On-page SEO covers all the elements on your own site that search engines read: title tags, headings, content, images and internal links. For electricians, that means optimising service pages with keywords like “emergency electrician” and “EICR testing [location]”, ensuring your site structure is clear, and loading pages in under 3 seconds. Off-page SEO, by contrast, is everything that happens off your website that boosts your authority: backlinks from trade publications, citations in local directories (e.g. NICEIC partner listings), and customer reviews on Google. Think of on-page as sharpening your tools and off-page as getting word-of-mouth recommendations across the web. Both are critical: on-page lays the foundation, while off-page signals to Google that your electrical business is trusted and respected by the wider industry.
