Quick answer
Describe the image's useful content and purpose in the context of the post. Include essential text shown only in the image. Skip phrases such as 'image of' unless the medium matters. Do not stuff keywords, repeat the full caption, or invent details that are not visible.
Source check: August 28, 2026. Platform apps, APIs, account types, and third-party publishers can change on different schedules. The final operational check is the preview and public result in the exact path you use.
At a glance
| Surface or choice | Size or limit | Ratio or source | What it means |
|---|---|---|---|
| Photo | Subject, action, setting, relevant detail | Appearance details that do not help the post | |
| Text graphic | Essential words and what the layout adds | Repeating decorative marks | |
| Chart | Main comparison, direction, and key values | Listing every grid line | |
| Carousel | One useful description per slide or a complete caption alternative | One vague description for the full set | |
| Decorative image | Empty alt where the platform and context support it | A description that adds noise |
What this page owns
Alt text is not a hidden caption for search engines. It is a text alternative for someone who cannot use the image as shown. The best wording depends on what the image contributes to this post.
That ownership boundary matters. Boomp uses one clear page for each search job instead of publishing near-duplicate pages that give different answers to the same question.
A dependable production method
- Identify the image's job.
- State the useful visual information.
- Include essential embedded words.
- Keep claims within what is visible and verified.
- Check the platform's current alt-text field before publishing.
The last check matters most. A design file, successful export, scheduler acceptance, or API response does not prove that the customer-facing artifact is correct.
Size is only one acceptance test
A technically valid file can still fail the business. Check these questions with the final media and caption together:
- Is every name, date, price, claim, location, and link current?
- Does the crop preserve the subject and the useful words?
- Are captions, contrast, and text alternatives sufficient for the content?
- Does the business have permission to use the people, customer material, music, footage, and marks shown?
- Does the call to action match the destination and what happens next?
- Did a responsible person approve this exact version?
For the full release gate, use the social media content quality checklist.
Where Boomp fits
Boomp fits when the recurring problem is larger than one pixel count. The current first look starts with a public website and returns up to six website-grounded talking points before email. Those talking points are not finished posts and do not prove that Boomp knows the owner's voice. Email saves the first look and continues into post ideas. Finished media and posts belong to paid work, with the customer's approval settings controlling what represents the business.
Give Boomp your public website and review the first talking points before email.
