What the link adds, and what it can’t
A product page is written for someone who has already clicked. It has a title, a price, gallery photos made for zooming and a bullet list that tries to answer every question at once. A 15-second ad has the opposite job. It reaches people who have never heard of the product, and it has time for roughly one idea. Treat the link as source material, not as a script.
In Blurbly the link supplies the product name, the price and the selling points. The picture comes from the photo you upload: the Generate button stays grey until at least one product photo is attached, which we ran into ourselves while writing the link-to-video tutorial. That split works in your favour. The page keeps the facts straight, and your photo decides what the product looks like in every shot.
Some pages can’t be read at all. If yours sits behind a login or a bot check, Blurbly plans from your photo and your sentence alone, and you’ll notice because the price or the product name is missing from the plan. Type them into the sentence and plan again.
