Common questions

Questions marketing leads ask.

Why Next.js instead of WordPress?

WordPress with page builders typically scores 30-50 on Lighthouse Performance against mobile testing — failing Google's Core Web Vitals thresholds. Next.js with server-side rendering hits 90+ on Performance and 100 on SEO when built correctly, which directly affects search ranking and conversion rate. WordPress still makes sense for content-heavy blogs that need editor friendliness with no perf constraints; for marketing sites and B2B portals where speed and SEO matter, Next.js wins.

Can the website integrate with our existing CRM / ERP?

Yes. We have shipped production integrations with HubSpot, Zoho, Salesforce, Microsoft Dynamics, Tally ERP, SAP B1, Razorpay, Stripe, Mailchimp, ActiveCampaign, WhatsApp Business API, and SMS gateways. Custom integrations are scoped based on the third-party's API availability — most modern systems ship REST or webhook interfaces we can adapt.

Do you offer ongoing SEO and content support?

Yes — through our [Digital Marketing service](/services/digital-marketing). Post-launch SEO support typically covers monthly Search Console reviews, content briefs for new pages, technical SEO audits, and structured-data additions. Pricing is separate from the build and starts at Rs 35,000 per month.

Will the site be mobile-responsive?

Yes — mobile-first responsive design is the default. We test on a 12-device matrix covering low-end Android (Redmi 9A, Galaxy M04), mid-tier (Note 12, Galaxy A24), high-end (Pixel 8, Galaxy S24), and three iPhone generations. Every page is verified on real devices, not just emulators.

Can we manage content ourselves after launch?

Yes — most builds include a headless CMS (Sanity, Strapi, Payload, or WordPress in headless mode) so your team can edit page copy, blog posts, and images without developer involvement. The CMS sits behind authentication; content edits trigger a build and re-deploy automatically. Optional Markdown / Git-based workflow for technical teams that prefer code-managed content.
