The official use-case list includes SEO monitoring but does not describe generative visibility or GEO readiness: https://changetower.com/uses/
LinkResearchTools

The public pricing page lists Free, $12 Lite, $36 Essential, $78 Business and custom Enterprise tiers: https://changetower.com/pricing/
LinkResearchTools
A short paid trial and multiple term options exist, but the entry subscription is expensive and enterprise pricing is custom.

Buying
How useful the tool is before payment through free tools, free plans, trials, or public utilities.

The Free column includes 3 monitored pages, daily checking, 30-day retention, AI monitoring, keyword tracking and email notifications: https://changetower.com/pricing/
LinkResearchTools
A free LRT SEO Toolbar is documented, but the core platform is paid and the official page does not establish a broad free-tool allowance.

Estimated customer scale
Market proof
Estimated customer or user scale based on public claims, with source claims stored separately for auditability.
ChangeTower
No current first-party numeric customer or user count was found on the reviewed official pages.
The homepage uses non-numeric language about leading companies and trusted solutions, without a customer-count figure: https://changetower.com/
LinkResearchTools
No auditable customer count was found; brand logos, '1000s of penalties' and experience claims do not establish a customer number.

Agent readiness level
Automation
How ready the product is to operate as or inside an AI agent workflow, based on tracked subcriteria for autonomy, controls, integrations, memory, and evaluation.

LinkResearchTools
No agentic interface, autonomous agent, tool-calling protocol or agent API workflow was found.
Reviewed official homepage, tool catalog, tour and pricing pages describe human-directed reports and actions, not agents: https://www.linkresearchtools.com/seo-tools/ and https://www.linkresearchtools.com/tour
Ease of use and autonomous level
Automation
How easy it is for a team to reach useful outcomes, and how much work the product can perform autonomously after setup.
ChangeTower
Once configured it monitors automatically, but users must select URLs, criteria and notification rules.
The documented workflow requires choosing a URL, setting custom alert criteria, and then receiving reports: https://changetower.com/
LinkResearchTools
Some semi-automation exists through automated recommendations, recurring analysis, scheduled recrawls, alerts and one-click actions, but review and decision-making remain human-led.
Benefits and tour document automated recommendations, recurring analysis, scheduled recrawls, summary emails and one-click repair/recrawl actions: https://www.linkresearchtools.com/benefits/ and https://www.linkresearchtools.com/tour
