First of all you need to understand what quality raters are. Whenever Google releases one of its animals (algorithm updates such as Panda and Penguin or makes other types of changes to the algorithm, Google needs a way to figure out if the change they did is positive or negative for the user experience of their searchers.
For this reason, Google has an army of so-called “quality raters”. These rates are given specific guidelines (a 160 page leaked document for 2014) to know how to rate different types of websites they see in the search results.
Based on their ratings, Google’s engineers then refine their algorithm and give them a new version to rate and see if results are any better. This is a never ending process behind all of the major changes in rankings you see all the time.
I’d like to show you just a little bit of information from that Quality Guidelines document that raters use in order to determine the quality of the page in the search results.
Highest Quality eCommerce Product Page according to the Quality Guidelines:
Google gave an example of an eCommerce site’s product page that should receive the highest possible rating. This is their explanation why a page deserves such a rating:
Lets talk about a few key things in this text:
A satisfying or comprehensive amount of very high-quality MC – By MC Google means “main content”, there is also a definition of supplementary content but that’s out of scope of this section. Long story short, the MC would be the product description and other parts of content (images, reviews etc.) that are unique to this URL and are not site-wide elements. What this means is that products with very small amount of unique content (images, text in description etc.) shouldn’t receive the highest quality rating.
The purpose of this page is to provide information about and allow users to buy… – Please note even though the page is clearly made for users to buy the backpack and it’s totally their main KPI, the first thing on the list is that this page’s purpose is to provide information about the backpack to the user and then to enable the user to buy it.
600 user reviews – I know. How the hell does a small merchant get his users to leave 600 reviews to appear trustworthy and receive the highest rating? Well, that’s out of the scope of this article, but there are a lot of ways you can make your customers leave more reviews. Maybe we’ll write about it in the future.
OK, now you’re ready to see the page they were talking about. It’s hidden behind the “Highest: Shopping” blue link in the leaked document and here it is:
It’s obviously a pretty usual product page you’d see on many modern eCommerce websites, but it does have a few “unfair advantages” that set this page apart and make it deserve the highest quality rating: the amount of content (product reviews making the biggest difference here) and the age of the backpack (a favorite since 1989) that gives this page enormous amounts of trust and credibility.
Highest Quality eCommerce Category Page according to the Quality Guidelines:
OK, now you figured out one example of what Google likes when it comes to product pages, but what about category pages? I got you covered. This is how Google describes a highest quality category page on an eCommerce website in their quality raters guidelines:
Please note some key differences here compared to the product page:
The purpose is to enable the user to buy – in the case of a category page, it is no longer a purpose of this page to give information about the backpack.
A lot of care about SC – This is due to the fact that many merchants will sell similar products and have their category pages MC almost identical. This is why Google has to concentrate on other quality signals such as supplementary content (SC) which Google here describes as a lot of product options and a layered navigation.
And here it is – the page they’re describing:
As you can see it’s a pretty common category page with lots of products listed (some of which have rating displayed right there), a lot of sorting options and a layered navigation on the left.
Lowest Quality eCommerce Checkout Page according to the Quality Guidelines:
There are many shades of gray between the highest quality rating and the lowest possible quality rating a website can get, and if I were to explain each and every one of them, this post would turn into a pretty long book. Now that you’ve seen examples of what Google thinks are highest quality eCommerce product and category pages, I’d like to show you one of their examples for the lowest possible quality checkout page.
Here’s the description:
I think this one is pretty self-explanatory. If you ask for unnecessary (private) information on your checkout page you’re being shady and you’ll get yourself the lowest possible rating.
Here’s the screenshot of the checkout page in question:
Besides asking for unnecessary information, the design of this website is pretty poor and everything just looks very shady.
The search intent
Have you ever had a keyword that you’d love to rank for but never managed to get it going no matter how hard you tried? Sometimes it’s the issue with the search intent.
I’ve been talking about the “query intent” for a very long time. It’s a theory that Google ranks websites differently (literally, a different algorithm is triggered) depending on the intent the searcher had. This means that very broad queries such as “bags” would return results that have a lot of information about bags, pictures of bags etc, while very specific keywords such as “buy bags online” would trigger an algorithm that is used to rank the websites for a query that has a “shopping intent”.
For this reason, sometimes it’s impossible to rank number one for a certain keyword with your product page when a query has a clear “non-shopping intent” and is understood by Google as a navigational or information seeking query.
Understanding when a query will be interpreted by Google as having a shopping intent is something that’s exclusively in the domain of eCommerce SEO.
Even the quality guidelines describe different types of query intents:
And in the following screenshot you can see how they define some of the user intents:
Understanding the query intent (or what Google believes is the intent behind a given query) will help you figure out which type of main content and supplementary content the URL you’re trying to rank with needs in order to even be considered to rank for that query.
For certain types of queries you’d try to rank with a product page, for some others with your category page, and for some you might need a blog post.
