I've tested these across multiple client sites, and the correlation between content depth and rankings is undeniable.

A: Based on my experience, 3-6 months for competitive keywords, 1-3 months for low-competition terms. Focus on content quality over speed.

Q: Does image optimization really affect rankings?

A: Absolutely. I've seen 40% traffic increases from image-heavy pages after proper optimization. Google explicitly states images are a ranking factor.
