wrong, they are great leading indicators that the work is starting to move the needle, but if revenue is not following shortly thereafter, it can become a problem in a hurry.

Truth is, many agencies focus on vanity metrics because they’re easy to report but don’t tell the full story.

Examples of vanity metrics include:

• Ranking for irrelevant or low-intent keywords
• Increasing raw traffic without conversions
• Earning backlinks from unrelated or low-quality domains

Ecommerce SEO success should be measured by business outcomes. Smart brands focus on KPIs like:

• Organic conversion rate
• Revenue from organic traffic
• Average order value (AOV) from organic
• Customer lifetime value (CLV) from organic

A great example of this is an ecommerce brand selling fitness gear. They don’t directly benefit from ranking for “home workout ideas”; they benefit from ranking for “buy resistance bands online” or “best adjustable dumbbells”.

A strong agency will map every keyword and content asset to your buyer’s journey and ensure SEO performance translates into actual profit.

Mistake #5: Accepting Vague Communication and Poor Reporting

I’ve touched on this in other posts, like this one, but a healthy agency relationship is built on full transparency. Unfortunately, many brands get stuck with agencies that provide generic monthly reports filled with meaningless charts and no context. I’ve looked at some of these reports and they are bad.

Here’s what poor communication looks like:

• Reports focused only on rankings or impressions
• No clarity about why metrics changed
• No discussion of next steps or priorities
• Unclear ownership or accountability

Instead, expect:

• A dedicated account manager who knows your brand and goals
• Monthly or biweekly strategy calls that connect SEO actions to ROI
• Reports that show progress against business metrics (revenue, orders, conversions)
• Clear explanations of every deliverable: what’s been done, why, and what’s next

The very best agencies are proactive, not reactive. They tell you what they’re working on and why it matters to you and your business. They take enough time to help you interpret the data and make informed decisions. And most importantly, they make you feel like a partner, not just another account they need to check off on their list.

Mistake #6: Getting Locked into Inflexible, Long-Term Contracts

This one makes me really mad. I see way too many brands sign 12- or 24-month contracts only to realize after 90 days that the agency isn’t delivering. Guess what… this is why they tie you into those kinds of contracts to begin with.

This mistake is one of the most costly mistakes in ecommerce marketing. Long, inflexible contracts benefit the agency, not the client. They can trap your brand in a cycle of poor performance and wasted budget for a year or two with no way out.

Instead, you should be looking for the following:

• A 3 – 6 month initial engagement with performance checkpoints (we work on rolling 30-day agreements)
• A 30-day out clause if goals aren’t being met
• Clear documentation of ownership over assets (content, data, links, etc.)

The best agencies are confident enough in their process and ability to deliver results that they don’t need to lock you in. They’ll earn your business month after month through results and trust, not legal fine print.

Mistake #7: Failing to Vet the Agency’s Own SEO and Processes

Lastly, before you hire any SEO agency, take a close look at the agency’s own SEO performance. If they can’t rank in the top 5 for terms like “ecommerce SEO agency” or “Shopify SEO expert”, what makes you think they can get you ranking for your most important keywords?

Total… red… flag.

An agency’s online footprint tells you a lot about its credibility:

• Do they publish in-depth SEO resources or case studies?
• Do they rank for relevant terms in their niche?
• Do they have consistent content output and backlinks?

Beyond rankings, vet their process:

• How do they conduct technical audits?
• What does the first 30-60-90 days look like?
• How do they prioritize quick wins vs. long-term fixes?
• What is their offboarding process, and do you retain all assets and data?

Asking these questions ensures you’re partnering with professionals who practice what they preach and who won’t leave you stranded if the relationship ends.

Additional Questions to Ask Before You Hire

Before you sign any agreement, here are some other things that you should be thinking about and asking your agency for:

Can you share ecommerce case studies with measurable results?

If you can’t find case studies on their website, it’s okay. Maybe their clients don’t allow them to post them. If they don’t, ask for them and look for proof of revenue growth, not just keyword rankings.

What platforms have you worked with most (Shopify, BigCommerce, Magento, etc.)?

If you run on Shopify, you want to know that they have deep platform experience. This kind of experience saves time and prevents technical missteps.

What’s your process for conducting an ecommerce SEO audit?

Their process should include getting access to your Google Analytics, Google Search Console, running a crawl of the website, and should include technical, content, and link components.

How will you tie SEO efforts back to our bottom line?

Ask for a sample report with their client’s name removed. You’ll want to make sure that they have revenue-based reporting place.

Who will be our main point of contact, and how often will we meet?

They should be able to give you an idea of who your main point of contact will be if you choose to engage with them in the next 30 days. You’ll also want to ensure that their communication cadence directly impacts success.

What happens if we want to end the contract early?

They should be able to tell you exactly how they wind down work, how they transition back to you or another agency, etc. Transparency here protects your assets and your budget.
