Why does Google change my title tag?
Google rewrites titles when it believes the original is too long, too short, keyword-stuffed, or does not match the user's search query well. Common triggers: excessive boilerplate (repeating your brand on every page), title too generic (“Home”), or mismatched content. To reduce rewrites, keep titles under 60 characters, make them unique per page, and accurately describe the page content.
How do mobile and desktop SERP snippets differ?
Mobile titles display about 55–60 characters (similar to desktop), but descriptions are shorter at around 120 characters. Mobile results also show more visual elements: favicons appear next to every result, and featured snippets are more prominent. With 60%+ of searches now on mobile, optimizing for the shorter mobile display is critical.
Does meta description affect rankings?
Google confirmed that meta descriptions are not a ranking factor. However, a compelling description increases CTR, and user engagement signals (high CTR, low bounce rate) can indirectly improve rankings over time. Think of the meta description as marketing copy, not an SEO lever.
