Most Bangalore product companies build their marketing sites on React, Next.js or a headless CMS. That is great for developers and often terrible for rankings, because what Google indexes is not always what users see.
Check the rendered HTML, not the source
Open Search Console, inspect a key URL and view the rendered HTML. If your headings, body copy or internal links are missing, Google is not seeing them either. Server-side rendering or static generation for marketing pages fixes most of this.
Watch for soft 404s and blocked resources
Client-side routes that return 200 for pages that do not exist, and JavaScript bundles blocked in robots.txt, both waste crawl budget and confuse indexing.
Keep one URL per page
Trailing slashes, uppercase paths, UTM parameters and staging subdomains create duplicates. Pick one version, redirect the rest and set self-referencing canonicals.
Speed still matters
Interaction to Next Paint (INP) replaced FID as a Core Web Vital. Heavy hydration on marketing pages is the usual culprit; defer non-critical scripts and split bundles.
Structured data for AI search
Add Organization, Product/SoftwareApplication and FAQ schema so AI engines can describe your product precisely.
