How to Make Your Writing Easier to Read
Split long sentences
Keep most sentences under 20 words. One idea per sentence.
Use short words
"Use" not "utilise", "help" not "facilitate", "start" not "commence".
Prefer active voice
"Our trainers teach SEO" is clearer than "SEO is taught by our trainers".
Short paragraphs
2 to 4 lines each. Phone screens make long paragraphs look like a wall of text.
Check your keywords too
Easy reading and natural keywords go together. Test with our keyword density checker.
Scores are a guide
The formula only counts lengths. Always read your text aloud as the final check.
