How to Annotate Competitor Content for Gap Analysis

A content gap analysis compares what competitors cover with what you cover, to find topics and details you're missing. Annotating their pages as you read makes the comparison concrete instead of a vague impression.

1. Choose the pages

Search the topics you want to rank for and note the top three to five results. Include direct competitors and any site that ranks consistently, even if it's not a business rival.

2. Decide what to note

• Questions answered: list the sub-topics each page covers.
• Depth: where they give steps, examples, data or visuals.
• Weak spots: outdated facts, vague advice, missing steps.
• Format: tables, checklists, tools, videos.
• Angle: who the page is written for.

3. Use a simple tagging system

• GAP: something they cover that you don't.
• WEAK: something they cover poorly that you could do better.
• IDEA: a new angle or format to try.
• SOURCE: a study or statistic worth checking and citing.

4. Annotate as you read

Sticky Notes Anywhere lets you add notes directly on a competitor's page. They're saved for that page and listed in a side panel you can search, so typing "GAP" pulls up every gap across sites. Notes are stored on your computer, and you can export them to a backup file.

5. Compare with your own content

Put the findings into a simple table: topic, which competitors cover it, whether you do, and how well. Patterns stand out quickly, such as a question every competitor answers that you skip.

An example

Say you sell hiking gear and want to rank for "how to choose hiking boots." The top four results all explain boot types and fit. Three of them mention breaking boots in, but none explains how to test fit in a shop, and none has a sizing chart for wide feet. Those are gaps: your post can cover both, plus your own staff's fitting advice.

6. Turn notes into a plan

• Update existing posts to fill gaps; often the quickest win.
• Write new posts for topics you don't cover at all.
• Add formats such as a checklist or calculator where competitors have none.

Don't copy

The goal is to find what readers need that's missing, not to rewrite competitors' pages. Use their content to spot gaps, then answer them in your own words with your own experience.
