What to Look for When Hiring an SEO Agency

The SEO industry has a reputation problem. Too many businesses in Harrow, Watford, Ealing and across London have been burned by agencies that promised page 1 rankings, delivered monthly reports full of jargon, and produced zero actual enquiries.

As an SEO agency based in Harrow with 15+ years of experience, we have seen what works and what does not. Here are eight things to check before you hire an SEO agency — and the red flags that should make you walk away.

1. Do They Rank for Their Own Keywords?

This is the simplest and most revealing test. If an SEO agency cannot rank their own website for "SEO agency" + their location, why would they be able to rank yours?

Search Google for "SEO agency [their town]" and see if they appear on page 1. If they do not practise what they preach, find someone who does.

2. Can They Show You Real Results?

Ask for case studies with actual data — traffic numbers, ranking improvements, leads generated, revenue attributed. Not testimonials (which can be fabricated), but verifiable results from real clients.

A good agency will happily show you Google Analytics or Search Console screenshots from client campaigns. A vague agency will talk about "improved visibility" and "brand awareness" without any numbers.

3. Do They Explain What They Will Actually Do?

SEO is not magic. It is a defined set of activities: technical audit, keyword research, on-page optimisation, content creation, link building, and performance tracking. If an agency cannot clearly explain what they will do each month in plain English, they are either hiding a lack of substance or deliberately obscuring their process.

At Websposure, every client gets a documented strategy before we start, and a monthly report showing exactly what was done and what it achieved.

4. Do They Guarantee Rankings?

Red flag. No legitimate SEO agency guarantees specific rankings. Google's algorithm considers hundreds of factors, many outside any agency's control. An agency that guarantees "page 1 in 30 days" is either lying or using risky tactics that could get your site penalised.

What a good agency guarantees is a proven process, transparent reporting, and continuous improvement based on data.

5. What Is Their Contract Structure?

Avoid agencies that require 12-month contracts upfront. SEO does take time to show results (typically 3-6 months), but you should not be locked into a long contract before seeing any evidence of competence.

Look for agencies offering 3-month initial terms, then month-to-month. If they are confident in their work, they do not need to trap you in a contract.

6. Do They Understand Your Local Market?

If you serve Harrow, Wembley, Uxbridge or Watford, your SEO strategy needs to be different from a national campaign. Local SEO involves Google Business Profile optimisation, local citations, area-specific content, and review management — skills that a generic national agency may not prioritise.

Ask the agency about their local SEO experience specifically. Can they show you local ranking results? Do they understand your service area?

7. What Do Their Reviews Say?

Check the agency's Google reviews, Trustpilot profile, and any industry-specific review platforms. Look for patterns: do clients mention clear communication? Measurable results? Responsiveness? Or do reviews mention poor communication, missed deadlines and lack of results?

8. Will You Own the Work?

Some agencies create content, build links, and manage your Google Business Profile under their own accounts. If you leave, you lose everything they built. Make sure you own all content, have access to all accounts (Google Search Console, Analytics, Business Profile), and can take your work with you if you change providers.

How Much Should SEO Cost?

In the UK in 2026, realistic SEO pricing looks like this:

• £300-£500/month: Basic local SEO — Google Business Profile, citations, minimal content
• £500-£1,000/month: Comprehensive local SEO — technical fixes, keyword targeting, content creation, link building
• £1,000-£2,000/month: Competitive local or regional SEO — full content strategy, multiple area pages, active link building, reporting
• £2,000+/month: National or ecommerce SEO — high-volume content, competitive keywords, advanced technical SEO

Anything under £300/month is unlikely to produce meaningful results. SEO requires real work — research, writing, technical implementation, outreach — and that work takes time from skilled people.

Frequently Asked Questions

How do I know if an SEO agency is legitimate?

Check their own Google rankings (do they rank for "SEO agency" + their location?), ask for case studies with real data, look at their Google reviews, and insist on a clear monthly report structure before signing. Legitimate agencies welcome scrutiny.

How much should I pay for SEO services?

In the UK, professional SEO services typically cost £500-£2,000/month for local businesses. Anything under £300/month is unlikely to deliver meaningful results. The right investment depends on your market competition and revenue potential.

How quickly will I see results from SEO?

Local SEO improvements can appear within 4-8 weeks for less competitive keywords. More competitive terms typically take 3-6 months. Any agency claiming results in weeks for competitive keywords is likely using unsustainable tactics.

What questions should I ask an SEO agency before hiring them?

Ask: What will you do in the first 3 months? How will you report results? Do I own the content you create? Can I see case studies from similar businesses? What is your contract structure? Do you guarantee rankings (correct answer: no)?
