Spend less time on manual content creation. VidyBack auto-generates and schedules product videos straight from your Shopify catalog, so your best-written listings get seen, not just read.
See How VidyBack WorksShoppers don't read product pages the way they'd read an article, they scan them, deciding in seconds whether to keep reading, add to cart, or bounce, especially on a phone screen. Copy that's easy to skim, short sentences, plain words, gets the key selling points across before that decision happens. Dense, jargon-heavy paragraphs are more likely to be skipped entirely, which means the effort spent writing them never actually reaches the shopper.
Product and collection pages generally perform best around a 60-80 Flesch Reading Ease score, conversational, roughly 6th-8th grade level. Blog content can comfortably run a bit denser, since readers arrive already engaged and willing to spend more time. Legal text, privacy policies, terms of service, naturally scores low on any readability formula, and that's expected; it's optimizing for precision, not skimmability, so don't apply the same 60-80 target there.
"Our meticulously engineered ergonomic office chair utilizes premium-grade breathable mesh fabrication in conjunction with an adjustable lumbar support mechanism, thereby facilitating optimal postural alignment throughout extended periods of seated productivity."
"This ergonomic office chair keeps you comfortable all day. Breathable mesh fabric stays cool. Adjustable lumbar support keeps your back aligned, even on long work days."
Same product, same features, dramatically easier to skim, just by shortening sentences and swapping "utilizes premium-grade breathable mesh fabrication" for "breathable mesh fabric."
Most ecommerce product copy performs best in the 60-80 range, conversational and skimmable. Scores below 50 usually mean the copy has drifted into dense, jargon-heavy writing that's harder to skim on a phone, which is where most shopping happens.
Indirectly, yes. Shoppers scan product pages in seconds rather than reading carefully, especially on mobile, so copy that's easy to skim gets the key selling points across before they bounce. Dense paragraphs full of long sentences and jargon are more likely to be skipped entirely.
No, and no browser-based tool's is without a full pronunciation dictionary. This tool uses a standard vowel-group counting heuristic, which is accurate for the large majority of English words but can be off by one syllable on unusual or irregular words. Treat the score as a strong estimate, not an exact measurement.
They're calculated from the same underlying sentence-length and syllable-count data, just expressed differently. Flesch Reading Ease is a 0-100 score where higher means easier to read. Flesch-Kincaid Grade Level converts that into an approximate US school grade level needed to easily understand the text.
