You receive an email from an SEO firm promising to “guarantee first page rankings in 30 days.” Red flag. You get a cold call from someone claiming their tool is “endorsed by Google.” Another red flag. You’re offered a package that costs £49 a month but requires no audit of your current website. Dodgy.

This is the trick: Google just released new guidance specifically calling out third-party SEO tools, services, and advice that don’t deliver or actively harm your site. As a North London business owner, you now have a clear checklist to evaluate whether an SEO service is legitimate or a waste of money. Let’s walk through it.

The Problem: Third-Party SEO Claims Have Gone Unchecked

Google has long been frustrated by SEO agencies, tools, and consultants making promises they can’t keep. The most common lie: “We have a special relationship with Google and can guarantee rankings.” This isn’t new, but it’s getting worse as AI and automation make it cheaper to spam businesses with hollow pitches.

In early June 2026, Google updated its official guidance on third-party SEO services. The core message is blunt: Google doesn’t endorse specific SEO tools or agencies, doesn’t guarantee results for anyone, and actively penalises tactics that violate its guidelines, regardless of who recommends them.

This matters for your business because you might be paying thousands of pounds a year to someone whose tactics could actually damage your visibility rather than improve it.

Google’s Four Key Warning Signs Your SEO Service Is Dodgy

Google’s new guidance highlights four red flags. If your SEO provider ticks any of these boxes, it’s time to look elsewhere or ask some hard questions.

1. They Claim Google Endorsement or a “Special Relationship”

No SEO tool, platform, or agency has a special relationship with Google that guarantees results. Google makes this clear: they don’t endorse third-party SEO tools, full stop. If someone says they do, they’re lying.

This includes claims like “we use Google-approved techniques” or “our tool is trusted by Google.” Google trusts nothing except following the Search Quality Evaluator Guidelines and the official Google Search Central documentation. That’s it.

What to do: Ask for specifics. If they can’t point to a published Google document backing up their claim, they’re making it up.

2. They Promise Guaranteed Rankings or Traffic Numbers

SEO is influenced by hundreds of ranking factors, algorithm updates, and competitor activity. No one can guarantee a specific position or traffic volume, no matter how confident they sound.

Phrases like “we guarantee first page rankings,” “we’ll double your traffic,” or “results guaranteed or your money back” are instant disqualifiers. Google’s algorithm changes regularly. External factors change. Competitors change. An honest SEO service says “we’ll improve your visibility through these tactics, and here’s how we’ll measure it.”

What to do: Ask how they define success. If success is a specific ranking number, move on. If success is improved CTR, more targeted visits, or better conversion rates, that’s realistic.

3. They Use or Promote Tools Without Transparency About Limitations

Google’s guidance specifically calls out third-party tools. The issue isn’t that these tools are always bad, it’s that many vendors oversell what their tool can do or don’t disclose its limitations.

A legitimate tool helps you audit your site or gather competitive data. An illegitimate tool claims to “trick Google” or “automate ranking improvements” or provides data that contradicts Google’s official metrics (like GA4 or Search Console).

What to do: If they recommend a tool, ask: (1) What does this tool actually do? (2) What can it not do? (3) How does this tool complement official Google tools like Search Console? If they dodge these questions or downplay limitations, be sceptical.

4. They Don’t Audit Your Current Situation

A shady SEO service sells the same package to everyone: the same tactics, the same timeline, the same deliverables. A legitimate service audits your site first, understands your competitive landscape, and builds a custom strategy.

If an SEO firm quotes you on a service without reviewing your site, asking about your audience, or understanding your business, they’re operating on autopilot. They’re not doing SEO, they’re doing template work.

What to do: Legitimate SEO services will spend time (usually unpaid) understanding your situation before quoting. Ask for a preliminary audit or discovery call. If they skip this step, skip them.

The Real Red Flags: Words and Phrases to Avoid

Beyond Google’s four warning signs, listen to the language. Certain phrases almost always signal a dodgy operation.

• “We rank in secrecy.” Good SEO is based on documented best practices, not secret tactics.
• “Our proprietary algorithm.” Your site ranks based on Google’s algorithm, not theirs.
• “White hat,” “grey hat,” or “black hat” without explanation. Vague ethical framing hides what they actually do.
• “Unlimited keywords.” Every keyword carries risk and effort. Unlimited means unfocused.
• “Manual submission to 500 directories.” Directory links are near-worthless and often harm visibility.
• “We’ll fix your site’s SEO in one month.” Good SEO takes 3 to 6 months to show measurable results.

What Legitimate SEO Actually Looks Like

Now you know what to avoid. Here’s what a legitimate SEO service actually does.

They start with discovery. They audit your current site, review your competitors’ tactics, research your audience’s search behaviour, and understand your business goals.

They set realistic timelines. Expect 3 to 6 months before meaningful traffic increases. Some improvements take a year or longer, depending on your industry competition.

They focus on user benefit, not just rankings. They improve your site’s speed, make it mobile-friendly, structure your content clearly, and ensure it actually answers your audience’s questions. Rankings follow good user experience, not the other way around.

They measure using multiple signals. Legitimate SEO providers track Rankings (via Search Console, not sketchy rank tracker tools), organic traffic (GA4), click-through rate (CTR), and most importantly, conversions and revenue impact.

They communicate transparently. They explain what they’re doing, why, and what results to expect. They flag algorithm updates that might affect your rankings, and they adapt strategy when needed. They’re not secretive.

They use official Google tools. Search Console, Google Analytics 4, Google’s Page Experience Insights, Lighthouse. Not proprietary dashboards that contradict Google’s own data.

Your Trick: The Five-Question Vetting Checklist

Use this simple checklist on any SEO service before you sign a contract.

1. Can you explain how you’ll improve my site without referencing guaranteed rankings or secret tactics? If they can’t, they’re selling hype.
2. What’s your process for the first 30 days? (Should be: audit, competitor research, strategy development.) Not implementation yet.
3. How do you measure success? (Should include: Search Console data, GA4 data, CTR, conversion rate, revenue impact.)
4. What tools will you use? Can you explain what each tool does and how it complements official Google tools? Watch for hand-waving or mystique.
5. Can you share case studies or examples from businesses like mine? Real examples with real numbers beat promises every time.

If they answer these clearly, transparently, and without jargon, you’ve probably found a legitimate SEO service. If they dodge, deflect, or resort to buzzwords, keep looking.

What to Do If You’ve Already Hired a Dodgy Service

If you’re currently working with an SEO firm and you’re starting to suspect they’re not legitimate, don’t panic. First, pull your Search Console data for the past 12 months. Are your impressions, clicks, and average position trending up, flat, or down? That tells you if anything’s working. Second, ask them for the five questions above. Their answers will tell you if they’re worth keeping. Third, if they can’t answer or won’t answer, request a copy of all work done to date, then move on.

A legitimate SEO service in Finchley can audit your current situation and give you a realistic roadmap. That’s where to start.

Frequently Asked Questions

Is it safe to use third-party SEO tools at all?

Yes, if the tool is transparent about what it does. Tools for site audits, keyword research, competitor analysis, or rank tracking are fine. Tools that claim to “automate” your rankings or bypass Google’s guidelines are not.

How much should a legitimate SEO service cost?

In North London, expect £500 to £3,000 per month for actual SEO work (not just reporting). Anything under £300 a month is likely template work. Anything over £5,000 should come with measurable results and transparency.

Can a small business even compete with SEO against larger competitors?

Yes. Larger competitors often do SEO poorly. Local businesses with genuine expertise, real customer reviews, clear business information, and a focus on their actual audience often outrank bigger competitors who are just chasing traffic.

What if I hire someone and they start using black hat tactics without telling me?

Terminate the contract immediately. Ask them to revert any tactics that violate Google’s guidelines. If they’ve bought backlinks or created doorway pages, Google may penalise you for a time, but recovery is possible once the bad tactics stop.

Is SEO worth it for a small business in 2026?

Yes, if done right. AI Search is fragmenting visibility, but SEO still drives qualified traffic to legitimate businesses. The catch: you need to do it honestly, with patience, and with a focus on actual user benefit, not shortcuts.
