Competitor content gap from sitemaps

Competitors' sitemaps are public. Diffing them against the user's sitemap reveals exactly what they publish that the user does not — URLs are the units, no API key needed.

When to use

• "Compare my content to competitor.com"
• "Find my content gaps vs these 3 sites"
• Building a content roadmap from competitor coverage.

When NOT to use

• Competitor has no sitemap or blocks it — nothing to diff.
• The user wants rank positions (who ranks #1 for X) — that is the

rank-tracking skill, not a sitemap diff.

Setup

pip install zens-ink

Commands

# Single competitor vs you
python3 -m zens_ink.competitor_gap --url https://competitor.com/sitemap.xml
 
# Multiple competitors at once, diff against all
python3 -m zens_ink.competitor_gap --compare \
  https://rival1.com/sitemap.xml https://rival2.com/sitemap.xml --lang en
 
# Then: prioritize the gap into a ranked matrix
python3 -m zens_ink.content_matrix \
  --scores opportunities.csv \
  --clusters clusters.json \
  --csv content-matrix.csv

scores comes from the keyword-research skill (kgr_auto CSV), clusters from keyword_cluster JSON — pipe the two skills into this one.

How to read the results

• URLs only the competitor has = topic-level gaps. Read their slug patterns:

a /glossary/ tree means a whole content program, not one page to copy.

• Filter by --lang when competitors are multilingual, or the diff fills

with translated duplicates.

• The matrix ranks by expected value per hour of work — top rows are the

first posts to write. Do not work alphabetically.

Next steps

• Before writing each gap page: search-intent (right page type) then

keyword-difficulty (winnable?).
