How to Evaluate Your SEO Agency: A Simple Checklist for Owners
You pay an SEO agency every month. You get a report full of graphs. But you still can't say whether it brought you a single customer. This checklist shows you how to evaluate an SEO agency in about 15 minutes a month, without learning SEO yourself.
Why It's Hard to Evaluate an SEO Agency From Its Reports
When a founder asks me to look at their SEO agency, the report usually looks the same. Rankings for 40 keywords, a traffic graph going up and a list of tasks marked "done". What's missing is the one thing the owner actually cares about: did any of this bring in enquiries?
It isn't always the agency's fault. Many owners never told the agency what a good lead looks like, so the agency reports whatever is easy to measure. Either way, you need a simple way to check your SEO results and whether the monthly retainer is paying for itself. That's what this page gives you.
Start with one question. Ask your agency: "How many enquiries came from Google search last month, and which pages did they come from?" If they answer in plain words with a number, that's a good sign. If they steer the talk back to rankings and traffic, read on.
5 Checks to Evaluate Your SEO Agency
Is the website technically healthy?
This is the technical SEO part. If Google can't load or read your site properly, nothing else matters. You don't have to do this work yourself. However, you do need to know someone is doing it.
- Speed: Your site should load quickly on a phone. Ask for the Core Web Vitals report from Google Search Console.
- Mobile: Google looks at the mobile version of your site first. Open your site on your phone and try filling the contact form. If it's painful for you, it's painful for your customers.
- Errors: Broken pages, pages blocked by mistake and sitemap errors should be fixed in days, not months. One wrong line in your robots.txt file can hide your whole site from Google.
Are they doing what they promised?
First, take out the proposal they sent before you signed. Then compare it with what has actually happened since.
- Milestones: If the audit was due in month one and content in month two, you should be able to see both. If month-one work is still "in progress" in month four, that's a problem.
- Speed of fixes: When something breaks, how long does it take them to fix it? A few days is normal. Weeks, again and again, is not.
- Who spots problems first: A good agency tells you about an issue before you notice it. If you're always the one finding problems, they aren't watching closely.
Is the content actually useful?
Google has become good at telling the difference between content written by someone who knows the business and content written to fill a monthly quota.
- Does it sound like you? Read your last three blog posts. Could a competitor publish them by just changing the logo? If yes, they won't build trust with buyers or with Google.
- Right keywords: Ranking for "what is SEO" is useless if you sell industrial pumps. Ask which posts target the words your buyers type when they are ready to call someone. Good keyword research starts with search intent: what the buyer wants at that moment.
- Your input: The best content comes when you share real customer questions and examples, and the agency shapes them for search. If they never ask you anything, the content will stay generic.
Can you see the real numbers?
Most owners skip this part when they evaluate an SEO agency, even though it's the easiest to check.
- Own your accounts: Google Analytics and Search Console should be set up under your company email, with you as the owner. The agency gets access, not ownership.
- Leads, not just traffic: "Traffic is up 20%" means little if the visitors are students or from another country. Ask where the visitors came from and what they did on the site.
- What's next: Every monthly report should end with what they will change next month, and why.
Are the backlinks clean?
Links from other websites help your rankings. On the other hand, bad links can hurt them, and cleaning up after cheap link building takes months.
- Where they come from: Links should come from real industry sites, directories and publications that make sense for your business, not random blogs on unrelated topics.
- No shortcuts: Paid link packages and private blog networks can get your site penalised. No ranking jump is worth that risk.
3 Numbers to Evaluate Your SEO Agency Every Month
If you only have 15 minutes a month to evaluate an SEO agency, look at these three numbers. They tell you more about your SEO ROI than a 20-page report.
Watch out for easy rankings. It's easy to rank for words nobody buys from. Being #1 for "what is digital marketing" won't bring a consulting firm a single client. Ask your agency to show you rankings only for words linked to your services.
5 Signs It's Time to Change Your SEO Agency
When you evaluate an SEO agency over a few months, watch for these red flags. One bad month is normal. However, two or more of these together means it's time to look elsewhere. Before renewing the retainer, have a marketing consultant for small business check whether SEO is even your best channel.
