Image Alt Text: The Small Detail That Gets Your Photos Found on Google

When people talk about SEO, they often jump straight to keywords, backlinks, or technical audits. And sure, those things matter. But there’s this tiny, often-overlooked detail that quietly drives traffic, helps accessibility, and gives your website that extra layer of polish: image alt text.

Sounds boring, right? Three little words shoved into your CMS while you’re uploading photos. But here’s the kicker, those three words (or, more accurately, those few descriptive sentences) could be the difference between your images showing up on Google Images or vanishing into the void.

So let’s slow down, take a breath, and talk about how something so small carries so much weight.

So… What Exactly Is Image Alt Text?

Alt text, short for “alternative text”, is basically a written description of what’s in your image. It’s what appears if the image doesn’t load, what screen readers read aloud for visually impaired users, and what Google scans to figure out if your picture is about, say, “Victoria Falls sunset” or “grilled cheese sandwich with tomato soup.”

Think of alt text like a caption, but hidden in the code. You don’t see it on the page (unless the image breaks), but search engines and accessibility tools rely on it heavily. Without alt text, your picture is just a mystery box to Google.

Why Bother? Isn’t Google Smart Enough to See Images?

This is where it gets interesting. Google is getting better at recognizing what’s inside a photo through AI and visual search technology. But here’s the truth: it’s not perfect, and it still leans heavily on context.

That’s where your alt text comes in. It’s like leaving a sticky note for Google: “Hey, this isn’t just a random photo. It’s a fisherman on the Zambezi River holding a tigerfish.”

Without it, Google might guess. With it, you’re guiding the algorithm exactly where you want it. And in SEO, clarity always wins.

The Human Side: Accessibility and Respect

Let’s not forget the human angle here. Alt text isn’t just about gaming search engines, it’s also about accessibility.

Imagine browsing the web with a screen reader. Every time it hits an image, it either reads the alt text… or says something unhelpful like “image123.jpg.” Which one makes for a better experience? Exactly.

Adding descriptive alt text is a way of making your website welcoming to everyone. And while some people treat that as a “bonus,” it’s really just basic respect. Plus, Google notices when sites are accessible. That’s not theory, that’s fact.

How to Write Alt Text Without Sounding Like a Robot

Here’s the tricky part. Alt text should describe the image, but not in a stiff, mechanical way. You don’t want to keyword-stuff it with phrases like:

“Victoria Falls best sunset photo Zimbabwe Victoria Falls tours cheap.”

That’s not helpful for humans, and Google’s smarter than that. Instead, write it like you’re explaining the picture to a friend who can’t see it:

“A golden sunset over Victoria Falls, with mist rising from the waterfall.”

Simple. Human. Descriptive. And yes, it contains relevant keywords naturally.

A Few Ground Rules (Without Getting Too Nerdy)

Let’s lay out some quick, practical guidelines you can actually use when adding alt text:

• Be descriptive, not dramatic. Skip the flowery adjectives. Stick to what’s actually in the photo.

• Use keywords naturally. If the photo is about Zambezi River fishing, include “Zambezi River fishing.” Just don’t force it.

• Don’t say ‘picture of’ or ‘image of.’ Google already knows it’s an image.

• Keep it short-ish. Aim for under 125 characters when possible. Screen readers cut off longer text.

• Context matters. Think about why the image is on the page and write alt text that supports that purpose.

Mistakes People Make (And How to Dodge Them)

Here’s where most folks trip up:

1. Leaving alt text blank. Yes, sometimes that’s okay, like for decorative flourishes or background textures. But if the image carries meaning, don’t skip it.

2. Keyword stuffing. Writing “SEO SEO SEO alt text SEO” won’t trick anyone. It’ll just look spammy.

3. Being too vague. “Nice picture” or “photo of scenery” tells no one anything useful.

4. Overcomplicating it. Long sentences stuffed with commas make it harder for both readers and search engines.

Basically, keep it clean, clear, and human.

How Alt Text Boosts SEO Beyond Images

Here’s something most people don’t realise: alt text doesn’t just help your pictures show up in Google Images. It also strengthens the page’s overall SEO.

Think of it like adding supporting signals. If your page is about “Victoria Falls travel tips” and your images have descriptive alt text like “tourists at Victoria Falls bridge” or “rainbow over Victoria Falls gorge,” you’re reinforcing the theme of the page. Google loves that consistency.

And when your images start ranking in Google Images? That’s extra traffic you weren’t getting before. In some niches, like recipes, travel, or e-commerce, image search can bring in a lot of visitors.

Tools That Make It Easier

Not everyone wants to type out alt text by hand for hundreds of photos. The good news: there are tools and plugins that help.

• WordPress users: Yoast SEO and Rank Math both highlight missing alt text.

• Shopify: Apps like SEO Manager will remind you when images lack descriptions.

• Bulk solutions: Tools like Screaming Frog SEO Spider can audit your entire site for missing or weak alt text.

That said, no tool can write it perfectly for you. They can suggest, but a human eye (and brain) is always better.

A Quick Detour: Alt Text vs. Captions vs. File Names

This is one of those things that confuses beginners. Let me clear it up.

• Alt text: Hidden description for accessibility and search engines.

• Captions: Visible text under the image. More for human readers.

• File names: What you call the actual photo file, like victoria-falls-sunset.jpg.

All three matter in their own way, and together they make your images much more SEO-friendly. But alt text is the one most people forget.

Can Alt Text Really Get You Onto Google Images?

Yes. But here’s the nuance, it’s not just alt text. Google looks at the whole package: page content, file names, image titles, and surrounding text.

That’s why alt text works best when it’s part of a bigger strategy. For example:

• A blog post about Zambezi fishing.

• Photos named zambezi-tigerfish.jpg.

• Alt text: “Angler holding a tigerfish on the Zambezi River.”

• Caption: “Tigerfish caught near Livingstone, Zambia.”

Now you’ve got context everywhere. Google can’t miss it.

Common Questions About Alt Text

Let’s tackle a few quick FAQs, because these always come up:

A Gentle Reminder: SEO Isn’t Just About Google

One last thought. It’s easy to obsess over rankings and forget the bigger picture. Alt text isn’t only about getting traffic, it’s about making your site usable and thoughtful.

When you write good alt text, you’re showing respect for your audience. You’re giving visually impaired users access. You’re helping search engines understand your content better. And yes, you’re giving yourself a better shot at those sweet, sweet Google Image clicks.

It’s rare in SEO that something so small delivers benefits across accessibility, UX, and traffic. Alt text does all three.

The Power of Small Details

Alt text isn’t glamorous. You won’t brag about it at a networking event. But here’s the truth: most websites don’t bother, which means you can gain a competitive edge just by paying attention.

Think of it like seasoning in cooking. Too much, and it ruins the dish. None at all, and it tastes flat. But just the right amount? Suddenly, everything works.

So the next time you upload an image, pause for 30 seconds and write a clear, helpful description. It may feel small in the moment, but it adds up, picture by picture, page by page, until your site tells a story Google can’t ignore.
