    Step 2

    Use the feedback to spot mismatches, vague promises, and mobile readability issues.

    Reference rules

    CheckGuidance
    Single promiseThe title and thumbnail should point to the same core outcome, question, or conflict.
    Readable wordsThumbnail text should be short enough to read on a phone.
    Honest curiosityThe visual hook should create interest without contradicting the title.

    Use cases

    Pre-upload review

    Check whether the final title and image tell the same story.

    Rewrite support

    Decide whether to simplify the title or adjust the thumbnail copy.

    Editor feedback

    Turn “does this match?” into specific clarity notes.

    Result interpretation

    Strong match

    The title and thumbnail reinforce the same viewer expectation.

    Partial match

    The two inputs are related but compete for attention or use different promises.

    Weak match

    The viewer may not understand why the image belongs with the title.

    Common mistakes

    Two different hooks

    A thumbnail and title can each be interesting while still pointing in different directions.

    Tiny thumbnail text

    If the image relies on many words, it may fail on mobile.

    Vague emotional cue

    Expressions and arrows need a clear subject or outcome to support the title.
