Alt-text for images
We write alternative text (alt) for images: so that blind users understand via a screen reader what is in a picture, and search engines index images better. So that images are not 'black holes' for those who cannot see them. Honestly upfront: alt quality depends on UNDERSTANDING the role of each image (informative or decorative, what is important in it), it is work by volume (the number of images), and when new images are added, alt must be written again; auto-generation is only a draft with limits.
Alt-text for images — overview

Alt-text for images is writing meaningful alternative descriptions for the site's images so that a screen reader conveys the essence to a blind user, and informative images are clear without visual context. We split images into informative (a descriptive alt is needed), decorative (an empty alt so the screen reader skips them) and functional (alt describes the action, e.g. an icon-button). Honestly about quality, this is key: a good alt is not 'photo', but a description of the ROLE and essence of the image in context: for the same image the alt can differ depending on why it is on the page. So understanding of the content is needed, not a mechanical caption. Honestly about auto-generation: automatic alt (AI recognition) is only a DRAFT: it often describes the wrong thing, errs in context and does not distinguish decorative from informative. We use it at most as a starting point and write it humanly. Honestly about volume: the price depends on the NUMBER of images — a site with 20 pictures and one with 2000 are different work. Honestly about the process: when new images are added, alt must be written again — this is maintenance, not a one-off point. Honestly about complex cases: for complex graphics (diagrams, charts, infographics) a short alt is not enough — an extended text alternative next to the image is needed; and if the image's purpose is unclear without you, we will ask for context (otherwise a meaningful alt cannot be written). Honestly about coverage: alt is just ONE component of accessibility; it helps blind users with images but does not replace the other measures (keyboard, contrast, screen readers). Honestly about the effect: critical for blind users + helps image SEO, but we do not guarantee direct sales growth. Honestly about access: access to the site/images and an understanding of their purpose are needed. An important boundary: this is alt for images; captions for video are 811, transcripts of audio are 812. Picture this: instead of 'an image is emptiness or a file name for a screen reader' — a clear description of the essence. The base price starts from 10,000 ₽ (depends on the number of images).
Problems we solve
- For a screen reader, images are emptiness or a file name.
- A blind user does not understand what is in an informative image.
- Decorative pictures are voiced in vain and get in the way.
- Images are poorly indexed by the search engine (no alt).

FAQ
Can alt be generated automatically without paying for manual work?
Auto-generation (AI) is only a draft: it often describes the wrong thing in context, errs and does not distinguish decorative from informative. For real accessibility, alt must reflect the ROLE of the image on the page, and that requires understanding. We can take auto as a starting point, but write it humanly.
Why does the price depend on the number of pictures?
Because it is work by volume: writing a meaningful alt for 20 images and for 2000 is different work. We will honestly calculate by your number in advance. And we will account for decorative pictures needing an empty alt — that is also part of the work, not a skip.
Is this a one-off job?
Basically yes, but when new images are added, they also need alt — otherwise 'mute' pictures appear again. This is maintenance as the site grows. We will give your team simple rules so new pictures get a correct alt right away.
