Since you admitted that you are a freelancer it's important to show us your success rate who are your clients and give us a list of sites that you ranked and why would potential clients pick you instead of more established SEO companies, It is better to tell us if you are affiliated on SEO companies like all SEO freelancers are doing.

Honestly, I have a hard time believing an SEO specialist who does not have his own site to showcase his service, and rank it in his chosen niche, if there is one, better to include it here.

When it comes to SEO, results and testimonials are very important.
