"Working with Angie at Kredo Design was an incredible experience — she didn’t just design a brand, she got me.From the first conversation, she understood that Nutrality wasn’t going to be soft pastels and cliché wellness quotes. I wanted something bold, modern, and rooted in science — but still personal. Angie brought that vision to life with a brand that reflects my love for red and black, a clean layout that feels strong and trustworthy, and a visual identity that actually matches my energy.She even helped guide the entire branding photoshoot, suggested a photographer, and made sure every detail aligned — from the flowers I love to the way I connect with my clients. The social media graphics, logo, and website all work together and finally feel like me.The best part? I’m attracting the kind of clients who say, “I knew I had to work with you the moment I saw your site.” That says everything. Angie is intuitive, strategic, and wildly talented — I’m so grateful we crossed paths."

On average, you can expect initial results within 3-6 months, such as cleaner indexation, stronger crawl signals, and improved long-tail visibility. Within 6-12 months, SEO momentum builds for more sustained results, including movement on priority terms, more qualified traffic, and stronger conversion performance.

SEO services in the USA deliver 10-15 hours of work per month for basic packages,15-25 hours for standard work, and 25-60+ hours for more advanced strategies.
As described by Funnel Boost Media, how the overall output is dispersed depends on the service tiers and the defined SEO strategy:
