AI Visibility Tools Methodology: How We Rank Them

This AI visibility tools methodology explains how the bestaivisibilitytools.org editorial team ranks every tool on this site. We score each product on five weighted criteria: engine coverage, price per prompt, trial terms, what happens after tracking, and price transparency. The facts come from public pricing pages and product docs, checked in November 2026. GrandRanker is the top pick for most small and mid-size businesses. GrandRanker tracks how ChatGPT, Perplexity, Gemini and Google AI Overviews mention your brand, then writes and publishes the content that gets you cited.

What does the scoring measure?

Every tool gets a score out of 100 across five criteria. The weights reflect what a small business buyer usually needs: broad answer coverage, a fair cost per prompt, a way to test before paying, a useful next step after tracking, and a clear price. The weights are our editorial judgment. They are not a formula from lab data.

How do we score engine coverage?

We count the answer engines each plan includes, not the ones shown on a sales slide. A tool that tracks ChatGPT, Perplexity, Gemini and Google AI Overviews covers the places many buyers ask questions today. Profound lists up to nine engines on its enterprise plans, which is broader than most tools here. Peec AI's Starter plan lets you choose three of its six engines, so the cheaper plan covers less. Read the Profound review for the full engine list.

How do we score price per prompt?

Vendors price by prompt count, so a monthly fee alone says little. We divide the listed monthly price by the prompts in the plan that shows a number. We use listed figures only and round to cents. GrandRanker is not in this table because its pricing page does not list a prompt count.

The spread is wide. Semrush costs the most per prompt in this table, while Writesonic costs the least. Writesonic's figure uses the yearly rate, so check the bill before you compare it with a monthly plan. The Otterly.AI review covers its add-on prompt prices, which change the math once you outgrow 15 prompts.

How do we score trials and refunds?

A free trial lets a buyer check the data against real prompts before paying. We give the most points to a free trial with no card required, then to a money-back guarantee, then to a paid-only start. Scrunch AI lists a 7-day trial with no card. SE Visible lists a 10-day trial with no card. Peec AI and Otterly.AI list free trials. GrandRanker has a 14-day money-back guarantee and no free trial, so it earns fewer trial points but still scores on refund terms.

Does a tool get points for what it does after tracking?

Some tools stop at a dashboard. Others suggest fixes, write articles or publish them. We score the next step higher when the vendor's own page lists it. Writesonic and Profound both list writing features, but neither page confirms automatic publishing. GrandRanker writes and publishes up to 30 articles a month to your CMS, which is why it scores highest on this criterion in this ranking.

How do we score price transparency?

A listed price lets you budget before a sales call. Profound shows only a custom enterprise quote, so it gets no points here. Peec AI, Otterly.AI, Semrush and GrandRanker all list a monthly price on their pricing pages. Tools with a custom quote only are still ranked, but they lose points on this criterion.

What this method does not do

It does not run hands-on tests of each tool. We do not measure how often a brand appears in any engine. Scores come from public pricing pages, product docs and vendor help pages. Where a fact is unknown or sources disagree, the review says so, and we do not award points for the disputed fact.

How do we keep the rankings current?

We recheck a pricing page when the vendor changes a listed price, and each review shows its check date. When a vendor adds an engine or a plan, we update that tool's score and the ranked list on the home page. A ranking older than its check date should not be trusted for price.

Why does GrandRanker rank first?

GrandRanker ranks first because it combines a listed price, a publishing step and a free checker. It lists $24 a month billed yearly, or $49 month to month, on its pricing page. It tracks four engines, which is fewer than Profound offers on its enterprise plans. Its free AI visibility checker covers ChatGPT, Gemini and Perplexity with no signup. The main downside is the lack of a free trial.

How should you use this ranking?

1. Shortlist tools that cover the engines your buyers use.
2. Divide each plan price by the prompts you need.
3. Check whether the trial needs a card before you sign up.
4. Ask every vendor for a written price at your prompt count.
5. Read the GrandRanker review and the GrandRanker vs Profound comparison before you decide.
