A readability score rates how easy your text is to read. It looks at sentence length and word length. Short sentences with plain words score well. Long dense sentences score poorly.
Writers use these scores to reach wider audiences. A clear page keeps readers on the page longer. That extra time helps your rankings too. Clarity is good writing and good SEO.
Better scores mean more readers finish your page. Finished pages earn more shares and links. Small writing changes add up fast. Start with the fixes in this guide.
Most formulas count two simple things. Average words per sentence comes first. Average syllables per word comes second. Long sentences full of long words score badly.
The result maps to a school grade level. Grade eight means an eighth grader can read it. Most web readers prefer grade six to eight. News sites aim even lower.
Scores never judge your ideas or facts. A brilliant essay can score poorly. A dull page can score well. Use the score as a guide not a verdict.
Flesch Reading Ease is the best known formula. It scores text from zero to one hundred. Higher numbers mean easier reading. Aim for sixty or above on the web.
Flesch Kincaid Grade Level gives a school grade. It pairs well with the ease score. Most tools show both numbers together. Grade seven to eight suits general audiences.
Gunning Fog and SMOG count complex words instead. They suit longer documents and reports. Blog posts rarely need these two. Stick with Flesch for web content.
For blogs aim for a Flesch score above sixty. Product pages can aim even higher. Simple words sell better than clever ones. Shoppers skim so make skimming easy.
Technical topics get some slack from readers. A medical guide will score lower by nature. Still trim every sentence you can. Clear beats impressive in every field.
Check competitors who rank well for your keyword. Match or beat their reading level. If they write simply you must too. Readers choose the easier page.
Run the check on old posts too. Older content often scores worse. A quick rewrite can lift stale pages. Small edits compound across a whole site.
Cut long sentences into two short ones. Twenty words is a good ceiling. Read each sentence out loud. If you gasp for air then split it.
Swap long words for short ones. Use beats utilize every time. Buy beats purchase in most cases. Plain words feel honest and direct.
Break walls of text into small chunks. Three sentences make a fine paragraph online. Add subheadings every few paragraphs. White space rests tired eyes.
Use short paragraphs to guide tired eyes. Big blocks push readers away fast. Two to three sentences fill a screen nicely. White space is part of good writing.
Passive voice adds words without adding meaning. The report was written by the team drags on. The team wrote the report says it faster. Active verbs tighten every sentence.
Intro phrases pad sentences for no reason. In order to can become to. Due to the fact that can become because. Cut filler and keep the point.
Stacked adjectives slow readers down too. Very extremely quite add little value. One strong word beats three weak ones. Trust nouns and verbs to carry weight.
Read widely to build a plain style. Notice how good writers keep sentences short. Copy their rhythm in your own drafts. Plain style is a trained habit.
Long introductions bury the main point. Readers decide in seconds whether to stay. State your point in the first lines. Then explain it with short clear sentences.
