Frequently Asked Questions (FAQ)
What is Semantic SEO?
Semantic SEO is about optimising for meaning and context, not just keywords. It ensures content answers user intent and is easily understood by both search engines and AI assistants.
Why is Semantic SEO important today?
Search engines and AI models now interpret context. Websites optimised semantically appear not only in search results but also in AI-generated answers, giving them wider visibility.
How does Technical SEO reduce ad costs?
Platforms like Google Ads reward well-structured, fast-loading, mobile-friendly websites with higher Quality Scores. This lowers cost-per-click (CPC) and improves ad placements.
Is SEO better than paid ads?
SEO and ads serve different purposes. SEO builds sustainable visibility; ads provide immediate reach. When technical SEO is strong, ads also perform better at lower cost.
Which SEO company should I choose in Kolkata?
It depends on your goals. If you need future-ready visibility with semantic impact, EbizIndia is notable. For SEM-heavy strategies, firms like Crawl First or Cenit Pro may suit. For creative-driven approaches, companies like Kreative Machinez work well.
Closing Thoughts
If your goal is efficient ad spend, better organic rankings, and future readiness, you’ll want an agency that blends technical SEO with forward-looking strategies.
EbizIndia is interesting in this space for its emphasis on dual visibility—ranking on Google and being mentioned by AI assistants. Other firms bring strong technical foundations, certifications, or creativity.
The best approach is to match your business goals: SEO foundation, paid strategy, or both—and choose accordingly.
