The Meta Description is the copy that shows up beneath the page title and link within search results to provide some more context behind what that page is all about. See the example below from the Merchstack homepage.
The Meta Description is defined by a <meta> tag within the <head> element of your page. Sticking with our example from above, this is what the Meta Description tag looks like:
Every page can have a Meta Description, though not every page does. You can easily use your browser's developer tools or web inspector to find a page's Meta Description. There are other tools and plugins out there that make this even easier, but we'll explore those in another post.
The quality of your meta description doesn't directly impact your ranking (i.e. it isn't included in the algorithm that establishes your ranking). However, meta descriptions do influence the likelihood of a customer clicking into your page (measured by the click-through rate, or CTR). Your CTR is factored into Google's algorithm that determines your ranking for a specific keyword. Google will compare your CTR with the CTR of other pages above and below yours in the search results for the same keyword. If you're able to entice more customers to click into your page with a relevant and engaging meta description than the results above you, you will likely overtake those pages over time.
Think of meta descriptions like your “shop window”. If your shop window looks better than the shops next to you, it's more likely customers will enter your store. This is the same concept when applied to the Search Engine Results Page (SERP), but instead of a physical shop window, you've got 160 characters within your Meta Description to achieve the same effect. Your goal is to make your “shop window” as relevant and enticing as possible to attract more customers. The more customers you attract, the more likely it is you can compete for better and better positioning on the “SERP Street”. Unlike in the physical world, this competition for positioning, footfall, and relevancy is happening continuously, and locations (search rankings) are constantly changing. As Google starts to see relative over/underperformance amongst stores competing for a given keyword, the algorithm will adjust to ensure the best-performing pages move towards the top. Ranking higher is like being able to move your shop to the best position on the street. This should mean more footfall and more customers.
It's worth noting, as with most SEO components with an eCommerce store, there are no guarantees. Your performance will be impacted by better Meta Descriptions in two key ways:
The impact will vary across keywords and be impacted by all other factors that play into your CTR, and, more broadly, your SERP rankings. But, if you perform better than those results above you, it certainly puts you in a great position to start to move up the SERP. This means Meta Descriptions are important and worth spending the time to get right, alongside other key elements of the SERP, like Page Titles, H1s and Breadcrumbs.
Let's explore a quick example of Meta Descriptions in eCommerce. Suppose someone searched for “Grill Pans”.
The below results are taken directly from the SERP for “Grill Pans”. The second column is the Meta Description that was defined on each of those pages.
There are a few interesting items to note from the table above. 3/5 of the results are using the site-defined Meta Descriptions.
As we'll explore further below, it's not always a bad thing if Google overwrites your Meta Description. In this study by Portent, Google was found to overwrite Meta Descriptions 70% of the time. It would be interesting to further this research to understand how often eCommerce Meta Descriptions are overwritten, especially for PLP pages. In our example above, 80% of the Meta Descriptions were not overwritten, but that's clearly not a statistically significant sample set.
The question of what a “good” meta description is comes down to time and resources. High-quality, customized, unique meta descriptions would be ideal, but the time and expense required to create and maintain these descriptions over time is likely impractical for most eCommerce stores. A small multi-brand retailer can easily have 10,000+ pages on their eCommerce store, whereas medium to large eCommerce stores can have hundreds of thousands or even millions of pages. That's a lot of meta descriptions!
Let's revisit our Grill Pans results from above. We've added a column here which identifies the “Approach” these brands are taking with their meta descriptions. As you can see, there are many approaches. Bed Bath and Beyond use a narrative about hearty meals. Walmart layers in product details from that PLP. Home Depot talks about shop perks like free shipping. The Cooks Illustrated result was overwritten, so there was no “approach” so to speak. And the Williams Sonoma page adopts a brand-led approach. All of these are valid approaches. There is no objectively best approach, and the approach that's best for you and your customers would require testing and validation to confirm.
It is perfectly reasonable to adopt a formulaic approach to constructing meta descriptions. It is near certain that the Walmart, Home Depot, and Williams Sonoma meta descriptions from the graphic above are formulaically constructed. Good, bespoke meta descriptions per PLP or PDP will always be better, but when you factor in time, resource, and benefit, a formulaic approach often makes the most sense.
So for a Product Detail Page (PDP), a hypothetical formula and completed example might look something like this...
And for a Product Listing Page (PLP), you might have something like this...
You can take all of this one step further and auto-generate meta descriptions. There are a few products in the market that enable a flavor of automated meta description generation. If you do choose to automate, be sure you can review and override whatever has been automatically generated, especially for high-demand / high-volume pages. As with our recommendations above, you're still going to want to regularly test your meta descriptions to see if they can be improved.
As we mentioned above, Google can and will overwrite your Meta Descriptions. This isn't always a bad thing, but it also means you're not always entirely aware of what customers are seeing/reading as they arrive at your site. Remember, Google's goal is to deliver the optimal search engine experience. If Google thinks they can deliver a better experience to their customers by selecting alternative text from your page for a specific keyword, then they will do so. Let's consider an eCommerce example:
