Title tag length and best practices

Google truncates displayed titles by pixel width, roughly 580 to 600 pixels on desktop, which corresponds to about 55 to 65 characters depending on letter widths. Mobile shows a similar range over two lines. There is no length limit for what Google reads; the limit is for what it displays. A title of 70 characters is not penalised, but its ending may be cut, so the words that matter must come first.

Titles under about 30 characters waste the opportunity to describe the page and are more likely to be rewritten with additional context.

Since 2021 Google generates the displayed title from several signals, including the title tag, the H1, other prominent headings, and anchor text of links to the page. It replaces your title when it is too long, when it is boilerplate repeated across pages, when it is stuffed with keywords, when it does not match the page content, or when the H1 describes the page better. Google reports that the title tag is still used most of the time, so the goal is to write a title Google has no reason to replace.

Guides and how-tos: the task first, then a qualifier, then brand. Comparison pages: "X vs Y: the difference for [audience]". Alternatives pages: "[Competitor] alternatives for [use case]". Answer pages: the question itself, lightly trimmed, works as both title and H1 and is what AI assistants match on. Product and feature pages: capability first, product name last. Keep separators simple; a colon or a pipe is fine.

At scale the risk is sameness. A template that produces "Best [X] tools for [Y]" a hundred times yields a hundred near-identical titles that Google rewrites and searchers cannot distinguish. Build the template so the variable part comes first and carries the meaning, vary the pattern across page types, and run a uniqueness check before publishing. SerionFlow's quality gate requires unique metadata on generated pages for this reason; other platforms should be checked for the same.

Crawl the site or export from your CMS, then check each title for length in pixels, duplication across the site, presence of the primary query, agreement with the H1, and whether it is being rewritten in search results. Search Console does not show rewrites directly, but comparing the title tag with the displayed title on a sample of queries reveals them. SerionFlow's free title tag checker evaluates a single URL for length, duplication signals, and structure; a crawler handles the site-wide pass.

Title changes affect click-through rate more than position. In Search Console, compare CTR for the page over the four weeks before and after the change, controlling for position. A title that raises CTR at the same position is a win; a title that raises impressions but drops CTR may have broadened the match to the wrong queries. Platforms with a weekly loop, such as SerionFlow's flywheel, flag high-impression low-CTR pages as rewrite candidates automatically.
