Affiliate Promotions: Substantiate Claims Before Publishing Comparisons

Start with the claim, not the wording

Before drafting a comparison, write down the statements a reader might rely on to make a decision. These may include what an offer includes, who is eligible, what actions are required, how access works or how a plan differs from another. Separating claims from persuasive language makes it easier to identify which statements need evidence and which are clearly presented as your assessment.

Classify each statement as a directly documented fact, a calculation based on disclosed inputs, an opinion, or a prediction. A statement about a listed plan feature is different from a claim that a particular offer will produce a result for a reader. Predictions and outcome claims require particular caution because an individual’s results may depend on factors your comparison cannot establish.

• Mark each factual statement that could affect a reader’s decision.
• Separate facts, calculations, opinions and predictions.
• Remove claims whose meaning is unclear even before checking their evidence.

Build a source record for material facts

For each important factual claim, record where the information came from, when you checked it and what exact point it supports. First-party terms, offer pages and official program documentation can help establish what a program says about its own offer. Keep the source close to the claim in your editorial workflow so another reviewer can confirm the connection without repeating the entire research process.

A source does not support every sentence on a page simply because it relates to the same product. For example, documentation about an available feature does not establish that every user can access it under every plan. Match the wording to the scope, audience and conditions actually described. When the source is silent, do not fill the gap with an assumption.

Make comparisons specific and fair

A useful comparison identifies what is being compared and for whom the distinction matters. State the relevant plan, access model, eligibility condition or use case where the source provides that detail. Avoid using a single dimension, such as a headline feature, to imply that one offer is better for every reader. Different visitors may prioritize different terms, and a comparison should make those trade-offs visible.

Check that descriptions use equivalent criteria. If one offer is described with a current, detailed condition and another with a general summary, readers may receive an uneven picture. Make limitations visible near the related claim rather than burying them in a distant disclaimer. If the evidence does not allow a like-for-like comparison, say so and explain what information is missing.

Keep time-sensitive claims under review

Offer terms, eligibility, features and promotional rules can change. Record a review date for claims that could become outdated, and set a practical process for checking them again before republishing or materially updating a page. Do not present an old source as current evidence merely because a page has remained online.

When a claim cannot be rechecked, narrow it to what the available source actually establishes or remove it. Preserve a simple change note explaining what was checked and what changed. This helps editors distinguish an intentionally retained statement from one that has not been reviewed, and it reduces the risk of repeating an outdated claim across multiple pages.

Check program rules and visitor-facing context

Evidence quality is only one part of responsible affiliate publishing. Review program rules about claims, permitted promotion and required approvals before using offer language or creative assets. A claim can be factually supported and still conflict with a program’s conditions for promotion. Keep the program’s instructions and your editorial evidence record separate so each can be checked independently.

Present the affiliate relationship clearly where readers encounter the recommendation, in line with applicable disclosure requirements and the publisher’s policies. Do not let a disclosure substitute for substantiation: readers still need a fair description of what is known, what is uncertain and what conditions apply. Rules vary by jurisdiction and context, so seek qualified guidance for questions that require legal interpretation.

Use a publish-or-revise checklist

Before publication, review the page from the reader’s perspective. Can a visitor tell which statements are documented terms, which are editorial judgments and which conditions may affect eligibility? Are comparisons based on equivalent information? Does the page say what it cannot verify instead of turning uncertainty into a confident promise?

Keep the final review small enough to repeat. A checklist is most useful when it catches a specific failure, such as a claim without a source, a comparison with mismatched criteria or an expired term. If an item fails, revise the sentence, add a clear qualification supported by evidence, or remove it before publication.

• Every material factual claim has a traceable source and review date.
• Calculations show their inputs and method.
• Comparisons use comparable criteria and identify relevant conditions.
• Program promotional rules and disclosure requirements have been checked.
• Unsupported or outcome-guaranteeing claims have been removed.
