Year-over-Year (YoY) Growth

Year-over-Year (YoY) growth is the standard financial and analytical metric used to compare a specific performance indicator (such as organic traffic, conversion rate, or total revenue) in one period against the exact same period in the previous year (e.g., Q3 2024 vs. Q3 2023). In SEO, analyzing month-over-month (MoM) data is often highly misleading due to the massive impact of seasonal search trends (e.g., e-commerce traffic always spikes in November and crashes in January). YoY growth is the only accurate method for neutralizing seasonality and definitively proving whether an SEO campaign is actually generating compounding, long-term business growth.

Year-over-Year (YoY) Growth Simplified

Year-over-Year growth is comparing how your website did this month compared to the exact same month last year. Because some businesses are naturally busier in the summer than the winter, comparing this July to last July is the only way to know if your business is actually growing.
