Claude is Anthropic's AI assistant. It leans on what it already knows and searches the web when a question calls for it. In our tracking it searches on about half of its prompts and answers the rest from memory, so its training still shapes much of what it says about your market.
Centium tracks Claude on every plan, alongside six other models. What follows are trends from our tracking rather than rules, and we will update this page as they shift.
How Claude answers
A model's training data is a snapshot of the web up to a cutoff date, and the model reaches people months after that. When a question can be answered from that snapshot, Claude usually answers it directly. When a question depends on something local, recent, or specific that it is unsure of, it searches first.
When Claude searches, it turns the question into searches of its own, the same query fan-out we measure across every model, and reads the pages it finds. It rarely searches more than twice for one answer.
What we're seeing
It searches less than most. Claude answers about half of its prompts without searching. Most of the other models we track reach for the web more often, so more of what Claude says about a category comes from what it learned in training.
Local and fast-changing questions send it to the web. In our tracking it searched on nearly every question about local services, like a repair shop or a contractor in a named city, and on questions that change year to year. It rarely searched on evergreen questions, like the best ski towns for a long weekend.
Search is how newer and local brands get in. Brands Claude never named from memory showed up in about 1 in 5 answers once it could search. Brands it already knew held steady. For a business Claude's training missed, being easy to find is what puts it in the answer.
It rewards a long web history. When it answers from memory, Claude tends to name brands that were widely covered before its training cutoff. Newer brands and recent launches show up less there, even when they lead their category today.
It describes you the way the web did. How Claude talks about a brand tends to echo how that brand was described across many pages at once. A consistent story across sources gives it a clearer one to repeat.
Claude knowledge cutoff
Each Claude model is trained on data up to a cutoff date, and each newer model moves it forward. Anthropic publishes two figures. The reliable knowledge cutoff is the point through which the model's knowledge is most complete and dependable. The training data cutoff is the most recent date in its training set, and it is the date your Centium dashboard reports. Search covers some of what came after. Here is how the Sonnet line compares, including the model Centium tracks.

How to show up in Claude
Claude works from two things: what it learned in training, and what it finds when it searches. Work on both.
- Be in the data models train on. Most models learn from Common Crawl, the open archive of the web. Check whether your site is in it with our free training data checker.
- Let Anthropic's crawlers in. ClaudeBot collects content for training, and Claude-SearchBot indexes pages for Claude's search. Check your robots.txt with our free AI crawler checker.
- Be easy to find for the questions it searches. Local and time-sensitive questions send Claude to the web. Current listings, up-to-date pages on your site, and recent coverage are what it finds there.
- Get covered where it will last. Expert reviews, category publications, and reference sites are the pages most likely to be in the next training set. A lasting write-up does more here than a short campaign.
- Say the same thing everywhere. State what you make, who it is for, and why it stands out the same way on your site, your listings, and your press. That consistency is what the next model learns.
- Measure over time. What Claude finds in search can move week to week, while what it learned moves when a new model arrives. Track your visibility so you see both.
Tracking your AI visibility in Claude
Claude is one of seven models Centium runs on every plan. Each report shows how often Claude names your brand, which competitors it names instead, where you land in its answers, how it describes you, and which sources it cites, next to the same numbers for every other model. Plans start at $99 a month.
