E-commerce meta descriptions: how to write them for your categories (and why Google rewrites them)

The meta description is the most misunderstood tag in e-commerce SEO. Some teams fill it in carefully, hoping to win rankings, which it does not do. Others ignore it because it "does not count", even though it decides part of the clicks. On an e-commerce site, where every click to a category is worth money, both mistakes are expensive.

What the meta description does (and does not do)

Google is clear on this point: the meta description tag is not used for ranking. It will not move you up a single position.

It serves another purpose: suggesting to Google the text it displays under your title in the results. This text, the snippet, is the second thing users read after the title. A snippet that echoes their words and describes the offer precisely improves the click-through rate. And more clicks at the same position means more traffic for the same ranking.

That is why the meta description matters most on pages that already rank: your main categories, your facets that rank on the first page. On those pages, a few points of click-through rate represent hundreds of visits per month.

Google rewrites it often

Ahrefs analyzed 192,656 pages and found that Google rewrote the meta description in 62.78% of cases. The rate rises to 65.6% on long-tail queries and falls to 59.7% on high-volume queries. A quarter of the well-ranking pages did not even have a meta description.

The reason is simple: Google looks for the snippet that best answers each query. A single category ranks for dozens of different queries, and Google adapts the snippet to each one. On your main query, however, a well-written meta description stands a good chance of being kept.

Three situations sharply increase the risk of a rewrite:

• the meta description is missing, and Google takes a passage from the page, often a chunk of menu or filter;
• it is identical across many pages, typical of automatic templates ("Discover our selection of {category} at the best price");
• it does not match what the page contains, or it is stuffed with keywords.

The structure of a good category meta description

On a category page, an effective meta description fits in two sentences and answers three questions:

1. Am I in the right place? Start with the main query, exactly as it is typed.
2. What will I find? Describe the offer concretely: number of models, materials, brands, price ranges, available sizes.
3. Why buy from you? A verifiable argument: delivery, returns, manufacturing, advice, customer reviews.

Aim for about 150 characters. Google truncates according to screen width: what matters is that the decisive information comes first.

Before and after examples

"160x200 fitted sheet"

The original version could appear on any category of the site. The new one echoes the size being searched, answers the question of mattress depth and gives two concrete reasons to click.

"cordless stick vacuum"

Repeating the keyword is pointless: Google already bolds the query words present in the snippet. Brands, battery life and uses are what buyers want to compare.

The facet case

An indexed facet targets a more specific query than its parent category: "160x200 linen fitted sheet", "cordless stick vacuum for pet hair". Its meta description must reflect that precision:

• echo the facet's attributes (material, color, size, brand);
• say what characterizes this selection, not the whole category;
• avoid duplication with the parent category and neighboring facets.

This is precisely where automatic templates fail: a single formula applied to 500 facets produces 500 near-identical snippets, which Google will replace with what it finds on the page. To find out which facets deserve indexing, see our guide to facets.

Mistakes to avoid

• Leaving the field empty: Google will pick a snippet for you, often an unappealing one.
• Using the same text on every category, or a barely customized template.
• Repeating the keyword several times: it is useless for ranking and hurts readability.
• Promising what the page cannot deliver (an expired promotion, a fake "from" price): disappointment is paid for in bounce rate.
• Starting with the brand or an empty formula ("Welcome to...", "Discover..."): the first words are the most read.

Measuring the effect

As with the title, work in batches of comparable pages and track in Google Search Console the click-through rate of the modified pages, at comparable position, over four to six weeks. Also check in the results, on the main query, that Google is indeed displaying your new meta description.

The rules unblind applies to every meta description

Writing a good meta description requires knowing the real offer of the page: its brands, materials, prices, sizes. That is what makes the exercise long to do by hand and doomed with automatic templates. unblind analyzes the content of every category and every facet before writing its meta description, then has it reviewed against precise rules:

• controlled length, around 150 characters;
• a clear discovery promise on a category: what users will find, not a list of stacked technical criteria;
• no orphan call to action, such as a "Discover." added at the end of a sentence to fill the space;
• no interchangeable formula ("for your comfort", "suited to your needs") instead of a real positioning, a concrete assortment or a real service;
• no criterion applied to product families that do not share it;
• services only if they are real: delivery, returns or advice appear in the meta description only if they are confirmed on the site.

The reviewer does not rewrite for a mere style preference: it intervenes on precise flaws, which avoids degrading a good meta description. It is written at the same time as the title, the H1 and the SEO copy of the page, so that they all tell the same story.
