Value my time.

the right time

results strategy to play
the SEO game.
Have a search results
strategy to minimise pain.

Jargon/idioms are difficult for:
• anyone not used to those
terms
• anyone reading in a second
language
• people with autism
Readability guidelines:
using clear language
helps everybody
Helps people in a hurry
Simply written content is easier to
scan and understand.
Helps for cognitive impairments
Easy to understand words and
sentences need less cognitive
effort.
Helps for motor impairments
Clear navigation labels and
headings means less clicking and
scrolling.
Helps for visual impairments
Short and simple sentences
convey meaning in a smaller
visual field.
Generally, people want to
understand.

Not marvel at your
language skills.
You don’t have to be
boring to be clear.
Just do it
#LikeaGirl
You don’t have to use
formatting or tricks to
stand out.
Change your sentence length and
punctuation.
Carefully.
Or you can use space.
Do this.
Then leave a space.
It’s okay to allow people
to think.
Struggling through content is
not a success metric
Accessibility is more
than code and colours.
You won’t lose people by
communicating well.
It’s not dumbing down.
It’s opening up.
