Technical SEO Explained for Business Owners (No Jargon)
Technical SEO is the foundation that lets Google find, understand and trust your website. Here is what it covers, in plain English.
You can write the best content in your industry, but if search engines cannot crawl, understand or load your pages properly, they will not rank. Technical SEO is the behind-the-scenes work that makes your site easy for Google to read. Here are the essentials, without the jargon.
1. Can Google find your pages? (Crawling)
Google discovers pages by following links and reading your XML sitemap, a list of the pages you want indexed. Your robots.txt file tells crawlers which areas to skip, such as admin pages. A single wrong line in robots.txt can hide a whole website, so it is worth checking.
2. Are your pages in Google? (Indexing)
Google Search Console shows which pages are indexed and why others are not. Common problems include accidental noindex tags, duplicate pages, thin content and pages that return errors.
3. One page, one address (Canonicals and redirects)
If the same page loads at several addresses (with and without www, with and without a trailing slash, or through tracking parameters), Google may split its ranking signals. A canonical tag tells Google which version is the main one, and 301 redirects send old URLs to new ones after a redesign.
4. Speed and Core Web Vitals
Google measures real-user experience with three Core Web Vitals:
- Largest Contentful Paint (LCP): how quickly the main content appears. Aim for 2.5 seconds or less.
- Interaction to Next Paint (INP): how quickly the page responds to taps and clicks. Aim for 200 milliseconds or less.
- Cumulative Layout Shift (CLS): how much the layout jumps while loading. Aim for 0.1 or less.
Compressing images, using modern formats such as WebP, good hosting and removing unnecessary plugins usually make the biggest difference.
5. Mobile-first
Google primarily uses the mobile version of your site for ranking. Text should be readable without zooming, buttons easy to tap and nothing important hidden on small screens.
6. Structured data (schema)
Schema markup is code that labels information on your page: your business details, services, articles, FAQs, products and reviews. It helps search engines and AI tools understand your content and can unlock richer search results.
7. Security
Every website should use HTTPS. Browsers warn visitors about insecure sites, which destroys trust.
Where to start
Set up Google Search Console, submit your sitemap and check the Pages and Core Web Vitals reports. If those reports are full of warnings, a technical audit will prioritise what to fix first. Our SEO team works alongside developers, so fixes get done, not just listed.
Frequently asked questions
How often should a technical SEO audit be done?
A full audit once or twice a year, plus monthly checks of Google Search Console, is enough for most business websites. Always audit after a redesign or migration.
Is technical SEO a one-time job?
The big fixes are usually one-off, but new content, plugins and site changes can introduce problems, so ongoing monitoring is important.
