A Grays-based retailer asked us a question nobody had warned her to ask before signing with her previous agency: if she left, did the fifty blog posts they'd written over two years leave with them?
She genuinely didn't know the answer, and neither, it turned out, did the account manager she asked. That uncertainty alone is the real problem here, more than any specific horror story.
It's a strange gap in how most SEO relationships get set up. Businesses will negotiate hard over monthly price, over deliverables, over contract length, and then barely think about what happens to the actual output of two years of paid work the day the relationship ends.
The Ownership Question Comes First
This should be settled before you ever sign a contract, not after you've decided to leave. Most reputable agencies will state clearly that content created for your site belongs to you once paid for, published on your domain. Some contracts, though, include clauses that retain certain rights, or restrict reuse, or even threaten removal of content if the relationship ends. Read this section of any contract carefully, because it rarely gets explained verbally during the sales process.
If a contract is vague or silent on this point, ask directly, in writing, before signing. Get the answer in an email you can refer back to later.
It's a question most people feel slightly awkward asking during a sales process that's otherwise going well. Ask it anyway. A good agency won't flinch, and a vague answer tells you more than a confident one ever could.
We put this in writing for every new client now, as a single short clause, precisely because we'd rather have the conversation at the start, when nobody's emotionally invested in a particular outcome, than at the end, when a parting on bad terms makes everyone less reasonable than usual.
What Actually Happens in Practice
In most cases we've seen, content stays published on the client's domain regardless of who wrote it, simply because removing dozens of indexed, ranking pages would hurt the agency's own case study more than it helps anyone. But "most cases" isn't "all cases," and we've heard of agencies who, out of spite after an acrimonious parting, pulled content or let hosting lapse on blog subdomains they controlled.
A Billericay garden centre once discovered, three months after switching providers, that an entire seasonal content hub had vanished because it had been hosted on a subdomain the old agency controlled rather than the client's own domain. That's an avoidable disaster, but only if you catch the structural issue beforehand.
They lost two Christmas campaigns' worth of ranking pages overnight, right before their busiest trading period. Rebuilding that visibility from scratch took most of the following year.
The garden centre's owner told us afterwards that nobody had ever explained to her, in plain terms, the difference between her own domain and a subdomain the agency controlled. To her it had all just looked like "the website." That gap in understanding, more than any bad intent on anyone's part, is what caused the loss.
Why Domain and Hosting Setup Matters So Much
Content written for a page on your own primary domain is almost always safe, because removing it would mean editing your actual website, which the old agency has no ongoing access to do once the contract ends and logins change. Content hosted on an agency-controlled subdomain, or worse, on a page the agency built and hosts separately, is far more vulnerable.
- Content on your own domain, your own hosting: generally safe
- Content on an agency-managed subdomain: check this carefully
- Content on a page you don't have direct admin access to: a real risk
If you're not sure which category your site falls into, ask the agency directly where the content actually lives, technically, not just where it appears to a visitor. Most business owners have never checked this and genuinely assume everything sits on their own domain by default. It doesn't always.
A five-minute check settles it either way: look at the web address of a blog post. If it sits under your main domain, yourbusiness.co.uk/blog/something, for instance, rather than a separate address entirely, you're almost certainly safe. If it looks structurally different from the rest of your site, ask why.
It's worth doing this check even if everything currently feels fine with your existing agency. Structural issues like this sit dormant for years without causing any visible problem, right up until the day a relationship ends and you suddenly need the access that was never properly set up. A ten-minute check now genuinely beats a stressful, scrambled discovery later, when it matters most and time is tightest.
Who Can Edit It Afterwards
Ownership of the words is one thing. Practical ability to edit them is another. If a new SEO provider wants to update an old blog post, they need CMS access, not just goodwill from the previous agency. Make sure your departing agency hands over full admin credentials, including to any plugins, image libraries, or scheduling tools tied to that content, before the relationship officially ends.
A Checklist Worth Running
Before you finalise a switch, confirm you have working admin access to your CMS, your analytics, your Search Console property, and your Google Business Profile. We ask new clients for this list in the first week, and it's surprising how often at least one item is still sitting with a previous provider, sometimes forgotten rather than withheld deliberately.
Search Console access trips people up more than any other item on that list, oddly enough, probably because it's the least visible of the four day to day. A business owner logs into their website and their analytics regularly. Search Console tends to get set up once and never touched again, which makes it easy to lose track of entirely.
If you genuinely can't locate it, there's usually a way to verify ownership of your own domain directly with Google and set up a fresh property, though it means losing the historical data tied to the old one. Not ideal, but far better than operating blind going forward.
Quality Varies, and That's Worth Assessing Too
Not all inherited content is worth keeping as-is. Some of it will be genuinely good and worth preserving. Some will be thin, generic, or written purely to hit a word count rather than answer a real question a customer might search for. Part of onboarding with any new SEO provider should involve an honest audit of what exists already, rather than assuming everything inherited is either all good or all bad.
We've kept plenty of a previous agency's content untouched because it was simply fine, and rewritten other pages entirely because they weren't serving anyone, least of all the client paying to host them.
What to Do Before You Switch
Download or export everything you can — a list of published URLs, any content calendars, keyword research documents, internal linking notes. Even if you don't end up needing all of it, having it saved means nothing is lost to a dispute, a lapsed login, or simple administrative chaos during a transition.
We keep a simple handover document for every client relationship that ends, regardless of why it ended, purely so nothing gets lost in the shuffle. It takes twenty minutes to prepare and saves weeks of frustration on the other side if the client later wants a new SEO provider to pick things up cleanly.
The Bottom Line
Content an agency writes for you should, in almost every reasonable setup, remain yours and remain published after you leave. But "should" and "does" aren't always the same thing, and the difference usually comes down to boring structural details — who hosts what, who controls which logins — decided long before anyone was thinking about leaving at all.
