Title Tag Best Practices for 2025
Pixel Width Over Character Count
Google measures by pixels, not characters. Wide letters like W, M, and O take more space than narrow ones like i, l, and t. Always test with a pixel counter.
Front-Load Important Keywords
Place your most important keywords and brand within the first 475 pixels (mobile-safe zone). This ensures they display on all devices.
Use Effective Delimiters
Use pipe (|) or hyphen (-) to separate elements. Format: Primary Keyword - Secondary Keyword | Brand Name. Pipes are more space-efficient.
Account for Keyword Bolding
Bolded keywords add ~15-20% more pixels. Leave buffer room to prevent truncation when your keywords match search queries.
Understanding Google Title Rewriting
Why Google Rewrites Titles:
- Title doesn't match page content
- Keyword stuffing or over-optimization
- Title exceeds pixel width limits
- Missing brand name or unclear branding
- Too generic or not descriptive enough
- Better text found in H1 or page content
How to Prevent Rewriting:
- Make titles match your H1 and page content
- Stay within pixel limits for your target device
- Include your brand name naturally
- Be descriptive and specific, not generic
- Avoid keyword stuffing and repetition
- Write for users first, search engines second

Frequently Asked Questions
Everything you need to know about SERP title pixel counting and optimization in 2025.
What is a SERP title pixel counter and why is it important in 2025?
A SERP title pixel counter measures the exact pixel width of your title tag as it appears in Google search results. In 2025, Google measures titles by pixel width (not character count) with limits of 600px on desktop and 500px on mobile. This tool helps you create titles that display fully without truncation, improving click-through rates and user experience.
How many pixels can a title tag be before Google truncates it?
Google displays titles up to 600 pixels on desktop and 500 pixels on mobile in 2025. However, truncation often starts around 535px on desktop and 475px on mobile in practice. Different characters have different widths (W is wider than i), so pixel measurement is more accurate than character counting. Bolded keywords also increase pixel width.
How do I optimize my title tag for both desktop and mobile in 2025?
Front-load your most important keywords and brand information within the first 475 pixels (mobile-safe zone). Use this tool to test on both devices. Keep titles between 50-60 characters as a guideline, but prioritize pixel width. Use delimiters (| or -) to separate sections, and avoid ALL CAPS which increases pixel width significantly.
Why does keyword bolding matter for title tag length?
When your title tag contains keywords that match a user's search query, Google bolds those keywords in the search results. Bold text takes up more pixels than regular text, potentially causing truncation even if your title fits within limits normally. Use the "Simulate Keyword Bolding" feature to see how your title performs when keywords are matched.
What are the best delimiters to use in title tags?
The most effective delimiters are the pipe (|) and hyphen (-). The pipe is more space-efficient and modern, while hyphens are traditional. Avoid using multiple delimiters or creative alternatives like » or :: which add unnecessary pixels. Format: Primary Keyword - Secondary Keyword | Brand Name.
Does Google rewrite title tags and how can I prevent it?
Yes, Google rewrites approximately 60% of title tags to better match search queries or improve relevance. To reduce rewriting: match your title to page content, avoid keyword stuffing, keep titles under pixel limits, include your brand name, and make titles descriptive and accurate. Google is less likely to rewrite well-crafted, relevant titles.
