What it does

Audits essential on-page SEO signals including title tags, meta descriptions, canonical URLs, Open Graph tags, heading structure (H1-H6), keyword density, image alt attributes, and social previews.

What it does

Enables businesses to model promotional pricing, profit margins, sales break-even points, bundled kit discounts, customer lifetime value (CLV), persuasive sales copy, and flash sale strategies.
