Technical SEO is the groundwork that lets everything else you do online actually work. You can have great service pages and a strong Google Business Profile, but if Google struggles to crawl your site, loads it slowly or finds three pages competing for the same search, most of that effort goes to waste.
We look at the parts of your website that visitors don’t see but search engines do, fix what’s holding you back, and keep an eye on it so new problems don’t creep in.
What technical SEO covers
- Crawling and indexing. Making sure Google can find and index the pages that matter, and isn’t wasting time on the ones that don’t. That means checking your sitemap, robots settings, canonical tags and any pages accidentally set to noindex.
- Redirects and broken links. When pages move or a site is redesigned, old addresses need to point to the new ones. Without redirects, the rankings those pages built up are lost and visitors land on a 404 page.
- Site speed and Core Web Vitals. Slow pages lose visitors and rank worse, especially on mobile. We look at image sizes, caching, scripts and hosting.
- Mobile performance. Most of your visitors are on a phone, and Google mainly judges your site on its mobile version.
- Duplicate content and cannibalisation. When several pages target the same search, they compete with each other and none of them ranks as well as it should.
- Structured data. Schema markup helps Google, and AI tools, understand your business, your services, your reviews and your location.
- Internal linking. Linking your blog posts and pages to the right service pages so visitors, and Google, can find the pages that bring in enquiries.
- Titles, meta descriptions and headings. Checking that every important page has its own title and description, not a copy of another page’s.
Signs your website has technical SEO problems
- Pages that used to rank have dropped, especially after a redesign or a move to a new website.
- Google Search Console shows lots of pages as “not indexed” or “page not found”.
- Your site feels slow on a phone.
- Several of your pages appear for the same search, but none of them near the top.
- Your service pages get almost no impressions while your homepage does all the work.
These problems are more common than people think, and they rarely fix themselves. When we reviewed our own website, we found old service page addresses that had stopped working after a restructure and several pages competing for “web design Dundalk”. We fixed both. It’s exactly the kind of thing we check on every site we take on. If you want to check your own site first, I’ve written a guide on why a website is not showing up on Google and how to fix each cause.
How we approach technical SEO
- Audit. We go through the site and Google Search Console to see what’s actually happening: what’s indexed, what’s broken, what’s slow and what’s competing with what.
- Prioritise. Not every issue matters equally. We fix the problems that are costing you visibility and enquiries first.
- Fix. Redirects, speed improvements, canonical and indexing fixes, structured data, internal links and page-level fixes.
- Monitor. We keep watching Search Console so new problems are caught early, not months later.
Technical SEO is part of our ongoing SEO services rather than a separate one-off job, because a site that’s fixed once can slip again with every update, new page or plugin. You can see how our SEO pricing works in our guide to how much SEO costs in Ireland.
Frequently asked questions about technical SEO
What’s the difference between technical SEO and on-page SEO?
On-page SEO is about the content on each page: the words, headings and topics. Technical SEO is about how the site works underneath: whether Google can crawl it, how fast it loads, how pages are linked and whether anything is broken. Both matter, and they work best together.
Does a new website need technical SEO?
Yes, and it’s the best time to get it right. A new site built with clean structure, proper redirects from any old site and correct settings from day one avoids problems that are much harder to untangle later.
Can technical problems really affect my rankings?
They can. Pages that return errors, can’t be indexed or compete with each other simply won’t rank as well as they should, no matter how good the content is.
Is technical SEO only for big websites?
No. Small local business sites often have the most straightforward fixes, and those fixes can make a noticeable difference because there’s less competition to begin with.
