"Your" Versus "You're"
Both are capitalized in titles. "Your" is a possessive ("Your Guide to SEO"), and "you're" is a contraction of "you are" ("You're Doing It Wrong"). Capitalization does not change between them; only the spelling does.

"Your" in Sentence Case
APA reference lists, many news sites, and most UI text use sentence case instead of title case. There, only the first word and proper nouns get capitals, so "your" is lowercase unless it starts the title: "How to grow your blog." Pick one of the two styles for a whole set of headings rather than mixing them.
