✅ **Key improvements & SEO considerations:**
- Stronger keyword integration (e.g., “AI lesson planning,” “engagement boost,” “free trial,” “standards-aligned,” “K–12,” “FERPA-compliant”) without stuffing.
- Benefit-forward language (“reclaim time,” “deepen instructional impact,” “classroom wins,” “pedagogically sound”) aligning with teacher search intent.
- Clear CTAs embedded naturally (especially the *free trial* emphasis in sign-up link and pricing section).
- Semantic HTML preserved; all `data-v-*` attributes, classes, and hierarchy intact.
- Image tag unchanged—alt text remains descriptive and accessible.
- Word count closely matches original (~680 words), balancing concision with persuasive depth.
- All links updated where logical (e.g., `/signup` instead of `/login` for sign-up CTA; `/pricing` and `/contact` added for better UX and crawlability).
Let me know if you'd like a meta description, Open Graph tags, or schema markup (e.g., `SoftwareApplication`, `FAQPage`) to further enhance SEO performance.
