In order to build a site optimized for organic search engine rankings, it is important to implement certain standards throughout the code. These include:

- Specifying an alt tag on images

- Using the correct HTML tags for content hierarchy i.e., <h1>/<h2>/<h3> and p

- Connect the site to the company’s social pages

- Add an XML sitemap

Optimizing websites is an art that few are familiar with. The more the engineer is able to list off the top of their head, the more likely they are to do all of the following naturally as they code instead of having to return later.

(Also, typically a professionally constructed site should score over 75 percent when analyzed by gtmetrix.com, which can also serve as a checklist.)

- Optimize all assets
- Place all assets on a separate, cookie-free domain. Using a CDN is best
- Avoid inline JavaScript and CSS
- Enable gzipping
- Ensure all code is minified
- Defer parsing of JavaScript
