Why us

Why AEOscore comes out ahead

AEOscore comes out ahead because you can start at £99 a month, software-only, with no minimum term, and every plan tracks all six engines, Claude included.

  1. 01

    £99 a month to start, software-only, month to month

    Monitor is £99 a month, software-only and month to month: it tracks all six engines every week and writes the fix plans, briefs and full drafts for you to ship, with no minimum term. Rank4AI's lowest published price is £800 a month with a "3-month minimum, ideally 6"; Tilio's Fractional Specialist starts at £1,450 a month with a three month minimum, and Gain is quoted to your scope.

  2. 02

    Changes made at a published price, with more included

    Monitor + Strategist is £1,495 a month, month to month, and the price includes a strategist and developer day every month: the changes made on your site, new pages included, publishing through your CMS or as pull requests, posts on your channels and outreach sent for you, with daily scans across all six engines. Tilio lists "Publishing in your CMS" under "What costs extra" on its pricing page, and quotes Gain to your scope.

  3. 03

    Claude on every plan

    All six engines, Claude included, are tracked on every plan, so Claude is in your numbers from the first scan. Tilio says every programme "starts with ChatGPT, Google Gemini and Google AI Overviews", and that "Additional supported engines, including Anthropic Claude, Perplexity, Microsoft Copilot and Google AI Mode, are agreed in your scope."

  4. 04

    Daily tracking on Monitor + Strategist

    Monitor + Strategist scans all six engines every day, so a move shows the day it happens; Monitor scans weekly. Rank4AI's methodology page answers "How often is your data refreshed?" with "Citation tests run weekly", and its pricing page lists "Weekly AI testing" on its Partner tier, from £5,000 a month, and "Monthly AI testing" on Strategic.

  5. 05

    Score weights published

    Our methodology page publishes the whole score formula, so you can check any number we report: 40% Visibility, 15% Share of voice, 15% Citation, 10% Prominence and 20% Reputation. Rank4AI's methodology page describes "A weighted score reflecting the relative importance of each signal layer for your specific business category"; the weights are not stated on the pages we checked.

  6. 06

    A named strategist who is also a full-stack developer, backed by Goreblimey's in-house developers

    Olly, one named expert who leads the work, is an AEO consultant and full-stack developer with more than 20 years in search, backed by Goreblimey's in-house developers. On Monitor + Strategist the person who finds a gap makes the fix, from copy and content to schema and code.

Head to head

AEOscore vs Tilio

AEOscore is the better pick if you want a published price, month to month, with Claude on every plan; Tilio suits a larger programme quoted to your scope.

Credit where due

Where Tilio and Rank4AI are stronger

AEOscore does not track Copilot yet, which Tilio and Rank4AI can both cover, and Rank4AI's off-site work is wider, across "85+ platforms and sources".

Tilio

  • Microsoft Copilot can be added by scope; Copilot tracking is coming soon to AEOscore.

Rank4AI

  • Off-site work across "85+ platforms and sources".
  • Copilot is one of the six platforms its method tests; Copilot tracking is coming soon to AEOscore.

Where we fall short

  • We do not track Copilot yet (it is coming soon) or Grok. Tilio adds Copilot by scope, and Rank4AI tests it in its method.
  • We have no published client case studies yet: the results we publish are our own site's score. Tilio's published result is also its own brand.

FAQ

AEOscore, Tilio and Rank4AI: common questions

AEOscore tracks Claude on every plan with no minimum term; Tilio and Rank4AI can track Claude too, with three month minimums on Tilio's Fractional and Rank4AI's retainers.

AEOscore vs Tilio: which should I choose?
AEOscore, if you want the changes made at a published price, month to month, with Claude tracked on every plan: Monitor + Strategist is £1,495 a month with no minimum term, or Monitor is £99 a month, software-only. Tilio suits a larger scoped programme: Gain is quoted to your scope, and Fractional starts at £1,450 a month with a three month minimum. Tilio starts every programme with ChatGPT, Google Gemini and Google AI Overviews and agrees Claude in your scope.
What is a good Tilio alternative in the UK?
AEOscore is a UK alternative to Tilio with both prices published: Monitor at £99 a month, software-only, or Monitor + Strategist at £1,495 a month, where we make the changes on your site. Both are month to month and track all six engines, Claude included. Rank4AI is another UK AI search specialist, with Ecosystem work from £800 a month and site work from £1,500 a month, on a 3-month minimum.
Is Tilio an agency or a software company?
Both, under one company. Tilio is the AEO agency and Answyn is the software platform, and both are trading names of Luto Ventures Ltd, company number 16563350. Answyn's About page says: "Tilio is the agency. Answyn is the software." Answyn's own site lists Gemini and ChatGPT on its Pro plan, adds Google AI Overviews and Google AI Mode on Business, and can cover Claude, Perplexity and Microsoft Copilot on Custom plans.
Does Rank4AI make changes to my site?
Not on its Ecosystem work. Its pricing page describes the entry option, from £800 a month, as "Ecosystem only. No site work." Yes on Full Agency, which "Includes Site Work", from £1,500 a month. Its Advisory service is "We advise, you implement". Every engagement "starts with a free audit", and retainers carry a "3-month minimum, ideally 6".
Which of them track Claude?
All three can. AEOscore tracks Claude on every plan, from Monitor at £99 a month, software-only. Tilio starts every programme with ChatGPT, Google Gemini and Google AI Overviews, and Claude, Perplexity, Microsoft Copilot and Google AI Mode are "agreed in your scope"; Answyn, its platform, can cover Claude on Custom plans. Rank4AI's method tests six platforms including Claude and Copilot, and its pricing page lists "All six AI platforms covered" on its £1,300 Core Ecosystem tier.
Is there a minimum term?
Not with AEOscore: both plans are monthly, cancel anytime, with no minimum term. Tilio's Fractional service is "Three months minimum, then rolling", and Gain's commitment is set out in its written proposal. Rank4AI's monthly retainers carry a "3-month minimum, ideally 6".
Which is cheapest to start?
AEOscore Monitor, at £99 a month, software-only, with no minimum term: it tracks all six engines every week and writes the fix plans and full drafts you ship. Rank4AI's lowest published price is £800 a month on a 3-month minimum, Tilio's Fractional starts at £1,450 a month, and Tilio quotes Gain to your scope. All three offer a free starting point: our free six-page AI visibility report, checked by a person across all six engines, Rank4AI's free audit and Tilio's free AI checker.
Do any of them guarantee results?
No. Tilio answers "Can an AEO agency guarantee AI recommendations?" with "No." Rank4AI's terms say "We do not guarantee rankings, visibility, traffic, or commercial outcomes." Our terms say we cannot guarantee that any engine will mention or recommend your business, because the engines are third-party services that change without notice.

What changed on this page

  • : Checked the AEOscore column against our own pricing, about and free report pages and corrected it: reporting on both plans, everything each plan includes, the free six-page report, who does the work and the company line. Trimmed the rival strengths to what they offer that we do not yet: Copilot, and wider off-site work.
