Gary Hughes

I am really happy with SEOData’s smooth method of targeting options geographically without having to resort to algorithms for SEO building. With their help, we were also able to establish easy topical crawls for our users with the use of chosen keywords instead of manual URL gathering, which made our service very manageable. I also especially appreciated their friendly pricing scheme that allowed practicality and convenience. I’m definitely recommending them to my friends and partners in the business!

Aside from the fact that our SERP requests worked really well without a hitch, each time I needed assistance, had questions to create the scripts, to construct the request, etc., someone was always available to give me the right answers promptly.
