Frequently Asked Questions
What is the typical turnaround time for a custom website?
A conversion-focused business website or landing page is typically delivered within 7 to 10 business days. Custom web applications, booking calculators, and portal integrations are completed in 14 to 21 business days with live staging preview links throughout development.
Do I get 100% full ownership of the source code?
Yes, 100% guaranteed. Upon final milestone settlement, TechCognita transfers complete intellectual property rights, Git repositories, database configurations, and deployment scripts to you. You own every line of code with zero recurring vendor lock-in or theme licensing fees.
Why do you build on React instead of traditional WordPress?
Traditional WordPress websites rely on heavy themes and plugins that slow page loads down to 4–6 seconds, hurting Google Ads Quality Scores and increasing cost-per-click. Our custom React and TypeScript applications load in under 1.2 seconds, deliver 95+ PageSpeed scores, and convert ad clicks into confirmed leads at significantly higher rates.
Can you integrate instant WhatsApp lead generation into my website?
Yes. We specialize in automated WhatsApp lead routing. Visitors can calculate prices, request quotes, or ask questions on your website, and their prefilled request is delivered directly to your WhatsApp desk in under 30 seconds.
How do your websites help improve Google Ads performance?
Google Ads rewards landing pages that load fast, offer relevant content, and provide frictionless mobile experiences with higher Quality Scores (8/10 to 10/10). This directly decreases your cost-per-click (CPC) and lowers your customer acquisition cost (CAC).
