As much as I want an attractive blog, I prefer a blog that is more discoverable and outperforms others. That makes the eye-candy totally worth it and I feel great knowing that I do the best I possibly can to make - what I hope to be - a great experience for you. Your feedback is whole-heartily welcome!

But wait up. What do I actually mean by highly discoverable and outperforming website? 🤔 Is it just a bunch of green metric scores? Yes. I honestly don't know enough so I rely on metrics, tools, the web and my tiny bit of experience to guide me.

The results and optimization journey are a double-edged sword for me. On one side, the more important one, is the need for me to maximize your usability and experience without compromising on important things like data costs and page load speed. The site must be discoverable by search engines and can be shared nicely on different social platforms. On the other side, the more greedy one, is a playground for me to learn and explore different approaches and techniques that I can take to make an interesting and well performing website that belongs to me.

This curiosity brings about knew skills in my professional capacity.

In this article, I will share how I built my blog using Gatsby, Netlify, Algolia, Lighthouse, many metrics sites, and such and share what my thought patterns and process is.

Performance first

I put performance first and I am very pedantic about it. Fortunate for me, this naturally ropes in simplicity in my design. Every feature is meticulously thought through by reasoning about it with some questions:

  • What is the purpose of the feature?
  • How should the feature be visualized?
  • Where will the components be rendered?
  • How can I render it in such a way that it enhances the user experience?

Once implemented - usually in a batch of features - I will analyze the website to ensure there is little to no degradation. Where necessary, back to the drawing board I go.

Every one of my features has 5 simple goals:

  • Be data efficient by using as little data over the wire as possible to ensure data costs are kept as low as possible.
  • Be snappy with the response time when rendering pages and components from the server to the client.
  • Stay simple and minimalist in the design to avoid cognitive overload for readers.
  • Uphold a user-friendly experience and journey by creating meticulously placed components.
  • Developer friendly to make it easier for me, as the developer, to come back to the code and know what I am doing.
  • Responsive to ensure that the website is adequately accessible via different screen sizes and devices. Google Page Speed will give you mobile and desktop scores.



Gatsby provides development teams an open source frontend framework for creating dynamic, optimized websites and a cloud platform for delivering them on a blazing fast edge network.

I've used Gatsby for a few years and it has become my goto due to its simplicity, official & community plugins, ridiculously cool features, out of the box performance and wide support. It is a pleasure to work with, treats me well as a developer, gives me great results and is therefore ideal for my blog.

One particular feature, GraphQL, gives me the ability to interact with my data in interesting and convenient ways.

A little side step here, in 2020, I created gatsby-remark-interactive-gifs [ source code] [article]. Once markdown files are generated, gifs are turned into interactive components. The gif does not load on page load rather you can click on a play button when you get to the gif. The gif will then load and you can stop it at any time. I am really proud of my creation ⭐


With that said, you can imagine the incredible number of plugins available that allow you to do just about anything. The plugins below helped a lot with my SEO.

  • gatsby-plugin-advanced-sitemap generates a single or multiple sitemaps with full XSL templates to make them neatly organized and human & machine readable, as well linking image resources to encourage media indexing.

  • gatsby-plugin-google-gtag easily adds Google Global Site Tag to your site.

  • gatsby-plugin-manifest creates the web app manifest (part of the PWA specification) which allows users to add your site to their home screen on most mobile browsers. The manifest provides configuration and icons to the phone.

  • gatsby-plugin-robots-txt create robots.txt for your site.


Netlify ships web apps faster using an intuitive Git-based workflow and powerful serverless platform to build, deploy, and collaborate.

They make it super easy for developers to host websites in a way that is simple, scalable and secure.

I have also been using Netlify for a few years. It's simple: I write my code, push to GitHub, Netlify hooks in and triggers a build automatically then deploys upon success. I get notified if the build breaks with a full log. Netlify even has a CLI tool that lets you configure continuous deployment straight from the terminal.


Algolia enables developers to build next generation apps with APIs that deliver relevant content in milliseconds.

I have noticed websites using Algolia for search, became curious and decided to give it a try. They do not disappoint! I successfully index my blog and get near to instant results with search.

Tailwind CSS

Tailwind CSS lets you rapidly build modern websites without ever leaving your HTML. It is a utility-first CSS framework that can be composed to build any design, directly in your markup.

I just wanted to see what all the hype was about. I gave it a try and got sucked right in. I can create a slick user interface with writing little to no CSS at all. The little bit of SASS I have left on my site is to style my articles which are generated from markdown.


There is a big difference between running a Gatsby website in development & production mode.

Development mode is optimized for rapid feedback and extra debugging information which means that files don't appear the same as they do in production (minified and bundled). It ships with features like live reloading and Gatsby's data explorer.

Production mode minifies and optimizes the site by packaging up config, data, and code, and creating all the static HTML that eventually gets rehydrated into a React application.

Libraries like Tailwind get their CSS purged, which means that the build removes unused CSS for maximum performance, while other files get compressed, minified and bundled during a production build.

This means that the output between development and production modes are vastly different and that what works in development mode does not mean it will work in production mode. That is why you need to:

  • Test your features using the production build as regularly as you can.
  • Find local tools to run your website against numerous tests. I use Lighthouse which is installed in the Chrome DevTools.
  • Run your tests with an optimized production build.
  • Run your tests in incognito mode.
  • Run your tests without any browser extension interference.

If you can't find a local testing tool suite then deploy your website somewhere (Netlify, Heroku) and get it tested online using the Metrics tools below.


Use tools to test and analyze your website. You can get reports that offer scores, essentials, diagnostics, opportunities and audits.
