The closest price comparison depends on the job. Foglift Launch is the lower-cost integrated improvement workflow. Ahrefs Lite supplies a much broader traditional SEO dataset and five tracked AI prompts.

The verdict

Foglift is the stronger fit for a focused AI-search operating loop. The permanent free Technical Audit gives teams a low-friction baseline. Launch then connects daily monitoring across five engines to recommendations, full-site audits, crawler-purpose analytics, recognized referrals, API, CLI, hosted MCP, webhooks, and batch scanning for $49 per month.

Ahrefs is the stronger fit for broad SEO intelligence. Its backlink and keyword databases, rank tracking, large-scale Site Audit, and search-demand-backed Brand Radar index serve teams whose AI work sits beside a mature SEO programme. Current Ahrefs plans also include API and MCP access from Lite, Bot Analytics, AI traffic reporting, and Claude custom prompts.

The clean buying rule is scope. Start with Foglift when you need to diagnose a site, monitor five answer engines, prioritize changes, and verify answer, crawler, and referral outcomes in one focused product. Choose Ahrefs when backlink, keyword, and market-index depth justify the broader suite and its higher entry price.

Method and current sources

We compare the products by entry price, monitored surfaces, audit scope, improvement workflow, traffic evidence, and developer access. We favor first-party pricing and product documentation, state where the jobs differ, and correct the page when either vendor changes a public contract.

These sources explain why the comparison separates AI-answer visibility from search rank, checks results by engine, and dates product evidence. They do not determine feature or pricing verdicts and do not establish universal ranking factors.

Aggarwal et al., “GEO: Generative Engine Optimization,” KDD 2024.

The study did not test JSON-LD or Google AI Overviews.
SE Ranking, “What actually drives AI citations,” current first-party study summary. The analysis covers 129,000 domains and 216,000 pages for ChatGPT plus 295,000 domains and 2.3 million pages for AI Mode. Referring domains ranked first for ChatGPT; organic traffic ranked first for AI Mode.
Chatoptic, “SEO ≠ GEO: Only 62% Overlap Between Google Ranking and ChatGPT Visibility,” 2025. Across 1,000 queries, 15 brands, and five categories, Google top-10 position had a 0.034 correlation with ChatGPT mention order when browsing was on. The study measured mentions and order, not URL citations.
Ahrefs, “AI Assistants Prefer to Cite Fresher Content,” 2025. Across 16.975 million cited URLs, AI-assistant citations skewed newer than organic results on average, while Google AI Overviews did not. Treat recency as an observational signal, not a causal score.
