HOW WE WORK

Technical SEO that’s focused, flexible, and built to perform

From audits to implementation, everything is handled with care and precision. Expect clear recommendations, clean fixes, and measurable improvements – whether you're looking to improve speed, pass Core Web Vitals, or resolve indexation issues holding your site back.

Performance optimization built for real results

Speed isn’t just a nice-to-have – it’s a ranking factor. Technical SEO work can include asset minification, render-blocking script fixes, server-level tweaks, image optimization, and other performance enhancements aimed at improving load times and Core Web Vitals scores. Whether you’re struggling to pass PageSpeed Insights or just want things running faster, we’ll help you get there.

Every site is different, so recommendations are tailored to your setup, platform, and goals. You’ll get clear actions, implemented cleanly, with performance that lasts beyond a one-time fix.

Technical audits that go beyond checklists

Automated tools only catch so much. Our audits go deeper – looking at site structure, code output, accessibility, schema markup, crawl directives, and how your front-end build impacts search visibility. We flag what matters, explain why it matters, and show you exactly what to do about it.

You can handle implementation on your side – or ask us to take care of it. Either way, you’ll walk away with a prioritized, actionable plan focused on the technical issues most likely to move the needle.

Clean, crawlable code that supports visibility

Search engines reward clarity. We focus on semantic HTML, proper heading structure, meaningful alt text and a codebase that’s easy to index and understand. Whether we’re building your site or optimizing an existing one, technical SEO improvements are designed to strengthen how your site is read and ranked.

We also review sitemap structure, canonicalization and robots directives so only the right content is crawled, and add structured data (JSON-LD schema) that tells Google and AI assistants exactly what each page is about – the foundation for our AI search visibility (AEO) work.

Implementation support that fits your workflow

You don’t need to manage multiple vendors or decipher unclear reports. We’ll walk you through the fixes, implement updates directly, or collaborate with your internal team – whatever works best for your setup. Communication is clear, timelines are realistic, and all changes are made carefully, without disrupting your live site.

Whether you’re chasing Core Web Vitals compliance, fixing a drop in rankings, or just cleaning up messy code, technical SEO work is handled with precision, transparency, and zero guesswork.

I’ve worked with Viktor from Reliable for almost a decade on multiple projects including at least two re-designs of a WordPress site that was the home base for a business I ended up selling. They have been a trusted partner for small and large issues and I am constantly impressed with the turn around time and problem solving ability. Highly recommend for any WordPress project.

We had such a great experience with the team at Reliable. They worked efficiently, communicated clearly and provided with a great website. I thoroughly enjoyed working with the whole team. April was enthusiastic and quick to communicate. David understood our goals and deadlines. They both set the realistic expectations and delivered as promised.

TECHNICAL SEO FAQ

Frequently asked questions about our technical SEO services

Common questions about working with our technical SEO team. Don't see your question here? Check our FAQ page or get in touch.

Our technical SEO services cover the parts of SEO that live in your site’s code and setup: Core Web Vitals and page speed, crawling and indexing (robots.txt, XML sitemaps, canonical tags, redirects), heading structure, structured data, image optimization and mobile performance. You can have us audit only, or audit and implement the fixes ourselves – on WordPress, Webflow and custom builds, whether or not we built the site.

Because most Core Web Vitals problems are code problems. A slow Largest Contentful Paint, laggy Interaction to Next Paint or shifting layout usually comes from render-blocking scripts, heavy themes and plugins, oversized images and third-party tags. Many SEO agencies can report these issues; our development team fixes them in your theme and templates, then re-tests with PageSpeed Insights and real-visitor Chrome data to confirm the improvement. More on our WordPress performance optimization page.

Yes. We add and repair schema markup (JSON-LD) for your organization, services, articles, FAQs and products, and validate it with Google’s Rich Results Test. We also fix the crawl issues Google Search Console reports – blocked or orphaned pages, redirect chains, duplicate pages without canonicals and sitemap errors – so search engines and AI assistants index the pages you want found.

Yes. Technical SEO work often starts on a site someone else built. We begin with an audit of your setup, explain what we find and why it matters, then make the fixes carefully so nothing on your live site breaks. If you have your own developers, we can hand them a prioritized plan instead.

Technical SEO makes your site fast, crawlable and easy for search engines to understand. AEO (answer engine optimization) builds on that foundation so AI assistants like ChatGPT, Perplexity and Google’s AI Overviews can find, understand and cite your content. Technical SEO is usually a project with periodic rechecks; our AEO services are ongoing optimization with monthly checks.
