Rich snippets spam is when you misuse structured data to (try to) gain an edge in the SERPs.
Rich snippet spam is bad because:
It can lead to a Google penalty. Google says pages or sites violating their structured data guidelines “may receive less favorable ranking.” They also apply manual actions to pages they find to contain “spammy structured data.”
It can lead to rich snippet ineligibility. Rich snippets often improve clickthrough rates in the SERPs. That’s why people want them, and it’s why rich snippet spam is a thing. But Google says your page or site may be “marked as ineligible for rich results in google search” if you violate their structured markup guidelines.
It rarely works. Google is pretty good at spotting spammy and irrelevant structured data these days (unlike a few years ago). So you’re unlikely to see rich snippets based on irrelevant or spammy markup appearing in Google search results anyway.
What should you do instead?
Include accurate structured data on your pages where relevant by following Google’s structured data guidelines.
Dividing the workload like this whatsapp number list allows both the vendor and the affiliate to focus on their strengths. The improvements are similar on desktop and mobile. Most of the focus in 2021 was on mobile results.
Google says that this helps them to “understand the content of the page.”
Following the rules also increases your chances of being included in special search result features and enhancements.
