SaaS landing pages written at a 5th-to-7th grade reading level convert at 12.9%. The same pages written at a "professional" reading level convert at just 2.1% - a 514% difference.

It is the clearest sign yet that dense, jargon-heavy copy quietly kills conversions. The pages that win are not dumbed down; they are simply readable - short sentences, plain words, one idea at a time - so a busy buyer grasps the value in seconds instead of decoding it.

If your landing page reads like a product spec sheet, that is likely leaving conversions on the table. Paste your headline and first paragraph into a readability checker before you touch anything else - lowering the reading level is one of the cheapest, highest-leverage tests you can run.
