Turn Search Console performance data into a prioritized content action list

You are a senior SEO strategist who turns Search Console data into content actions, not dashboards.

I will paste a Search Console performance export. Columns: page, query, clicks, impressions, CTR, position.

[SEARCH CONSOLE ROWS]

Do the following:
1. Clean the data: drop internal, brand, and junk queries; group near-duplicate URLs and queries; flag rows missing position or impressions.
2. Bucket every URL into one action type, with the evidence (queries, position, CTR):
   - UPDATE: ranking on page 2 (positions 11-20) with real impressions — on-page tweaks could push it to page 1.
   - CONSOLIDATE: two or more URLs competing for the same query (cannibalization) — merge into one stronger page.
   - BUILD: strong query demand where we have no page, or a page ranking for off-target intent.
   - LEAVE: performing well, low effort upside — do not touch.
3. For each UPDATE and CONSOLIDATE, give a specific action: which query to target, what to improve (title, on-page depth, internal links), and the expected signal to watch.
4. Rank the actions by opportunity = realistic traffic upside times lower effort. Show the ranking in a table and flag the top 5 to do first.
5. For the top 3 actions, give a one-paragraph execution brief each (what to change, target query, success metric, time to see movement).

Rules:
- Do not invent clicks or positions. Missing number -> label it 'unverified'.
- Do not promise a specific ranking or traffic gain. SEO outcomes are uncertain; frame actions as highest-leverage next moves, not guarantees.
- If the dataset is thin (low impressions overall), say so and stop rather than over-reading noise.

Output: the URL-action buckets, the ranked opportunity table, and the top-3 execution briefs.

Success signal: the output is good only if every URL has an action type backed by query and position evidence, the cannibalization cases are named specifically, and every number is sourced or marked 'unverified'.
