You can scout for SEO clients by networking both online and offline. You should start by building a strong online presence through your website and social media. You can join freelance platforms like Upwork and Fiverr to find clients. You should also participate in SEO forums and communities to connect with potential clients. Reaching out to local businesses and offering SEO services is another effective method. You can also collaborate with web developers and designers who may need SEO support for their clients. Always provide case studies and results to build trust and attract more clients.
