When social media posts aren’t readable for everyone: a common everyday problem
Many freelancers, agencies and marketing teams know the situation: an editorial calendar is full, images and videos must be produced and published quickly — and no one has time to add meaningful ALT text to every image, check color contrasts or create captions for short clips. Far too often accessibility remains an unloved add‑on. That can affect reach, user friendliness and, in the worst case, legal protection.
Why automatic accessibility checks make sense
Accessibility is not a one‑off project but part of ongoing content production. Two tasks are particularly time‑consuming: ALT texts/image descriptions and checking readability through color contrasts. Automated processes help standardize these routines while leaving human review where context and tone matter.
Marqentra on‑premise: Automatic ALT texts and contrast checks where your data resides
Marqentra integrates generation of ALT texts, automatic color contrast checks and the creation of accessible captions directly into your self‑hosted media library. That means: images and videos stay on your server; analysis and generation happen locally. For you this brings two concrete advantages:
- Data protection and control: No transfer of sensitive media to third parties; full control over assets and metadata.
- Workflow efficiency: ALT texts, image descriptions and contrast hints are already available in the media library before a post is scheduled or published.
How this concretely makes your daily work easier
Instead of describing every image manually, Marqentra generates a suggestion for the ALT text and inserts it as metadata into your media database. Editors only review and adjust what is contextually important. The contrast check flags problematic text‑on‑image combinations and gives precise suggestions for improvement (e.g. change color, add shadow, outline) — saving test runs and design iterations.
Practical workflow: From upload to publication
How to integrate accessibility checks into your existing content production without extra effort:
- 1. Upload: Images and videos are uploaded to your self-hosted Media Library as usual.
- 2. Automatic analysis: Marqentra automatically generates an ALT text suggestion, checks color contrasts and, if desired, creates raw captions for videos.
- 3. Editorial review: Editors see suggestions directly in the Media Library, can adjust texts, mark decorative images or add supplementary descriptions.
- 4. Integration into posts: Finished ALT texts and captions are applied to social posts or linked websites at the push of a button when publishing.
- 5. Monitoring & optimization: Analytics show how often content has been revised and where recurring issues occur — ideal for process optimization.
Practical examples: How your team uses the features
Agency: A social media agency manages several clients. Instead of coordinating ALT texts by e‑mail for each post, the team stores the images in the self-hosted library. ALT suggestions save time; the editorial team reviews at most 20% of cases and only refines where tone is important.
Small business owner: For a café owner, image descriptions are important to reach local customers with visual impairments. Marqentra provides clear, short ALT texts; contrast checks help make text on images readable — without external services or additional tools.
Tips to make automatically generated ALT texts and captions truly useful
- Check context: Have editors verify whether the ALT text fulfills the informational function — not every visual detail needs a full description; sometimes a short statement is sufficient.
- Keep it short and meaningful: Good ALT texts are concise: What is necessary for understanding? Who or what is visible? Avoid unnecessary adjectives.
- Mark decorative images: Images that are purely decorative should be labeled as such so screen readers skip them.
- Edit captions: Automatically generated captions save a lot of time but usually need a brief correction for names, technical terms or timestamps.
- Contrast measures: If contrast is low, consider suggesting text colors, backgrounds or simple CSS changes instead of redesigning the image entirely.
Why self-hosting makes a real difference here
Many accessibility tools are cloud-based and require uploading media-sensitive files to external providers. For companies with data-protection requirements, sensitive content or strict internal compliance rules, that is often not an option. A self-hosted system like Marqentra keeps all processes on your own server: you retain control over data, access rights and backups — while still using automation for accessible content.
Integration with existing systems
Marqentra runs independently on your web space or server and additionally offers Marqentra for WordPress for seamless integration into WordPress workflows. This makes it easier to adopt ALT texts and captions into websites or to schedule and automatically publish to linked social channels.
What you can expect from the implementation
Do not expect a substitute for editorial diligence: automation reduces routine work and provides reliable suggestions that free up time for high-quality post-editing. In practice, this speeds up production, increases the consistency of your accessibility metadata and minimizes technical errors before publication.
Conclusion: Integrate accessibility into the production flow — privacy-friendly and efficient
Accessible social posts are no longer an extra effort when ALT texts, contrast checks and captions are generated automatically where your media reside. Marqentra combines these functions in a self-hosted media library so your content becomes accessible faster, more consistently and under your control. This way you support your brand's accessibility while simultaneously reducing work time for routine tasks.
