How to Optimize Images for SEO

When you publish a fantastic, thousand-word article on your website, you know that Google's algorithm bots crawl through every single letter, indexing your content to serve it to the right searchers. But what happens when the bot reaches a beautiful, full-color infographic you spent three hours making?

The bot sees absolutely nothing. Algorithms are blind to aesthetic beauty. They rely exclusively on the metadata, the code, and the surrounding context to figure out what an image is about. If you are uploading images named `IMG_99482.jpg` to your website, you are actively throwing away massive amounts of highly valuable SEO (Search Engine Optimization) traffic.

Rule 1: Rename the File Before Uploading

The absolute most basic, yet most powerful action you can take happens before the file ever touches the web. Your camera might name the file `DSC0001.jpg`, but Google has no idea what that means.

Before you drag that file into WordPress or Shopify, rename it using descriptive, hyphenated keywords. If you are selling a blue leather wallet, the file name should be: `mens-blue-leather-bifold-wallet.jpg`. Now, when someone goes to Google Image Search and types "blue leather wallet," Google knows exactly what your image is.

Rule 2: Master the 'Alt Text'

When you upload an image to an HTML website, there is a core attribute tag designated as `alt="..."`. Alternative Text serves two crucial purposes:

1. Accessibility: Screen-reading software for visually impaired users reads the Alt Text aloud, describing the image to them.
2. The Google Crawl: It provides a direct, contextual definition of the image to search bots.

Don't keyword stuff your Alt Text! Write it like a normal human describing a photo to a blindfolded friend. Good Alt Text: "A close up angle of a blue leather wallet resting on a wooden desk."

Rule 3: Ruthless Compression

As previously mentioned across our blog, page speed is a massive core ranking factor for the Google algorithm. Even if your image has the best name and the perfect Alt Text, if it takes 5 seconds to load because the file is 8 Megabytes, Google will severely penalize your site's ranking.

By treating your images exactly like you treat your written text, you open up an entirely separate, highly lucrative avenue of organic Google traffic.
