The meta description lives in the HTML code of every page, specifically inside the <head> tag. You won't see it when viewing the actual webpage in your browser. Instead, it shows up in Google search results as the snippet of text below your page title and URL. To find it, right-click any webpage, select "View Page Source" or "Inspect," and look for a line that starts with <meta name="description" content="...">. Most content management systems let you edit this without touching code. In WordPress, plugins like Yoast or Rank Math put the meta description field right in your post editor. Shopify has it under "Search engine listing preview" for each product or page. Wix and Squarespace bury it in page settings under SEO or advanced options. The meta description doesn't directly affect rankings, but it influences click-through rate. Google pulls it into search results about 63–68% of the time in our testing—the rest of the time, Google rewrites it by extracting sentences from your page content that better match the searcher's query. We write meta descriptions at 140–155 characters to avoid truncation on mobile. Longer ones get cut off with an ellipsis, which looks sloppy. Every page on your site should have a unique meta description. Duplicate or missing ones waste an opportunity to control your first impression in search results. At Ottawa SEO, we audit meta descriptions during technical SEO reviews because many clients either leave them blank or auto-generate garbage like "Home | Company Name." A good meta description previews the page content, includes your primary keyword naturally, and gives searchers a reason to click. Think of it as ad copy that costs nothing to test. If your click-through rate is low despite ranking on page one, rewriting meta descriptions often delivers a measurable lift within two weeks.
