SEO Tips for ALT Tags in 2024

It is advisable to maintain an ALT Tag of 125 characters or less both for screen readers and for best practice SEO.

Those ALT Tags marked in orange are above 125 characters in length.

Although widely debated, it is understood that some popular screen readers for the visually impaired cut image ALT text off after around 125 characters. While no longer a hard and fast rule, it is still a good practice for SEO as this keeps the ALT tags clear, and concise but still keeps them descriptive of the image on the page.

Note: Some images may not display correctly if coded in bespoke CSS rather than standard image tags, however any image ALT tags may still display and any size guidance for these are still relevant and should be investigated further.
