Marvlus vs Semrush

Marvlus

Marvlus sits in the fast-growing AI-visibility-tracking category, and the free tier is enough to run one real audit before deciding if the $29/month plan is worth it. Its edge over a plain SEO tracker is watching AI-answer mentions specifically, but that also means its core promise depends on how consistently AI models actually cite anything at all for a given niche.

Pros

• +Combines AI-visibility auditing with conventional Google rank tracking in one product
• +Free tier lets you run a real homepage audit before paying
• +White-label option specifically built for agency resale

Cons

• −Paid tiers cap prompts and topics tightly (80 prompts on the $29 plan)
• −Built and apparently run by a single founder, a risk for long-term support
• −AI-visibility scoring methodology is not independently verified

Semrush

Semrush is still the broadest single subscription for anyone who needs competitor traffic estimates, keyword gaps, rank tracking and a site crawler in one login, and its 2026 plans fold AI-answer tracking into the same projects. It is priced for marketing teams and agencies: at $139 a month before extra users and add-ons, a solo site owner pays for a great deal they will never open, and the Adobe acquisition makes the roadmap and pricing a question for a much larger company.

Pros

• +Keyword, traffic-estimate and backlink databases are Semrush's own, with historical data back to 2012 on higher tiers
• +AI-visibility tracking (ChatGPT, AI Overviews, AI Mode) is in the same project as keyword rankings from the $199 Starter plan
• +An API, a Chrome extension and an official Claude connector let the data leave the dashboard
• +A $0 plan and a seven-day trial on paid tiers mean the interface can be judged before paying
• +Terms name a single Delaware entity at a Boston address and were updated in August 2026 after the Adobe deal

Cons

• −Every plan is single-user; each extra seat starts at $45 per month on top
• −Keyword and prompt caps (500 keywords on the $139 and $199 plans) run out quickly across several sites
• −Traffic figures are estimates from clickstream models, and the gap from real analytics can be wide on small sites
• −Now part of Adobe, so pricing, packaging and data-sharing terms may change with the parent's enterprise strategy
