Turn a topic into a content brief with search-intent notes

Act as a senior SEO content strategist. I need a content brief for a page targeting: best project management software for agencies

Audience: marketing agency owners with 5-20 employees
Business context: we sell a project management SaaS with a 14-day free trial
Target length: 1,800-2,200 words

Do this in order:

1. Classify search intent. State whether this query is informational, commercial-investigation, transactional, or navigational, and justify it in one sentence based on what kind of page would actually satisfy it.
2. List the SERP features likely present (featured snippet, People Also Ask, AI Overview, video carousel, local pack, shopping results) and what each implies about the format the winning page needs.
3. Build a heading outline (H1-H3) that answers the query completely at the depth this intent expects — not padded, not thin. For every H2, note in brackets what job that section does for the reader, e.g. "[addresses the objection that stops conversion]".
4. List the sub-questions a genuinely thorough page would answer that the searcher hasn't typed but is implicitly asking — the unstated-intent layer.
5. Flag the E-E-A-T signals worth including: what experience, credentials, data, or first-hand specifics would make this page read as more trustworthy than a rewrite of the top 10 results.
6. Name one differentiation angle — something the top-ranking pages are likely missing that my business context makes uniquely easy to include.

Output as a structured brief with clear section headers, not prose paragraphs.
