Just days after Zineb Ait, webmaster trends analyst at
To gain some sense of the requirements for Google showing your rich snippets in the search results it is useful to take a look at the wording Ait used in response to a question on Twitter as to why Rich Snippets are not showing.
It is useful to summarize the findings first, as the translations of Ait's conversation are not the best:
- Rich Snippets displaying in the SERPs depend on the Quality and Relevance of the page.
- If satisfactory, it can take 24 hours for the Rich Snippets to appear.
- The Quality of the page is compared to other websites which appear for that search query, as they try not to clutter the search results with Rich Snippets. Therefore, there is no guarantee your rich snippets will appear for all queries.
From our own experience, we know that websites affected by a Google Panda Penalty will lose their Rich Snippets showing in the SERPs. We suspect, therefore, that the quality of the website is also a factor rather than just the page quality. Furthermore, it is now important to make sure your content is better than your competition as limitations on the number of Rich Snippets showing for any search query seems to now be a factor.
You can see the full conversation, and translations using "Google Translate" below:
@Kevin_Monier Hello. C'est plus une question de qualités de la page et de pertinence des romich snippets que de délai— Zineb Ait (@Missiz_Z) February 16, 2016
@Kevin_Monier Si la page est jugée qualitative et que l'algo juge que les rich snippets amélioreront l'UX, ca peut prendre moins de 24h— Zineb Ait (@Missiz_Z) February 16, 2016
Kevin: Any idea of the time (according to your exp.) Avg. for displaying Rich Snippets in the SERPs?
Ait: It's more a question of quality and relevance page snippets [Romich] that time
Ait: Kevin_Monier If the page is considered qualitative and that the algorithm determines that the rich snippets will improve UX, can take less than 24 hours
@Kevin_Monier apparemment pas :( aussi il faut savoir que l'affichage depend de la requete. Une requete site: par ex ne marchera pas— Zineb Ait (@Missiz_Z) February 16, 2016
@Kevin_Monier enfin, nous essayons de ne pas trop "encombrer" les SERPs avec trop de sites avec RS. Du coup, vos critères sont à évaluer (1)— Zineb Ait (@Missiz_Z) February 16, 2016
@Kevin_Monier (2) par rapport aux autres sites affichés pour la même requête.— Zineb Ait (@Missiz_Z) February 16, 2016
Kevin: I thank you Zineb well that in mind but also the pages well meet both criteria. : /
Ait: Kevin_Monier Apparently not too :( be aware that the display of the Rich Snippets depends on the website request. Eg will not work
Ait: Finally, we try not to over " cluttering " the SERPs with too many websites with RS. So, your criteria are to assess compared to other websites displayed for the same query.
@Kevin_Monier il faut laisser faire l'alhorithme et attendre, tout en continuant a optimiser le contenu. Les serps fluctuent.— Zineb Ait (@Missiz_Z) February 16, 2016
Kevin: Hello yes I know that indeed some abuse the microdata but I think on our pages are relevant queries.
Ait: Must let the algorithm and wait while continuing to optimize the content. The SERPs fluctuate.
MozCast Review Snippet Statistics
Just one day after Zineb's Twitter conversation, Dr. Pete Meyers at Moz noticed a drop in Review Snippets showing in the SERPs:
Looks like a drop in SERPs with review snippets sometime in the past 24 hours -- https://t.co/zezk9DUD3r— Dr. Pete Meyers (@dr_pete) February 17, 2016
You will see below a copy of the Review Rich Snippet data showing the falls continuing for a further day:
It is not clear whether the two events are related, but it is possible that the discussion on Twitter prompted some testing by Google.
