Anyone purchasing a service is always interested in how long it will take to see results when considering any marketing deliverable or approach. It's crucial to keep in mind and emphasize to customers early on that SEO is a long-term investment and, if given the time it requires, may ultimately become your main source of traffic. SEO is not something that can be done once and then forgotten about. For your SEO strategy to reach and retain search engine rankings, ROI, and overall traffic growth, it requires time, planning, and readjusting. Whether you are updating your website to reflect whether you're changing your target keywords or making your site more SEO-friendly, every change you make may have a tangible impact on your SEO efforts.
