I addressed rich snippets last week, explaining how they can enhance organic search listings for ecommerce product pages. Structured snippets are similar in concept, but they don’t receive as much attention in the context of organic search.
I’ll address structured snippets in this post.
Structured snippets provide additional information in organic listings. Google extracts the info from on-page tabular data — i.e., data marked up within <table> HTML tags.
Rich snippets and structure snippets are easily confused. Both stand out in organic search listings. But rich snippets come from structured data such as Schema.org, whereas structured snippets come from an HTML table.
Structured snippets are less predictable than rich snippets as Google may ignore an HTML table and thus the snippet. Google almost generates a rich snippet if the on-page markup is correct.
The good news is Google often combines structured and rich snippets when it encounters both on a web page.
HTML tables typically organize numeric data, which Google views as factual. Yet, in reality, structured snippets extend beyond numbers. They can display a product’s specifications, benefits, and even pricing.
All of those details make a snippet “shoppable,” in that it conveys expectations for the page and otherwise match buying intent, ensuring that whoever clicks on the listing is interested in the product.
And here’s the on-page table (below) that generated the structured snippet above. It’s an excellent example of the uncertainty surrounding which part of the table Google will choose to extract.
The screenshot below is a structured snippet that summarizes a list. On-page HTML tables that show the options and features are effective search-optimization techniques for product and product category pages.
And here’s the on-page table that Google used to extract the info.
And, yes, Bing also supports structured snippets in the same manner — extracting data from tables and adding it inside organic search listings.
Structured snippets, like rich snippets, are the low-hanging fruit of search engine optimization. Structured snippets require no monetary investment. Just add HTML tables and hope Google extracts the info.
Experiment with various HTML table formats, such as comparisons and feature summaries. Implement tables via manual code (using an HTML widget, for example) or via plugins or custom apps from your content management or ecommerce platform. Many platforms support tabular data for product and category pages.
