How do we use Profound alongside Collimer and search data?
No single number gives the full picture, so we read three signals together.
- Collimer. What five assistants say about your company on the questions your buyers ask, and the pages that would change the answer.
- Profound. Ongoing measurement of mentions and citations across assistants, and which AI crawlers reach your site.
- Search data. Rankings, clicks and queries. Assistants that browse the web start from search results, so these numbers show whether a page can be found at all.
Together they are the read. The sprint is what we do with it: decide what your company should say, then write it. If you already use Profound, we work from its numbers. If you do not, Collimer's read is enough to start.
Which one do I need?
Do I need Sandcastle Labs if I already use Profound?
If your team has the time and the strategy to act on what Profound shows, maybe not. If the numbers are clear and the pages that would change them are not getting written, that is the gap we fill. We start with your manifesto, then write and ship the pages alongside your team.
Do I need Profound if I work with Sandcastle Labs?
No. Collimer gives every sprint a dated read of five assistants, and that is enough to start. Profound is useful when you want ongoing measurement across more assistants, or want to see which AI crawlers visit your site. We work from its numbers if you have them.
