Key performance indicators (KPIs) help you evaluate the impact of your SEO strategy. First, track your organic traffic—the number of visitors arriving through unpaid search results. Tools like Google Analytics show you which pages people visit and how long they stay.

Next, check your keyword rankings using Google Search Console or a paid tool like Semrush. Are you appearing on the first page for important phrases like “emergency plumber [Town/City]”? Monitor conversions too—this could mean phone calls, form submissions, or booked appointments. Setting up goals in Google Analytics can reveal how many enquiries you receive from organic search visitors. Finally, keep an eye on your online reviews: an uptick in positive feedback might indicate improved brand awareness. By consistently reviewing these metrics, you can see what’s working, what needs tweaking, and gauge the overall return on your SEO investment.
