FAQ: Frequently Asked Questions
What is Google's title limit?
Google uses pixel width, not character count. 55-60 chars typically fits.
How many words should H2 be?
For featured snippets, H2s of 47-75 words perform best. Too short misses context; too long gets truncated.
What is optimal blog length?
Long-form (2000+ words) ranks best for competitive keywords. Short posts can rank if they answer thoroughly.
