Which of the following is a best practice for title tags?

Title tags should be completely unique for each page to help search engines understand the specific content and purpose of that page. Duplicate title tags can confuse search engines and dilute the ranking potential of individual pages. While including your brand name is often recommended, it's not a strict requirement for every title tag, especially for internal pages where the focus is on the content. Title tags should generally be concise, ideally between 50-60 characters, not 100-125, to avoid truncation in search results. Stuffing title tags with too many keywords (keyword stuffing) is a black-hat SEO practice that can negatively impact rankings and user experience.
