get rich (maybe)
It might not be polite to discuss it, but money makes the world go round.
The strongest argument for accessibility isn't the legal requirement or the moral imperative (although those are very important and valid reasons), but the business case, demonstrated here by figures from Legal & General and Tesco.
Legal & General
When Legal & General redesigned their website with a focus on accessibility it was an undisputed success, resulting in:
- 50% increase in search engine traffic
- immediate 95% increase in requests for quotes
- 90% increase in completed applications
- 300% increase in take up for some products
- conversion rates doubled for the most important revenue generators
- 450% increase in earnings in the five days following the launch of a redesigned product
- longer term 135% increase in completed applications
- return on investment in five months
Tesco
Several years ago, Tesco received a number of complaints from users with sight problems who couldn't use their online grocery shopping service.
At the time, the fastest way for Tesco to make their grocery shopping service accessible was to create a separate version, Tesco Access, which cost £35,000.
Tesco expected that the site would only be used by blind and partially sighted users, but the site was found, and used, by a far wider audience. Before the Tesco Access site was decommissioned in favour of an integrated site, it was bringing in an income of £13million per year, which is a considerable return on investment.
