Countless people and agencies enter the web development business without formal software education or training. Almost every WordPress site is built differently depending on the approach taken by the developer. Additionally, free plugins are often not updated, making them a security risk for hackers to exploit and access your site.
If you’ve got a flashy WordPress site built on a template, you’ll have a website with enough code for 20 websites. No matter how eye-catching your homepage looks or how sophisticated your choice of font is, your site is bloated, slow to load, and without a chance of ranking on Google’s first page.
