Answer
What are the best website templates for SEO?
The best website templates for SEO ship with clean semantic HTML, single H1 per page, JSON-LD schema, sitemap-ready URL structure, Core Web Vitals 90+ on mobile, and lazy-loaded WebP images. SiteFyd premium templates ship with all of these baked in.
What to verify before buying
Run the demo through PageSpeed Insights, view-source to check for JSON-LD and single H1, check robots.txt and sitemap.xml are present, and confirm the template ships responsive WebP images with srcset.
Why most marketplace templates fail this check
Marketplaces optimize for design previews, not SEO foundations. Common failures: multiple H1s, missing schema, JPGs instead of WebP, no sitemap, and CLS scores above 0.25 because hero images load without dimensions.
