You invested in SEO for sustainable, long-term growth. You signed the contract, set the budget, and waited patiently. Months later, the needle hasn’t moved—or worse, traffic is declining and leads have dried up. Before you blame SEO itself, look at who’s executing it. This is your definitive checklist for identifying an underperforming agency.
Choosing an SEO agency in London is one of the highest-leverage decisions a business can make. The right partner compounds your visibility, authority, and revenue quarter after quarter. The wrong one burns budget, wastes months of momentum, and can even damage your domain with reckless tactics.
We’ve audited dozens of businesses that came to us after being let down by previous agencies. The patterns are strikingly consistent. Here are the seven red flags that tell you it’s time for a serious conversation—or a clean break.
Lack of Transparency in Reporting
- You don't have direct access to Google Analytics or Google Search Console—your agency controls everything.
- Monthly reports are stuffed with jargon, vanity metrics, and charts that look impressive but offer no actionable insight.
- You can't see a clear log of what work has actually been done each month—no task lists, no deliverables breakdown.
- Metrics are cherry-picked to paint a positive picture while ignoring declining areas.
- Questions about strategy or performance are met with vague reassurances rather than data.
What to Demand Instead
- ✓Full, direct access to GA4 and Google Search Console—your properties, your data.
- ✓Monthly reports with clear KPIs tied to business outcomes: leads, revenue, rankings for target terms.
- ✓A documented work log showing exactly what was delivered, when, and why.
- ✓Standing monthly calls with screen-share walkthroughs of performance data.
Stagnant Keyword Rankings
- Your target keywords haven't moved meaningfully in 6+ months despite ongoing spend.
- There's no documented keyword strategy mapping terms to pages and business objectives.
- No local keyword strategy targeting London-specific or geo-modified terms for your market.
- You can't name your top 20 target keywords or explain why they were chosen.
What to Demand Instead
- ✓A documented keyword strategy with clear rationale for every target term.
- ✓Monthly ranking reports showing movement, trends, and SERP feature opportunities.
- ✓A local SEO keyword plan if you serve London or specific geographic markets.
- ✓Quarterly strategy reviews to adjust targets based on performance and market shifts.
Outdated Link Building Tactics
- You have no visibility into your backlink profile—you've never seen a link report.
- Links are coming from low-quality directories, spammy guest post farms, or private blog networks (PBNs).
- Your anchor text profile is unnaturally concentrated on exact-match commercial keywords.
- You're at risk of a Google manual action or algorithmic penalty from toxic links.
- The agency can't explain their link building methodology when asked directly.
What to Demand Instead
- ✓Full transparency on every link acquired—source, domain authority, relevance, and anchor text.
- ✓A quality-focused link building strategy centred on digital PR, expert commentary, and genuine editorial placements.
- ✓Regular backlink audits with toxic link identification and disavow recommendations.
- ✓A natural, diversified anchor text strategy that mirrors organic link patterns.
No Technical SEO Audits
- You've never received a comprehensive technical SEO audit of your website.
- Core Web Vitals are failing and nobody's mentioned it—pages are slow, layout shifts are constant.
- Indexation problems persist: important pages aren't indexed, thin pages are bloating the index.
- There's no ongoing technical monitoring—issues are discovered months late, or not at all.
- Site architecture, internal linking, and crawl efficiency have never been reviewed.
What to Demand Instead
- ✓An initial comprehensive technical audit within the first 30 days of engagement.
- ✓Monthly technical monitoring covering Core Web Vitals, crawl errors, indexation, and site health.
- ✓Quarterly deep-dive technical reviews with prioritised recommendations.
- ✓Proactive alerts when critical technical issues arise—not discovery during annual reviews.
Generic, Low-Quality Content
- Blog posts are under 500 words, surface-level, and read like they were written by someone with no expertise.
- Content topics are disconnected from your core services—filler posts with no strategic purpose.
- There's no documented content calendar or content strategy tying output to business goals.
- Published content isn't ranking for anything, isn't driving traffic, and isn't generating leads.
- Content lacks original data, expert insights, or any differentiation from competitors.
What to Demand Instead
- ✓A documented content strategy aligned with your keyword targets and business objectives.
- ✓High-quality, long-form content (1,500+ words) with original insights and expert commentary.
- ✓A content calendar planned at least one quarter in advance with clear rationale for each piece.
- ✓Content performance tracking: rankings achieved, traffic driven, and conversions generated per piece.
No Focus on Conversions
- Reports only show traffic and rankings—never conversions, leads, or revenue impact.
- Google Analytics conversion tracking isn't properly configured. Events, goals, and attribution are missing.
- Landing pages aren't optimised for conversion—no clear CTAs, poor UX, slow load times.
- The agency treats SEO as a traffic game, not a revenue channel.
What to Demand Instead
- ✓Properly configured GA4 event tracking, conversion goals, and attribution modelling from day one.
- ✓Monthly reporting that connects SEO activity to leads, enquiries, and revenue—not just impressions.
- ✓CRO recommendations for key landing pages: layout, CTAs, page speed, and user journey.
- ✓A shared understanding that traffic without conversion is vanity—revenue is the metric that matters.
They Never Say “No”
- The agency agrees with every idea you propose without analysis, data, or professional pushback.
- They're entirely reactive—waiting for your instructions rather than leading strategy proactively.
- There's no strategic roadmap. Each month feels disconnected from the last.
- You suspect they're a "yes-agency" optimising for client retention, not client results.
What to Demand Instead
- ✓A strategic partner who challenges your assumptions with data and experience.
- ✓A proactive quarterly roadmap with clear milestones, deliverables, and success criteria.
- ✓Regular strategic recommendations initiated by the agency—not just responses to your requests.
- ✓Honest, direct communication even when the news is uncomfortable. Your growth depends on truth, not flattery.
