Technical SEO & CRO
Core Web Vitals, structured data, internal linking, and conversion experiments that move the needle.

01 What it is
What this service is
Technical SEO is the engineering side of search — Core Web Vitals, crawl budget, structured data, hreflang, canonical tags, sitemap, robots.txt, AI crawler discoverability. CRO (conversion rate optimisation) is the practice of running experiments on the converting surfaces of the site to lift the percentage of visitors who become customers.
Devinsta does both as one discipline — because the same speed and clarity wins both at once.
02 What it's for
What it's for
You need technical SEO when traffic is flat or declining despite content investment, when Lighthouse scores are damaging rankings, when Google Search Console shows crawl errors or coverage drops, or when you're expanding into new regions and need hreflang done properly.
You need CRO when traffic is fine but conversion is the bottleneck — when the funnel is leaking somewhere between landing page and signup.
03 How to use it
How to engage devinsta
We start with a technical audit — site crawl with Sitebulb / Screaming Frog, Core Web Vitals from real user data, structured data validation, AI crawler accessibility. For CRO we layer in a heuristic review and quantitative funnel analysis. Deliverable: a prioritised remediation roadmap and a 90-day experiment plan.
04 How to deploy
How we deploy it
Technical SEO fixes ship as code changes — sitemap and robots.txt updates, schema.org JSON-LD on every page, hreflang in head, canonical tags, redirect cleanup, Core Web Vitals tuning. CRO experiments deploy via your existing A/B platform (VWO, Optimizely, Convert) or via a feature-flag pattern in code (Statsig, LaunchDarkly).
We report weekly on rankings, CWV, crawl coverage, and experiment results.

FAQ
Common questions
Can you help us rank in multiple countries?
Yes — hreflang done properly, regional content variants, country-specific structured data, and either country-coded subdirectories or ccTLDs. We've shipped multi-region setups across US, UK, EU, LATAM, and APAC.
What about AI search engines like ChatGPT and Perplexity?
We optimise for AI crawlers explicitly — robots.txt that allows GPTBot, ClaudeBot, PerplexityBot, Google-Extended; semantic HTML; FAQPage schema; clear citations. Many of our clients see meaningful traffic from AI answer engines now.
How fast does CRO move the needle?
Variable. A good CRO programme delivers 5–25% conversion lift in the first quarter through a handful of high-leverage tests. We're transparent about the math: 80% of CRO tests are flat or negative; the winners pay for everything.
