The short answer
Choose comparison columns from the reader's decision, and label unavailable information explicitly. A table should make differences easier to inspect without flattening distinct services into one score. Include scope and source context when a number could otherwise look more comparable than it really is.
A worked example
A fictional publication comparison includes topic, writing scope, placement price and metric date. Two sites can have similar prices but different revision responsibilities. A reader can now see the missing editorial answer rather than treating the cheaper row as automatically better. These are planning criteria, not a validated publisher ranking model.
A practical checklist
- List the questions the reader must answer before choosing. Turn only the repeatable fields into columns, keeping nuanced explanations nearby.
- Use consistent units and distinguish missing, not applicable and zero. Do not hide a missing writing option behind an apparently complete total.
- Check the table on a narrow screen and with assistive technology. Preserve headings and a clear relationship between each field and its publication.
What to avoid
Avoid calculating a single 'best' score from unrelated authority, traffic and price inputs without an explicit justified model. A professional comparison can show trade-offs and uncertainty rather than announce a winner. Add narrative context when the table alone cannot explain a material difference.
A useful follow-up
Is a comparison table enough to recommend a publication?
No. It organizes evidence; editorial fit and unresolved commercial details still need judgment.
