Grounding AI in real data: live crawling and RAG vs. stale training
A model's training data is frozen in the past. For anything about the live web — your site, your rankings, today's numbers — you have to feed it fresh context. Here's how grounding works and when to use which kind.
Ask a raw model to audit your website's SEO and it will confidently describe a version of your site that may be months out of date, or invented entirely. The model isn't lying — it simply has no live access. Grounding is how you give it one.
Live crawling for the present
Our SEO and GEO agent runs a live crawler against the actual URL at request time. The model's recommendations are built on what's on the page right now — the current headings, metadata, and structure — not on a stale memory. When the answer has to reflect the live web, you fetch the live web.
Retrieval for your own knowledge
For a workspace's own material — brand voice, past campaigns, product notes — we use retrieval: the relevant pieces are pulled from a knowledge store and injected into the prompt. This is why the agents sound on-brand: the brand's actual voice examples travel into every generation instead of being approximated.
The rule of thumb
If the fact changes in real time, crawl or call an API for it. If it's your own stable knowledge, retrieve and inject it. If it's genuinely general reasoning, the model already has it. Most “the AI made something up” problems are really “we never gave it the real data” problems.
