Typically, our eCommerce clients start seeing long-term, revenue-focused growth about six to 12 months after launching their first SEO campaigns. However, your site can see significant improvements in traffic and revenue after short periods of time, too. For example, a technical SEO audit that resolves major site issues can improve user experience so much that your performance spikes within a few months — as it did for one client, who saw a 118% increase in revenue just one month after implementation.
