Questions for a London SEO agency
Start with the constraint holding the site back, then compare diagnosis, implementation and measurement.
A meeting guide for comparing SEO proposals in London.
Criterion
What to ask
What a useful answer covers
Primary SEO constraint
What to ask Is the priority technical repair, migration, local search, ecommerce or content?
What a useful answer covers A diagnosis tied to site history and commercial priorities, with observations separated from hypotheses.
Shared baseline
What to ask What access and context do you need before proposing work?
What a useful answer covers Controlled access to Search Console, analytics, crawl information, platform details and past migrations.
First 90 days
What to ask What will you tackle first, and what depends on our team?
What a useful answer covers A phased plan naming owners, access needs, acceptance criteria and deferred work; no fixed promise of results.
Implementation
What to ask Who writes specifications, changes the site and checks releases?
What a useful answer covers A clear split between consultancy, development, content and quality checks, with changes logged.
Migration controls
What to ask How will you protect search visibility during a platform change?
What a useful answer covers URL mapping, redirects, canonicals, internal links, sitemaps and checks before and after launch.
Account and asset ownership
What to ask How do you govern links, content rights and access?
What a useful answer covers Documented methods, licensing responsibilities, client account ownership and a workable handover.
Delivery team
What to ask Who will do the work and make decisions?
What a useful answer covers Named day-to-day and senior contacts, clear responsibilities, subcontractor arrangements and escalation routes.
Measurement
What to ask How will we judge progress?
What a useful answer covers An agreed baseline, business-relevant measures, reporting frequency and an explanation of attribution limits.
Commercial scope
What to ask What is included in the proposal?
What a useful answer covers Itemised deliverables, assumptions, third-party costs, exclusions and a process for agreeing changes.
Measure organic demand that matters
Connect landing-page traffic and technical health to qualified enquiries or ecommerce revenue. Agree how brand and non-brand demand, assisted conversions and site releases will be reported. Keep experimental AI-search measures separate from conventional organic search.
Working with a London team
Decide whether workshops, stakeholder access or local-search context make a London office useful. Confirm where the people delivering the work are based and whether developers and content owners can join key decisions.
Fit the contract to implementation
An audit can suit a team ready to implement recommendations. For a rebuild, write SEO acceptance criteria into design, development and release responsibilities. Compare milestones and dependencies before agreeing an ongoing fee.
How these providers were selected
Eligibility requires a provider role, an explicit London office in the UK and a direct SEO service classification. Related service categories alone do not qualify. The order reflects the amount and relevance of information available to compare, the specificity of feedback and a clear match to the named provider. It does not rank service quality or predict results.
01
City and service fit
The shortlist draws on 22 eligible providers with a London office and the required service classification. Confirm the actual delivery location and team before appointment.
02
One focal point per card
Each card highlights one Google review, one Google aggregate or a case study with an established agency role. Review statements remain the reviewer’s account, and ratings describe feedback on Google.
03
Relevant detail before broad claims
Specific accounts of delivery and clearly attributed work help buyers form questions. The sequence also considers whether feedback refers to the correct agency and whether it addresses the service being compared.
04
Buyer checks remain essential
Meet the team and discuss current capability, responsibilities, references, reporting and commercial terms against the same brief.
Define the site problem, commercial objective, baseline and implementation constraints. Give each provider the same brief and ask who will diagnose, implement and check the work.
How much does SEO cost in London?
Pricing information is unavailable for these providers. Scope depends on site size and condition, competition, technical changes, content, digital PR, seniority and who implements recommendations. Request an itemised proposal with assumptions and exclusions.
How long does SEO take to work?
There is no universal timetable. Observable changes depend on site condition, crawling and indexation, competition, content and implementation speed. Ask for milestones, assumptions and review points.
What should an SEO agency report?
Reports should connect completed work and technical health to search visibility, qualified organic enquiries and agreed business outcomes. Request access to the underlying analytics, clear definitions and annotations for site changes.
What is the difference between local SEO and technical SEO?
Local SEO addresses location-relevant discovery, business profiles and local pages. Technical SEO concerns how a site is crawled, rendered, indexed and understood. Diagnosis should determine whether you need either or both.
Can an SEO agency guarantee first-place rankings?
No provider controls search-engine rankings. Ask for transparent assumptions, prioritised work, implementation checks and measurable milestones instead of guaranteed positions.
Do I need an SEO agency with a London office?
A London office may help with workshops, stakeholders and local-market context. Confirm where the delivery team works and weigh in-person access alongside specialism, communication and implementation fit.
How should I assess AI-search proposals?
Ask which activities differ from conventional SEO, what systems will be measured and how visibility will be tracked. Agree what is experimental and how any commercial effect would be assessed.
How can Sortlist help me compare providers?
Use Sortlist to explore provider profiles, compare information, build a shortlist or submit a project brief. Follow up with your own capability, reference and commercial checks before appointing a partner.
