SEO Copywriting Agency
I used to think hiring an SEO copywriting agency was a set-and-forget fix. After burning budget on generic copy and missed deadlines, I changed everything.
What I’d do first
- Audit your existing content to understand your own gaps before you brief an agency.
- Ask to see a before-and-after of a page they have rewritten, including rankings and conversions.
- Run a test with one page before committing to a retainer.
- Ensure the agency’s writers understand search intent, not just keywords.
- Set up tracking in Google Search Console and a CRM to measure impact.
The path I'd take
If I were hiring an SEO copywriting agency today, I would not look at their portfolio first. I would look at my own content. Because no agency can fix what you do not understand about your own business. I would start with a [content audit](/content-audit/) to identify which pages have traffic but no conversions, and which have strong internal links but weak copy. Then I’d map those pages to search intent. For example, a service page targeting 'SEO copywriting agency' needs to answer what you do, who it is for, and why you are better than alternatives — not just a list of services. Once I had that map, I would write a brief for a single [landing page](/what-is-a-landing-page/) and pay the agency to rewrite it. That test tells me everything: their ability to align with intent, their tone, and whether they deliver on time. I’d measure the page’s performance in Google Search Console for three months. Only then would I scale to more pages. Too many people skip the test and regret the retainer.
I also insist that the agency uses a shared document from the start — not a handover with no collaboration. I have seen too many briefs that read like a client throwing requirements over a wall. The best results I have had came from a back-and-forth: I supplied the internal data (conversion rates, sales team feedback), the writer supplied the structure and wording. We iterated. That process sounds slow, but it saved me weeks of revisions later.
Finally, I ask the agency how they prioritise keywords. If they lead with search volume alone, I push back. Volume without commercial intent, like 'SEO copywriting agency', is misleading. I want them to consider relevance and competition too. I once saw an agency target a high-volume keyword that had nothing to do with the service — traffic went up, but the bounce rate hit 90%. That was a lesson. Now I map keywords to stages of a buyer’s journey and ask the agency to do the same. A solid [SEO content strategy](/seo-content-strategy/) should connect each page to a specific business goal, not just a search volume target.
Watch-outs
Here is what I wish someone had told me before I hired my first SEO copywriting agency. The biggest watch-out is agencies that promise rankings. No agency can guarantee a top three position, and if they do, they are either lying or about to use tactics you will regret. Another watch-out: agencies that write for Google before they write for humans. I have received drafts packed with keywords, but the sentences were unreadable. Google now penalises that kind of writing anyway.
Another watch-out is the agency that does not ask for access to your analytics. If they cannot see your current traffic, conversions, and user behaviour, how can they know what to improve? I once hired a writer who never once checked my site. The draft could have been for any business. It was generic. I paid for that mistake.
Also watch for agencies that treat SEO copywriting as a one-off job. A page needs to be updated as data changes. I now insist on a quarterly content audit of every page they have written. The agency should be willing to refresh content. If they are not, move on.
Finally, watch for slow turnaround times without communication. I had an agency miss three deadlines because they were overbooked. That cost me a market opportunity. Now I put clear delivery milestones into the contract. And if the agency cannot explain their [on-page SEO](/on-page-seo/) decisions in plain English, that is a red flag. You need to understand why they are using a particular heading structure or meta description.
What I got wrong
I made two big mistakes with SEO copywriting agencies. First, I assumed that because an agency had a good website, their writers would produce good copy for mine. That was naive. I hired an agency that ranked well for 'SEO copywriting' but their sample work was full of fluff. The copy they delivered for me was no better. I learned to demand samples relevant to my industry, not just their best work.
Second, I thought I could hand over the strategy entirely. I paid a retainer for six months and stepped back. The result? Pages that matched keywords but did not convert. I had not given them my customer data — the questions prospects asked, the objections they raised. The copy missed the mark. Now I see that the agency is a partner, not a magic wand. I need to invest time in briefings and reviews.
Another wrong move: I prioritised speed over quality. I needed content fast, so I chose an agency that churned out blog posts at scale. But the posts were shallow, and Google did not rank them. Traffic barely moved. I would have been better off writing five solid pages myself than publishing fifty mediocre ones. This aligns with Google’s emphasis on helpful, people-first content. The [SEO copywriting](/seo-copywriting/) I now value is patient: research, draft, test, refine.
Finally, I underestimated the importance of [internal links](/internal-links-seo/). I used to think that was my job after the copy came in. But the agency should suggest where new pages link to existing ones. I now include a request for suggested internal links in the brief. It saves time and strengthens the site. Looking back, I should have chosen an agency that specialises in [SEO content writing](/seo-content-writing/) rather than a general copywriting shop. The difference in quality and results was dramatic.

Quick answers
How do you vet an SEO copywriting agency?
Ask for a sample rewrite of one of your own pages, including a brief that explains keyword targeting and intent. Check their client references for retention rates and ask about their process for updating content three months after publication. Avoid agencies that promise specific ranking positions.
Should I hire an SEO copywriting agency or a freelancer?
An agency works well when you need multiple page types and ongoing optimisation. A freelancer can be better for niche topics if you find someone with domain expertise. I have used both. The deciding factor is whether the writer understands your market well enough to write without hand-holding every week.
How much does an SEO copywriting agency charge?
Expect £100–£300 per page for a standard service page, and £200–£500 for a comprehensive landing page with keyword research and internal linking. Retainers for ongoing work range from £2,000 to £10,000 per month. The price often reflects the amount of research and iteration the agency includes.
