How long does SEO take to work?

E-commerce SEO typically takes 4-6 months to see significant results. However, some pages (especially long-tail keywords) can start ranking in 2-4 weeks. SEO is a long-term investment that compounds over time.

Can I do SEO myself or should I hire someone?

You can absolutely do SEO yourself if you follow a structured approach. Start with technical fundamentals, optimize your product pages, and build a consistent content publishing schedule. As you grow, consider hiring an agency or freelancer for advanced link building and technical audits.

What is the single most important SEO factor for e-commerce?

Page speed and mobile optimization are the foundation. If your site is slow or doesn't work well on mobile, nothing else matters. Google's Core Web Vitals are ranking signals. After that, focus on unique, high-quality product content and a smart internal linking structure.

How do I avoid duplicate content issues?

Manufacturer product descriptions are the #1 cause of duplicate content in e-commerce. Always write original descriptions. Use canonical tags for product variations (same product, different color). For faceted navigation, either make filters AJAX-based (no new URLs) or add noindex tags to filter pages.

Should I index all my product pages?

Not necessarily. Thin content pages (no description, low quality) should be noindexed. Out-of-stock products should be either noindexed or redirected until restocked. Focus indexation on pages with 300+ words of unique content and genuine search potential.
