SimilarWeb estimates website traffic, traffic sources, audience demographics, and competitive benchmarking. It also helps in research and understanding competitor traffic volumes, referral sources, and audience overlap. It answers: how much traffic do our competitors get, and where does it come from?
Gravton Labs operates at a different layer. It answers: before anyone visits any website, what are buyers asking AI platforms, and which brand is being recommended?
SimilarWeb can tell you a competitor is getting more direct traffic, but it cannot tell you whether the cause is consistent AI citations during the research phase. Gravton fills that blind spot: SimilarWeb benchmarks the outcome (traffic), Gravton maps the cause (AI visibility that precedes and shapes traffic).

Methodology
SimilarWeb estimates traffic based on modelled panel and ISP data. Its accuracy varies by traffic volume.
Gravton's measurement is not an estimate. It records actual AI platform output at the prompt level. When a prompt sweep runs on ChatGPT and Perplexity, the results are the literal content of the AI responses, scored for brand presence, competitor presence, and sentiment. This is observed data, not modelled data, and it covers a channel that SimilarWeb cannot model at all because it predates the click.
Frequently Asked Questions
We use SimilarWeb to monitor competitor traffic spikes. Can Gravton help explain them?
Yes. If a competitor's direct or branded search traffic spikes, a common cause is an increase in AI citations during the research phase. Gravton can audit whether that competitor's AI visibility has improved and which prompt clusters have improved, giving you the strategic context behind the traffic signal.
Can Gravton's SDK connect AI session data to our analytics setup?
The Gravton SDK connects to GA4 and supports topical attribution, reclassifying AI-referred sessions that currently appear as direct traffic in standard analytics. Enterprise plans include custom data integrations.
Is Gravton useful for agencies managing competitive intelligence for clients?
Yes. Scale plan supports multiple brand voice profiles and seats. Enterprise supports multi-brand, multi-region tracking with white-labeled reporting.
Bottom line
For teams trying to diagnose competitive traffic gaps, SimilarWeb shows what happened. Gravton shows why by revealing the AI-layer recommendation patterns that increasingly drive branded search and direct traffic, even before a single click is recorded.
