SEO has changed more in the last few years than in the previous decade. It’s no longer enough to “stuff keywords” into the text: Google evaluates your website as a complete system, and a large part of that evaluation is purely technical.
1. Core Web Vitals are still a real factor
Google measures three specific things about the loading experience:
- LCP (Largest Contentful Paint): how long the main content takes to appear.
- INP (Interaction to Next Paint): how long the page takes to respond to a user interaction.
- CLS (Cumulative Layout Shift): how much the content “jumps” while loading.
These aren’t abstract metrics: they directly reflect whether your website feels fast or slow to a real user. A website with unoptimised images, excessive JavaScript or poorly loaded fonts drags these metrics down, and your rankings with them.
2. Crawling and indexing: if Google can’t read it, it doesn’t exist
A surprisingly common mistake: websites with valuable content that Google simply can’t crawl properly because of technical problems — accidental blocks in robots.txt, outdated sitemaps, broken internal links, content that relies on heavy JavaScript without server-side rendering. Before optimising content, you need to make sure Google can access it without friction.
3. HTTPS, security and technical good practice
A correctly configured SSL certificate, reasonable security headers and no mixed content (HTTP resources on an HTTPS page) are still basics Google expects. They don’t give you a competitive edge on their own, but their absence does count against you.
4. Structured data (Schema.org)
Marking up your content with structured data — products, articles, FAQs, local business — helps Google understand exactly what each page is about, and enables rich results in search (stars, prices, expandable FAQs). It’s one of the most underused technical areas among small businesses, and one with the biggest visual impact on search results.
5. A real mobile experience, not just “responsive”
Google mainly indexes the mobile version of your website (mobile-first indexing). Your website “looking fine” on mobile isn’t enough: buttons must be easy to tap, text readable without zooming, and forms usable with a touch keyboard. A website that’s technically responsive but awkward to use on mobile still hurts the experience.
6. Information architecture and internal linking
How you structure your URLs, how pages link to each other and how you group related content (categories, tags, similar content) helps Google understand which pages matter most within your website. A flat, disorganised structure dilutes the authority of your most important pages.
What this means for a small business
Technical SEO isn’t a luxury reserved for large companies: it’s the foundation everything else is built on. You can write the best content in your sector, but if your website takes four seconds to load or Google can’t crawl it properly, that content will never rank. Before investing in more content or link-building campaigns, it’s worth doing an honest technical audit of what you already have.
