Ali Messum: Just post your any query and see what`s the answer and in that way you can better know a person in SEO field
Harley Helmer: Testimonials and case studies show what people have done and what the outcome was. Here’s one of ours for reference: https://vimeo.com/381966090
Buth Main: As a client I never give permission to share my case. Also it makes a little sense because one project differs from other project. And... in fact, less than 40% of marketing projects are successful. But I`ve never seen SEOs who shared their failures.
Jaroslaw Pidburskyj: Dead simple, have they a website? Test their Pagespeed should hit min 90%, test their SEO with an audit should hit min 85%+. If both pass then you’ve probably found your man or woman. Testimonials can be doctored.
Amru Shaban: Jaroslaw Pidburskyj same can be what you said by a basic web developer and content wtiter with a checklist for on-page seo
Jaroslaw Pidburskyj: If you don’t do your research and just go with them based on their testimonials then you’ll get a mirror image to their website and if they are poor in both areas then it’s your loss.
Chris Edwards: Ask them for testimonials that can be verified.
Jaroslaw Pidburskyj: Whoever you ask, if you have the right URL then with just less than 10 adjustments the SEO scoring for the keyword within the url will score 100%, you cannot better 100%.
Buth Main: Ask them:1. Their definition of SEO.2. Their approach of doing SEO.3. A few methods on-page optimization or content creation.4. Didi they have the bad projects?
How to be sure about choosing someone to do SEO project for yourself. I mean how to see what they are capable of ?? Can someone input please..
