Your website might look great. The photos are sharp, the copy is solid, and you’ve got good reviews. But if Google can’t properly read your site, none of that matters.
That’s where technical SEO comes in.
What Technical SEO Actually Means
Most people have heard of SEO. They know it involves getting their website to show up on Google. But technical SEO is a specific part of that puzzle, and it’s the one that business owners most often overlook.
Think of it this way. Content SEO is what you say on your website. Technical SEO is whether Google can actually find, read, and understand what you’ve written. If your site has technical problems, Google may struggle to crawl it properly, miss pages entirely, or rank you lower than you should be.
Technical SEO covers things like page loading speed, mobile compatibility, site security (HTTPS), URL structure, broken links, and whether your pages are set up to be indexed correctly by search engines.
It’s not glamorous. But it’s the foundation.
Why Search Engines Care So Much About It
Google’s job is to give people the best possible answers to their searches. To do that, it sends bots to crawl billions of web pages and figure out what each one is about.
If your site is slow, poorly structured, or full of errors, those bots have a harder time doing their job. Google then either ranks you lower or ignores certain pages altogether.
According to SE Ranking’s 2025 research, around 94% of all web pages receive no traffic from Google whatsoever. That’s not just a content problem. In many cases, it’s a technical one.
On top of that, Google has been using mobile-first indexing since 2024, which means it predominantly crawls and ranks the mobile version of your website. If your site doesn’t work well on a phone, your rankings will suffer on desktop too.
The Most Common Technical Problems Business Websites Have
You’d be surprised how many professional-looking websites have serious technical issues lurking underneath. Here are the ones that come up most often.
Slow page speed. According to SE Ranking, 35% of websites have slow page loading speeds. A site that loads in one second converts three times better than one that takes five. Every extra second costs you visitors and potential customers.
Oversized images. The same research shows 36% of websites have oversized images. Large image files are one of the biggest causes of slow load times, and they’re also one of the easiest things to fix.
Broken pages. Around 36% of websites contain pages that return 4XX errors, meaning a page doesn’t exist or can’t be found. These are bad for users and bad for your rankings. Google takes them seriously.
Missing alt text. Only 26% of websites properly use alt text on their images. Alt text tells search engines what an image shows. Without it, you’re leaving ranking opportunities on the table.
No sitemap or a broken one. Over 15% of websites are missing an XML sitemap entirely. This is the file that tells Google which pages you have and helps it find them quickly.
Poor internal linking. Nearly 70% of websites have pages with no internal links pointing to them. If Google can’t find a page by following your site’s own links, it’s effectively invisible.
How Technical SEO Affects Your Local Search Rankings
For UK businesses that rely on local customers, technical SEO matters even more than most people realise. Your professional SEO strategy needs to start with a technically sound website before anything else can work.
When someone searches for “IT support in Crawley” or “accountant in Guildford”, Google doesn’t just look at your content. It also checks how fast your site loads on mobile, whether your pages are indexable, and how well structured your site is. A competitor with a technically cleaner website will often outrank you, even if your content is better.
Regular website maintenance plays a big part in this. Sites that are updated, monitored, and kept free of errors give Google a consistently positive signal. Neglected sites with broken links, outdated code, and slow load times send the opposite message.
What You Can Check Right Now for Free
You don’t need to be a developer to run a basic technical check on your website. These three free tools give you a solid starting point.
Google Search Console is probably the most useful tool available to any business owner. It shows you which pages Google has indexed, which ones it’s struggling with, and what errors exist on your site. If you haven’t verified your site with Google Search Console, do it first.
Google PageSpeed Insights tests how quickly your site loads on both desktop and mobile. Enter your URL and you’ll get a score out of 100, along with specific suggestions for what to fix. Anything under 50 on mobile is affecting your rankings.
Google’s Mobile-Friendly Test checks whether your site works properly on smartphones. Given that the majority of web traffic now comes from mobile devices, this is not optional.
These checks will show you what’s wrong. The harder part is knowing what to fix first and how to fix it properly.
When to Call in Professional Help
Some technical SEO fixes are quick. Compressing images, fixing broken links, and adding missing alt text don’t require deep technical knowledge and can often be done in a single afternoon.
Other issues are more complex. Problems with your site’s crawl budget, JavaScript rendering, duplicate content, and structured data markup usually need someone who knows what they’re doing. Getting these wrong can make things worse.
If your site was built some time ago or hasn’t had professional attention in a while, a technical audit is a good place to start. A proper audit maps every issue on your site, prioritises what needs fixing, and gives you a clear action plan.
A well-built website is part of the answer too. If your site was built on a shaky technical foundation, no amount of content or link-building will fully compensate for it. That’s why good web design and solid web development go hand in hand with a strong SEO strategy.

Frequently Asked Questions
Is technical SEO different from regular SEO?
Yes. SEO covers everything involved in ranking a website, including content, links, and technical factors. Technical SEO is specifically concerned with the structure and performance of your website, including how easily search engines can find and read your pages. You need both working together to rank well.
Do I need to be technical to manage technical SEO?
You don’t need to be a developer to understand the basics, but fixing technical SEO problems usually requires some level of coding knowledge or access to a professional. Tools like Google Search Console and PageSpeed Insights are free and accessible, but interpreting the results and implementing fixes is where most business owners need help.
How do I know if my website has technical SEO problems?
The quickest way is to run your site through Google Search Console and Google PageSpeed Insights. Both are free. Search Console will show you any pages Google can’t index, and PageSpeed will flag speed and mobile issues. If your site isn’t ranking for keywords you expect to rank for, technical problems are often part of the reason.
Does website speed really affect Google rankings?
Yes, directly. Google uses Core Web Vitals, a set of speed and user experience metrics, as a ranking factor. Sites that load slowly and perform poorly on mobile are ranked lower. Research from SE Ranking shows that a site loading in one second converts three times more than one taking five seconds, so speed affects not just your rankings but also the leads you actually get from them.
How often should I check my website for technical SEO issues?
At a minimum, once a quarter. New issues can appear as your site grows, after updates, or when plugins and themes are changed. Many UK businesses run a full technical audit once or twice a year, with lighter monthly checks in between. If you’re actively building content or running paid advertising, more frequent checks make sense.
Can technical SEO problems come back after I fix them?
Yes, they can. Websites aren’t static. Every time you add a page, install an update, or change a plugin, there’s a chance something breaks. This is why ongoing monitoring matters, not just a one-time fix. Think of it like a car, you can service it once and it’ll run better, but you still need regular checks to keep it running well.
