The SEO industry has a due diligence problem. Unlike accountancy or law, there is no professional body, no regulated qualification, and no standard of care that every provider must meet. Anyone can call themselves an SEO consultant. The result is a market where genuine specialists — who build semantic content networks, apply named methodologies, and deliver measurable organic growth — compete for the same budget as generalists who learned SEO from a YouTube course and charge the same monthly retainer.
The ten warning signs below are drawn from direct experience — from auditing the work of previous providers when businesses come to us after a disappointing engagement. They are specific, verifiable, and actionable. You can check every one of them before you sign.
The 10 Warning Signs
They guarantee a first-page ranking
CriticalNo SEO provider can guarantee a specific ranking position. Google's algorithm is not a vending machine. Any consultant or agency that guarantees 'first page in 90 days' is either lying or planning to use tactics that will damage your site long-term. A credible provider will give you realistic projections based on your domain authority, competitive landscape, and content gap — not a guarantee designed to win the sale.
They can't explain their methodology
CriticalAsk any SEO provider: 'What is your methodology?' A specialist will explain a named framework — semantic content networks, topical authority building, entity-attribute-value scope, structured internal linking. A generalist will describe a process: 'We audit your site, fix technical issues, build links, and publish content.' The process description is not a methodology. It is a list of tasks. If they cannot explain why their approach works — the mechanism, not just the steps — they are following a template, not a strategy.
You will never speak to the person doing the work
HighAt the pitch, you meet a senior consultant or agency director. After you sign, your account is handed to a junior account manager who relays messages to a junior SEO executive. This is the standard agency model, and it is not inherently wrong — but you should know it is happening. Ask directly: 'Who will I communicate with after I sign? Is it you, or an account manager?' If the answer is vague, or if the account manager is introduced as 'your main point of contact,' you have your answer.
Their reporting is traffic-only
HighTraffic is a vanity metric. A provider who reports only on sessions and impressions is hiding the absence of a real strategy. Meaningful SEO reporting includes: which specific queries you are now ranking for and why; how your topical coverage has expanded; which pages are driving qualified leads or revenue; what the content architecture looks like now versus three months ago. If your monthly report is a Google Analytics screenshot with a green arrow, you are not receiving strategic SEO — you are receiving the appearance of it.
They publish content without a topical map
HighPublishing blog posts without a topical map is the single most common waste of SEO budget. Without a semantic content network — a documented architecture of which pages cover which entities, attributes, and values, and how they link to each other — you are creating content that competes with itself, dilutes your topical authority, and fails to build the cost-of-retrieval signal that Google rewards. Ask to see the content architecture. If there is no document, there is no strategy.
They use the word 'backlinks' as a primary strategy
MediumLink building is not dead, but it is not the primary lever for most London SMEs in 2026. A provider whose strategy centres on 'building backlinks' without a corresponding content architecture is working from a 2015 playbook. Links matter — but topically aligned links to a semantically structured site matter far more than volume link building to a site with no content architecture. Ask what percentage of their effort goes to content architecture versus link acquisition. If the answer is more than 50% links, ask why.
They can't tell you what they won't do
MediumA specialist knows their scope. A generalist claims to do everything. Ask any SEO provider: 'What falls outside your scope? What would you refer out?' A credible answer might be: 'I don't run large-scale link outreach campaigns — I use digital PR and topical link building instead' or 'I don't do paid search — that's a different discipline.' A provider who claims to do everything — SEO, PPC, social, PR, web design, content — is doing none of them well.
Their contract has a 12-month lock-in with no performance clause
MediumA 12-month contract is not inherently wrong — SEO takes time and a provider needs runway to deliver results. But a 12-month contract with no performance clause and no exit mechanism is a red flag. Ask: 'What happens if we are not seeing meaningful progress at month six?' A confident provider will define what meaningful progress looks like and agree to a review point. A provider who refuses to define success metrics before you sign is protecting themselves, not you.
They use AI to write all your content without disclosure
MediumAI-generated content is not inherently bad. AI-generated content published without human expert review, without entity coverage checks, and without EAV scope discipline is actively harmful to your topical authority. Ask any provider: 'How do you use AI in your content process?' A credible answer describes AI as a tool for research, clustering, and brief generation — with human expert review applied before publication. An answer that describes AI as the primary content writer, with no mention of quality control, is a warning sign.
They can't show you work from a comparable client
AdvisoryCase studies are easy to fabricate. Ask for a reference call with a client in a comparable industry and market. Ask to see the actual content architecture — a topical map, a content brief, a technical audit — not just a traffic graph. A provider who cannot or will not show you the work product, only the results, is asking you to trust a black box. The mechanism matters as much as the outcome.

From Our Work
What we find when we audit previous agency work
The most consistent pattern when auditing a site after a previous agency is a site that has been treated like a content machine rather than a structured search asset. The agency may have been producing work — publishing posts, building links, sending monthly reports — but not building a system that actually compounds.
In practice, this shows up as thin content across dozens of pages, index bloat from uncrawled filter and variant URLs, weak internal linking with no clear hierarchy, and no topical architecture connecting the content to the site’s commercial pages. Pages were targeting overlapping keyword clusters, creating internal competition rather than reinforcing each other.
The client was shown traffic graphs and keyword ranking tables each month. The content architecture — the actual strategic work that would have made those pages compound — had either not been built or had not been communicated. In every case, the client did not know what they had not been given.
The distinction matters: producing content is not the same as building a search asset. A structured search asset has a topical map, defined EAV scope per page, deliberate internal linking, and a clear pathway from informational content to conversion pages. A content machine just publishes.

What Good Looks Like: The Due Diligence Checklist
Before you sign any SEO contract, run through this checklist. Every item is a direct question you can ask at the proposal stage. A credible provider will answer all of them without hesitation.
Can you explain your methodology — not your process, your methodology?
Look for a named framework with a rationale, not a list of tasks.
Can you show me a topical map or content architecture you built for a comparable client?
A document, not a traffic graph.
Who will I communicate with after I sign? Is it you, or an account manager?
The answer should be unambiguous.
What does the first 90 days look like in concrete deliverables?
Specific outputs: audit, topical map, content briefs, technical fixes.
What do you not do? What would you refer out?
A specialist knows their scope.
What does success look like at 6 months, and how will we measure it?
Defined metrics, not just 'improved rankings'.
What happens if we are not seeing meaningful progress at month six?
Look for a defined review process, not a deflection.
Can I speak to a current client in a comparable industry?
A reference call, not a written testimonial.
What is included in the monthly retainer, line by line?
Specific deliverables, not 'ongoing SEO work'.
How do you use AI in your workflow, and how do you quality-control the output?
AI as a tool, not as the primary content writer.

The Contract: What to Demand Before You Sign
A well-structured SEO contract protects both parties. It defines what success looks like, what the provider will deliver, and what happens if the engagement is not working. A contract that lacks these elements is protecting the provider, not you.
The minimum a credible SEO contract should include: a defined scope of work with specific monthly deliverables; a statement of what is not included; success metrics agreed before the engagement starts; a review clause at 3–6 months; an exit mechanism (typically 30–60 days notice after an initial period); and a clear statement of who owns the content, data, and assets produced. If any of these elements are missing, ask why before you sign.
On pricing: a credible provider should be able to tell you, before you sign, exactly what you receive for your monthly fee. For a transparent view of what different SEO retainer tiers include and what questions to ask at each price point, see our pricing page.
Frequently Asked Questions
How do I check if an SEO agency is legitimate?+
Ask for three things: (1) a reference call with a current client in a comparable industry; (2) an example of a topical map or content architecture they built; (3) a clear explanation of their methodology — not a process list, but a named framework with a rationale. A legitimate provider will provide all three without hesitation. Also check their own website's SEO — if an SEO agency's own site has no topical architecture, thin content, and no internal linking strategy, that tells you everything.
Is it a red flag if an SEO agency doesn't show pricing on their website?+
It is a yellow flag, not a red one. Some legitimate providers don't publish pricing because their engagements are genuinely scoped to client requirements. But opacity about pricing at the proposal stage — vague retainer descriptions, no deliverable breakdown, resistance to defining what's included — is a red flag. A credible provider should be able to tell you, before you sign, exactly what you get for your monthly fee.
What should a legitimate SEO contract include?+
At minimum: a defined scope of work with specific deliverables per month; a clear statement of what is not included; a review clause at 3–6 months with defined success metrics; an exit clause (typically 30–60 days notice after an initial period); and a clear statement of who owns the content and assets produced. Anything that lacks deliverable specificity or success metrics is protecting the provider, not you.
How quickly should I expect to see SEO results?+
For a new or low-authority domain, meaningful ranking movement typically takes 4–6 months. For an established domain with existing authority, you may see movement in 6–12 weeks for targeted pages. Any provider who promises results in less than 4 weeks is either targeting very low-competition queries (which may not drive meaningful traffic) or using tactics that risk a Google penalty. The honest answer is: it depends on your starting point, your competitive landscape, and the quality of the strategy.
Is it safe to hire a freelance SEO consultant I found on LinkedIn?+
LinkedIn is a legitimate sourcing channel, but it requires the same due diligence as any other channel. Ask for methodology, references, and work examples. Check their own LinkedIn profile's SEO — do they practice what they preach? A freelancer who can articulate a named methodology, show a topical map they built, and provide a reference call is a credible candidate regardless of where you found them.
What is the difference between a technical SEO issue and a content strategy issue?+
Technical SEO issues prevent your pages from being crawled, indexed, or rendered correctly — broken links, slow Core Web Vitals, missing schema, duplicate content, poor site architecture. Content strategy issues prevent your pages from being relevant to the right queries — missing topical coverage, poor EAV scope, no internal linking architecture, content that competes with itself. Most sites that aren't ranking have both. A credible audit will distinguish between them and prioritise accordingly.
