Impossible Marketing sells SEO from S$1,099 a month and AI SEO inside EDGE packages, Heroes of Digital runs SEO and GEO on a 12-month roadmap with lead-based reporting, and Aemorph runs SEO, AEO and GEO as one programme for established and enterprise brands. All three work on AI search; they differ in price point, in what they report and in what they promise. This page compares the three on scope, AI search, guarantees, prices, EDGE packages and reporting, as each publishes them as of October 2026.
Aemorph, Impossible Marketing and Heroes of Digital at a Glance

How Do Their SEO Methods Differ?
Impossible Marketing, Heroes of Digital and Aemorph all cover technical SEO, content and authority building, and the differences sit in who implements the fixes, how content volume is set and where AI search work begins. Each subsection below puts the agencies side by side on one part of the work.
Technical SEO and site architecture
Impossible Marketing lists a website audit, technical SEO, off-page SEO and link building, local SEO and conversion rate optimisation among ten core SEO services. It names Ahrefs, SEMrush, Screaming Frog, Sitebulb and Google Search Console among its tools.
Heroes of Digital lists technical SEO, on-page SEO, SEO audits and conversion optimisation in its SEO scope, with ecommerce and enterprise SEO as separate lines. Landing pages and conversion work sit in the same agency as the search work.
Aemorph audits the technical base of your site and writes the fix specifications, then your developers or IT vendor implement them and Aemorph checks the result. The technical SEO audit runs within 21 days of kick-off and covers crawling, indexing, canonical tags, redirects, site architecture, speed, mobile usability, JavaScript rendering, structured data and AI crawler access. Aemorph does not edit your CMS, so fixes move at the pace of your own team.
Content, keywords and topic coverage
Impossible Marketing's EDGE listing fixes the volume package by package: Packages 1 to 3 pair AI SEO with Google Ads, social ads or social media management and cover up to 60 keywords and 60 AI prompts with 12 blog articles over 3 months, at S$10,000. Package 5 pairs AI SEO with content marketing over 5 months, with the same 60 keywords and 60 prompts, 20 blog articles and one premium media article, at S$10,350; every AI SEO package targets at least 10% of keywords in Google's top 10 and at least 10% prompt visibility.
Heroes of Digital runs SEO on a 12-month roadmap in three phases: Foundation in months 1 to 3, Authority and Expansion in months 4 to 6, and Domination in months 7 to 12. Keyword research, SEO content strategy and authority building sit inside that roadmap.
Aemorph plans content around topics and the questions your buyers ask, with no keyword cap, and quotes a monthly package on the number of pages it produces. Focus topics and keywords are agreed with you, and keywords keep each page tied to what buyers type into Google. Competitor analysis runs at the start of the campaign and again every quarter, and first ranking movements show within 45 days of publishing, as clients describe in the client videos.
AI search: AEO and GEO
Impossible Marketing's AI SEO audits your visibility across AI platforms, then builds thought-leadership articles, Q&A content, digital PR and brand mentions, and tracks mentions, citation frequency and sentiment. It names ChatGPT, Gemini, Google AI Overviews, Perplexity and Claude, and runs the tracking on its own ImpossiblePlus tool.
Heroes of Digital builds AI SEO and GEO from entity positioning, citable content blocks, schema markup and third-party mentions, and states that no agency guarantees inclusion in AI-generated answers. Its stated aim is a business that AI systems find easier to understand and summarise.
Aemorph starts AI search work from your showstopper questions, the buyer questions that stop a purchase when AI answers them badly, and your approved answers go live as the LLM info page on your own site. The Showstopper Sensor (Sprint 1) delivers that work within 30 days; inside the Attain and Apex engagements the same work runs over 12 months alongside SEO. GEO covers ChatGPT, Claude, Gemini and Perplexity, and AEO covers Google AI Overviews, featured snippets and voice answers.
Local and regional reach
Impossible Marketing lists local SEO among its ten core SEO services and serves Singapore businesses from its Singapore base. Its EDGE listing pairs AI SEO with Google Ads, social ads or social media management.
Heroes of Digital runs a team across Singapore, Malaysia and the Philippines, with Singapore and Malaysia market pages, and lists healthcare, legal, education, home services, professional services and B2B as its industries. Local SEO sits in its SEO scope.
Aemorph serves Singapore businesses from its Singapore headquarters and writes content in Thai, Vietnamese, Indonesian and Chinese on top of English, each language priced separately. Local SEO suits organisations with three or more locations, and international SEO covers a brand selling in several markets.

How Does Each Agency Report Results?
Each agency reports on a different measure, and the report you sign up for decides what you hold the agency to each month. Impossible Marketing assigns a client success manager who monitors performance weekly and sends monthly reports from the second month, with AI SEO reports covering visibility trends, brand mentions and citation growth. Heroes of Digital reports qualified leads, cost per qualified lead, lead-to-sale conversions and booked calls through its HeroIQ platform. Aemorph sends a monthly report that groups results by topic and prompt cluster, with ranking reports alongside, and every engagement has its own account manager who replies within 24 hours. Aemorph tracks rankings, traffic and AI visibility because those are the results its work controls, and it does not collect your sales or enquiry figures.
What Aemorph's SEO Has Delivered for a Client
Aemorph records SEO results as organic traffic estimated by Ahrefs, the same measure on every Aemorph case study. The result below is organic search growth from SEO; it is not an AI citation result.
