Meta Description

A meta description is the short summary tag in a page's HTML that a search engine may display beneath its result; it is not a direct ranking factor, but a clear, relevant description can improve click-through rate, and Google often rewrites it to better match the searcher's query.

You set a meta description with a meta tag in the page head, and the typical visible length runs to roughly 150 to 160 characters on desktop, often less on mobile, before it is truncated with an ellipsis. The goal is not to pack in keywords but to write an honest, specific summary that tells a searcher what the page delivers and why it answers their query. A description that reads like a plain answer to the exact thing the person searched tends to earn more clicks than one padded with repeated terms. Matched query words are bolded in the snippet, so phrasing the description in the searcher's own language gives the listing more visual weight on the results page.

The honest nuance is that you do not fully control what appears. Google frequently rewrites or replaces your tag with a snippet pulled from the page body when it judges that to be a better match for a specific query, so the same page can show different descriptions for different searches. Treat the tag as a strong suggestion rather than a guarantee, and make sure the on-page copy it might draw from is just as clear, because that body text is what gets surfaced when your tag is set aside.

Consider a Shopify store selling merino base layers. The default theme often outputs the same generic description on every collection, so the merino t-shirt page and the merino leggings page compete in search with identical snippets. Rewriting the t-shirt collection description to something concrete, such as a line noting lightweight merino tees in five colours with free returns and next-day dispatch, gives the searcher a reason to choose that result over a rival listing. Each collection and product should carry its own description, written once and reviewed when the range or the offer changes.

There is a quieter benefit for AI search and answer engines. Tools like ChatGPT, Perplexity, and Google AI Overviews lean on the same clean, structured summaries that crawlers index, and a precise description helps a model understand what a page is about before it decides whether to cite or paraphrase it. The description will rarely be quoted word for word, but writing pages so the core claim is stated plainly, in the tag and in the opening body copy, makes a store easier to summarise correctly rather than guessed at.

Because it shapes clicks rather than rank, the meta description sits next to the title tag as part of how a result presents itself in the listing. Write it per page, avoid duplicates across the site, keep the most important words near the front so the value survives truncation, and resist the urge to mislead, since a snippet that overpromises tends to raise the click and then lose the visitor on arrival.
