Why it happens
The page needs a login. Draft products, password-protected stores and members-only pages cannot be opened from outside. If you cannot open the link in a private browser window, neither can we. The store blocks outside readers. Some platforms block anything that is not a person with a browser. Nothing is wrong with your link — that store will not answer. The page is not a product page. A collection page, a category or a homepage listing several products does not have one product to read.The three ways round it
1
Check the link opens for a stranger
Copy it into a private or incognito window. If it asks you to log in, or shows nothing, that is the problem. Publish the product or use a different link.
2
Use a more specific link
If the page lists several products, open the one you mean and copy that address instead. Where a product was found but it is the wrong one, press Not right? Use a different link.
3
Type the details in yourself
Every route has this. On Autopilot it is No link? Add product details manually; in Manual Mode it is No link? Enter details manually.This works perfectly well. You are supplying what would have been read off the page — the name, what it does, what is good about it. Be specific about the problem it solves, because that is what the script is built from.
