I’ve been working in SEO since 2014, and I’ve seen every trick in the book.
I’ve watched brilliant agencies deliver real results for clients, and I’ve seen cowboys charge thousands for work that actively damaged businesses.
The worst part? Most business owners don’t know the difference until it’s too late.
They’ve signed a 12-month contract, paid thousands upfront, and six months later their traffic hasn’t budged – or worse, they’ve been hit with a Google penalty.
This guide shares the red flags I’ve learned to spot over a decade in the industry.
These aren’t theoretical warnings – they’re based on real situations I’ve encountered working with businesses across the UK, particularly in competitive sectors like vehicle rental and automotive services.
The “Guaranteed Rankings” Promise
This is the biggest red flag in SEO, and somehow it’s still everywhere.
Here’s what you need to understand: no legitimate SEO agency can guarantee specific rankings. Google’s algorithm uses over 200 ranking factors, and it changes constantly.
Any agency promising “first page guaranteed” or “number one ranking for [your keyword]” is either lying or planning to use tactics that will get you penalised.
I’ve seen this play out dozens of times. The agency delivers rankings – temporarily – using black hat techniques like private blog networks or paid links. Your site climbs to position 3 or 4, you’re thrilled, and then Google’s next algorithm update hits.
Your rankings don’t just drop – they disappear entirely. Your domain gets penalised, and recovery takes months or years.
What legitimate agencies say instead: “We’ll work to improve your rankings through proven white hat methods, but we can’t guarantee specific positions. Here’s what we’ve achieved for similar clients, and here’s our typical timeline for results.”
Notice the difference? Honesty about limitations, evidence of past success, realistic timelines.
The Absurdly Cheap Monthly Retainer
If an agency is offering “full SEO services” for £200-300 per month, walk away.
Professional SEO takes time. A proper technical audit alone requires 5-10 hours of skilled work. Content creation, link building, keyword research, on-page improvements, reporting – it all adds up.
An agency charging £250/month is either cutting corners you can’t see, or they’re farming your work out to inexperienced freelancers who don’t understand Google’s quality guidelines.
I learned this the hard way early in my career. A vehicle rental client came to me after paying £195/month for six months to an agency that promised “everything you need.”
When I audited their site, I found automatically generated content, spun articles that barely made sense, and hundreds of low-quality directory links. We spent four months cleaning up the mess before we could even start proper SEO work.
What to expect instead: Good SEO in the UK typically costs £750-2,500+ per month depending on your industry, competition, and goals. Local businesses in less competitive areas might get solid work for £750-1,000.
National campaigns in competitive sectors? £2,000+ is normal.
If someone’s significantly cheaper than this, ask exactly what you’re getting. Often it’s just automated reporting and basic keyword stuffing – not real SEO.
The Vague Reporting and Metrics Games
Legitimate agencies show you clear, understandable results. Scam agencies bury you in meaningless numbers.
Red flag phrases in reports:
- “We’ve built 500 backlinks this month” (without showing you what sites or checking quality)
- “Your domain authority increased from 28 to 31” (DA is a third-party metric, not a Google ranking factor)
- “We’ve improved your social signals” (social shares don’t directly impact rankings)
- “Your site has 10,000 impressions” (without showing whether relevant keywords drove those impressions)
I once reviewed an agency’s reporting for a client who was paying £1,200/month.
The monthly report was 40 pages long, full of graphs and charts. It looked impressive. But when I dug into the actual data, I found:
- The “backlinks” were all from irrelevant foreign sites
- The traffic increase was from brand searches (which they weren’t creating)
- The “improved rankings” were for keywords nobody was searching for
The agency was generating impressive-looking reports that meant absolutely nothing for the client’s business.
What good reporting looks like: Clear data on rankings for keywords that matter to your business, organic traffic trends from Google Analytics, conversion tracking showing whether that traffic actually helps your business, and honest explanations when something isn’t working.
The Up-Front Payment Demand
Most legitimate SEO agencies work on monthly retainers. They’re confident enough in their work to let you pay month-to-month.
If an agency demands six or twelve months payment upfront, that’s a warning sign.
Why? Because they’re protecting themselves against you cancelling when you realise they’re not delivering results.
I’m not saying all long-term contracts are scams – some agencies offer discounts for 6 or 12-month commitments, and that’s fine if you trust them.
But if they won’t work with you month-to-month at all, or if they’re pushing hard for a large upfront payment, be cautious.
Reasonable approach: A 3-month minimum commitment is fair – SEO takes time to show results. Monthly billing with 30 days notice to cancel is standard. Modest discounts for longer commitments are fine. But being locked in for a year with no escape clause? That’s risky.

After seeing countless examples of poor SEO work, I got tired of watching business owners get burned.

Questions to Ask Before Hiring
Here are the specific questions I’d ask any SEO agency before signing a contract:
1. “Can you show me examples of results you’ve achieved for businesses in my industry?”
Look for specifics – ranking improvements for relevant keywords, traffic increases, conversion data if possible.
2. “What methods do you use for link building?”
Red flag answers: “We have a network of sites,” “We use automated tools,” “We can’t reveal our methods.”
Good answers: “We focus on digital PR and content marketing,” “We earn links through creating valuable resources,” “We build relationships with industry publications.”
3. “How long before I see results?”
Red flag: “You’ll see rankings improve in 2-4 weeks.”
Good answer: “Typically 3-6 months for meaningful improvements, though some quick wins might happen sooner with technical fixes.”
4. “What happens if I’m not happy after three months?”
Red flag: “You’re locked into the contract.”
Good answer: “We’ll review what’s working and what isn’t, adjust strategy, and if you want to cancel, you can with 30 days notice.”
5. “Who exactly will be working on my account?”
Red flag: Vague answers or “a team of specialists” without specifics.
Good answer: Names, experience levels, and which aspects each person handles.
The Reality of Good SEO
Here’s what I’ve learned after a decade working on client websites:
Good SEO is slow, methodical, and sometimes boring. There are no shortcuts. The agencies that deliver real results are the ones that:
- Take time to understand your business and audience
- Focus on improving your website’s actual value to users
- Build genuine relationships for link acquisition
- Create content that answers real questions your customers have
- Track meaningful metrics tied to your business goals
It’s less exciting than promises of “first page in 30 days,” but it’s what actually works.
The cowboys will keep promising quick wins because that’s what sells. But if you want sustainable results that survive algorithm updates and actually grow your business, you need an agency that’s honest about what SEO really requires.
What to Do If You’ve Been Scammed
Already working with an agency showing these red flags? Here’s what to do:
- Request detailed reporting immediately – Ask for specifics on what work they’ve done, which links they’ve built (with URLs), and which keywords they’re targeting.
- Run a backlink audit – Use Ahrefs or SEMrush to check what links have been built to your site. Look for spammy patterns, foreign language sites, or irrelevant directories.
- Check for penalties – In Google Search Console, look at your manual actions and see if there are any warnings.
- Review your contract – Check notice periods and cancellation terms.
- Get a second opinion – Have another agency audit what’s been done. Many will do this for free hoping to win your business.
If you find evidence of black hat techniques, you may need to disavow harmful links and potentially start recovery work.
It’s frustrating, but catching it early is better than letting it continue.
The Bottom Line on SEO Agencies
I wish I could say the SEO industry has cleaned itself up over the past decade, but the truth is there are still plenty of agencies out there making promises they can’t keep and using tactics that harm their clients.
The good news? There are also brilliant agencies doing excellent work, delivering real results, and treating their clients with honesty and respect.
You just need to know what questions to ask and which red flags to watch for.
If you’re starting your search for an SEO agency, take your time. Ask questions. Request case studies. Check reviews.
And remember – if something sounds too good to be true, it probably is.
