Understanding Warning priceValidUntil In The Structured Data & Data Testing Tool
The priceValidUntil is not a new attribute and has existed for many years. However, you might think it is new due to Google’s structured data testing tool, giving you warnings since the end of last year.
When seeing warnings (not errors) in Google’s structured data testing tool it is there to notify you of optional data. This means there is no requirement, it also means there will be no SEO penalty. It also means only fill in the attribute value if it is appropriate.
The most common fix is to add a fabricated end date, this is actually wrong. You are essentially saying your product’s price will expire at your given end date. A golden rule is to never submit fake, fabricated or inaccurate data just to make yourself feel it’s resolved, just because the warning is removed.
What Is priceValidUntil?
The date after which the price is no longer available.
When Should I Use It?
You can use the priceValidUntil attribute if you have a price drop and you know when this price drop ends. Then remove it when the price is back to normal.
Always submit accurate data, if you can’t don’t add it. All pages with warnings are still marked as valid!
