Technical SEO that gives your content a fair chance
Great content can't rank if search engines struggle to crawl, render or trust your site. Technical SEO removes those barriers with developer-level fixes, not just a report.
Overview
Why Technical SEO matters
Technical problems are often invisible to site owners: a stray noindex tag, a canonical pointing to the wrong page, redirect chains after a migration, or a JavaScript-heavy template that hides content from crawlers. Each one quietly limits how much of your site can rank.
Because Raj also builds websites, fixes are specified precisely and can be implemented directly on WordPress, Shopify or custom code, rather than handed over as vague recommendations.
Who it's for
Large or growing sites
Sites with hundreds or thousands of URLs where crawl efficiency and duplication matter.

Slow sites
Websites failing Core Web Vitals on mobile.

FAQ
Technical SEO: common questions
What are Core Web Vitals?
They're Google's user-experience metrics: Largest Contentful Paint (loading), Interaction to Next Paint (responsiveness) and Cumulative Layout Shift (visual stability). They're one of many ranking signals and also affect conversions.
Do I need technical SEO if my site is small?
Small sites usually need less, but a single misconfigured setting such as a noindex tag can still remove pages from Google. A quick audit tells you whether there's anything worth fixing.
Can you work on Shopify's technical limitations?
Yes. Shopify has fixed URL patterns and some duplication by design; there are well-established ways to manage canonicals, collections and apps to limit the impact.
Will technical fixes break my site?
Changes are tested on staging where possible and rolled out carefully, with redirects and backups in place.
