Client Case Studies

So many small businesses in Puerto Rico, yet so few modern professional websites exist.

There are far too many local businesses that don’t even have a basic mobile-first SEO-optimized website. 

 Nearly every business would benefit from the services of a competent professional digital marketing agency. 

Too many of our neighboring Puerto Rico businesses are on the wrong side of this equation. These websites routinely fall short of these important professional website standards, and others. 

In my 10-years of experience of working directly with small business owners, the majority of them do not have the prerequisite technical or Internet marketing knowledge to effectively:

  1. Discern the differences between vendors
  2. Evaluate technologies and strategies.
  3. Quantify price and measure value.   

There are many measurable differences between a professional website company, and one that is not.

Q: Can Facebook replace a small business website?

A: Maybe for a person but not for a business!

Many individuals and aspirational website designers choose easy-to-use yet inferior CMS platforms (Wix, Weebly,, etc.).

Few understand (and even fewer adhere) to important professional standards, (i.e.) Google Webmaster, WC3, page speed, security, and other industry standards.

  • Rank organically (SERP) on Google
  • Have basic on-page SEO
  • Meet Google’s mobile-first standards
  • Are secured with an SSL Certificate
  • Modern Responsive & Adaptive design
  • Content updated regularly
  • Maintained regularly
  • Loads pages in under 4 seconds
  • Include accurate analytic
