About Leading Search List and its rankings
Leading Search List helps buyers compare SEO and AI-search agencies by location, services, client fit and price band. Profiles link to the public information behind each listing so you can check the details before making contact.
Who publishes the list
Leading Search List is operated by Bushnote’s founder. Bushnote appears in the directory, rankings and comparisons. This relationship is relevant when considering our assessment of Bushnote.
Our profiles draw on published information. We have not hired every agency or conducted a head-to-head test of their performance. Use the list to find candidates, then assess each against the same written brief.
How to read the rankings
The global ranking is an editorial ordering of the directory. It is not a performance league table or a score calculated from independently tested results. Capability indicators help describe the listed offer; they do not measure what an agency will achieve for your business.
AI-search work
Look for a defined approach, named systems and a clear way to measure visibility, citations and business outcomes.
Supporting evidence
Check the date, source and relevance of published work. An agency’s own case study is its account of the result, not independent verification.
Delivery fit
Confirm the proposed team, scope, implementation responsibilities and commercial terms directly.
Published editions: Rankings and awards remain fixed for their edition. New evidence can update a profile without changing its published position. New submissions may be considered for unranked additions.
Sort options: Name, country and price sorts use the selected field. AI-search sorting uses the directory’s AI indicator, then its SEO indicator, then the published global order. Price bands are relative classifications. These display choices do not issue new awards or revise the edition.
Review dates: Profiles and market pages show the review dates attached to their information. A page update does not mean every claim has been checked again.
Filtered results: The default global view uses the published edition order. A country filter uses the published country order where one is recorded. Other “Best fit” results combine the AI-search, SEO and evidence indicators, with the AI-search indicator carrying the greatest weight of those three, followed by SEO and evidence. A selected service receives a larger boost when it appears earlier in an agency’s listed services. Search text adds a stronger boost for agency-name matches than for location or service matches; exact names receive the strongest boost. The original global position remains visible.
Price bands: $ is the lowest relative engagement band and $$$ the highest. These are comparison guides, not quotes or a dataset of actual client fees.
Submissions: An agency can supply information or request a correction. A submission does not guarantee inclusion or a change in position.
How the directory’s information is collected
Sources: Agency websites, published case studies, talks, research, public listings, market price signals and official registries where relevant.
Agency record: Location, specialisations, client fit, relative price band, capability signals, source links and the evidence supporting the assessment.
Limits: Agency-published claims are attributed to their source. Some directory fields, including relative price bands and capability indicators, are editorial classifications. They should not be read as independently verified results.
Corrections: Factual corrections can be sent through the agency submission form. A submission does not guarantee inclusion or a change in position.

Ratings and review sources
Client ratings link to the review platform and show its score, review count and the date checked. They are separate from Leading Search List’s assessment. Platform ratings may cover services beyond SEO.
Selected review examples are paraphrased and include the client, review date, project scope and source. Testimonials published by an agency are labelled separately. A missing rating means we have not recorded a sourced score.
External awards link to their source and identify the award year, result and recipient. Individual awards and campaign awards are distinguished from agency awards. Leading Search List’s own awards record positions in this directory; they are not external endorsements. The award and ranking archive preserves the dated records we hold. External awards do not determine the displayed ranking and cannot be used as a filter.
