How I got here
I am from New Delhi, India. I started building and ranking websites while still in school, and turned it into a craft: WordPress, technical SEO, content, and the systems that hold a site together. My first project did well enough to be acquired, which told me this was worth doing properly.
In 2016 I started TheGuideX as a blog for beginners, and built it into a known SEO and WordPress resource. In 2019 I turned down an acquisition offer for it and kept building. From 2018 to 2024 I also ran TheWPX, a second blog about WordPress.
Along the way I shipped products: PC Builder, Carousify, Grip AI, and Acadise, plus a WordPress plugin, User IP and Location, that runs on more than 3,000 live sites. Shipping is the fastest way to learn how search and the web actually behave.
In 2024 TheGuideX became an SEO and web consultancy, and the name describes how I work. A guide has walked the ground first. X marks the spot where the real problem sits. The notes in the insights come from that work, not from theory.
Work you can check
My WordPress plugin, User IP and Location, is public on WordPress.org with more than 3,000 active installs. The code for my open-source work is on GitHub.
I hold certificates in Technical SEO and AI Search Essentials from Semrush, Fundamentals of Digital Marketing from Google, SEO Link Building from LinkedIn Learning, and SQL from the University of Michigan.
When I put a tool in a roundup, I say how deeply I checked it: used in real work, signed up and tried, or checked from the vendor's own pages. Nobody pays for a position. The full method is on how we test and rank tools.
What I work on
Technical & On-Page SEO
Crawl, indexation, canonicalization, schema, architecture, and Core Web Vitals.
Generative Engine Optimization
Entity clarity and structured data so AI search can understand and cite a brand.
WordPress Development
Builds, speed and security hardening, and WordPress-to-static migrations.
Link Building & Content
Audience-first links and content that survive Google core updates.
Also building
LinkedIn growth & carousel tool
SEO services & SERP tool
School discovery & admin platform
PC compatibility checker
Self-hostable AI agent platform
WordPress plugin · 3,000+ active installs
How I think about the work
Most indexing problems are canonicalization problems in disguise. Before I touch crawl budget or the sitemap, I find the duplicate cluster: the URLs quietly fighting to be the canonical one. That is almost always the real bug.
Site speed is an engineering problem, not a marketing one. You do not fix Core Web Vitals from a plugin settings page. It lives in the render path, the database queries and the JavaScript, so I keep that work in my own hands.
A link is only worth building if it would still make sense with Google switched off. Links built for a real audience survive core updates. Links built only to move a ranking are the ones the next update quietly takes back.
I do not treat AI search as a separate discipline. A citation in ChatGPT or AI Overviews is won the same way a featured snippet always was: a clear answer, and authority Google can already verify. New surface, old fundamentals.
