Blogger offers two places to set meta descriptions: a blog-wide default and individual post overrides. For the blog-level description, navigate to your Blogger dashboard, click Settings, then scroll to Search preferences. Under Meta tags, enable the search description toggle and enter your default description (maximum 150 characters). This description applies to your homepage and any post that doesn't have its own custom description. For individual posts and pages, the process is simpler but easy to miss. Open any post in the editor, and look for the right sidebar. Under Post Settings, you'll see a Search Description field. Click it and enter a unique description for that specific post. This overrides the blog-wide default and gives you precise control over what appears in search results for that URL. Blogger enforces a strict 150-character limit, which is shorter than Google's typical 155–160 character display window. You'll need to be concise. Front-load your primary keyword and value proposition in the first 120 characters to ensure the most important information shows even if Google truncates further. One limitation: Blogger doesn't let you set meta descriptions in bulk or preview how they'll look in search results. You're working blind unless you manually check Google Search Console or use a SERP preview tool. At Ottawa SEO, when we work with Blogger sites, we typically create a spreadsheet to track which posts have custom descriptions and which are falling back to the default, because Blogger's interface doesn't surface this information clearly. If you're running a content-heavy Blogger site, prioritize custom descriptions for your top 20% of pages by traffic. Those posts drive most of your visits, and a well-crafted description can lift click-through rates by 10–30% compared to auto-generated snippets. For lower-traffic posts, a solid blog-wide default is acceptable, especially if you're managing dozens or hundreds of posts. Google will often rewrite your description anyway if it doesn't match the query, but giving it a strong starting point still matters.
