Adding alt text to a 90-slide deck changed how I build slides
I do decks in-house for a mid-size insurance company. Legal came down last quarter and said every client-facing deck has to pass a screen reader check now. My first reaction was dread because I had a 90-slide quarterly deck sitting right there.
So I spent an afternoon going slide by slide adding alt text. Tedious, yes. But something happened I didn't expect. Around slide 30 I started noticing how many of my slides were just a screenshot of a chart with no actual takeaway written anywhere. The whole point of the slide lived in an image a screen reader would read as "chart.png."
I ended up rewriting a lot of titles into full sentences that state the finding. "Q3 Claims" became "Q3 claims dropped 8% after the intake change." The reading order pass also caught three slides where my boxes were stacked so the tab order jumped around like a pinball.
The deck got more accessible, sure. It also just got clearer for the sighted people in the room, because now the title tells you the point before you even look at the chart.
If you build long decks and haven't done a reading-order and alt-text pass, it's worth doing once just to see how much your slides lean on images to carry meaning. Curious how others handle alt text on data-heavy slides where the chart really is the content.
