I’ve been in this industry for 12 years. I’ve sat in rooms with developers who think SEO is "magic" and designers who treat the website like an art gallery where whitespace is more important than metadata. The latest battle? The blank ALT attribute.
I get the ticket: "Hey, the designer left all the product images blank for the ALT tags. Does this actually hurt our rankings?"
The short answer is yes, but probably not for the reason you think. Google doesn't just "penalize" you because you forgot to describe a photo. They penalize you because you’re failing the fundamental test of accessibility signals and contextual relevance.
Why Google Cares About Your ALT Attributes
Let’s look at what Google actually says. They aren't in the business of guessing what’s in a photo, even with their fancy AI. ALT text is how you communicate with search engine spiders about the *content* of an image. If your image represents a piece of hardware and the ALT text is blank, you are missing an opportunity to rank in Google Images, which is a massive traffic driver for e-commerce and technical sites alike.
When you have missing alt attributes, you aren't just ignoring SEO; you are telling visually impaired users that your site is irrelevant to them. Google treats accessibility as a proxy for a high-quality user experience (UX). If you provide a poor experience for screen readers, you are signaling to Google that your site isn't fully optimized designnominees for all users.
Pro-tip: Stop stuffing keywords into ALT text. If I see "red-sneakers-running-fast-cheap-sneakers" in an ALT tag, I’m sending it back to your team. Use descriptive language. If the image is just a decorative border, leave it null (`alt=""`). If it's a product, describe it like you would to a friend over the phone.
Mobile-First Indexing and the Bloated Page Problem
One of my biggest pet peeves is the "giant mobile page" that scrolls for an eternity because a designer didn't consider that mobile-first indexing is now the standard. If your mobile layout is pulling the same high-res desktop images just because they "look pretty," you’re killing your Core Web Vitals.
When I work with clients who have sites like Design Nominees or portfolios like Technivorz, we focus on responsive design that isn't just about resizing—it's about serving the right asset for the right device.
The Mobile UX Checklist:
- Hide secondary content: If it’s not mission-critical for the mobile user, hide it via CSS. Don’t make the browser load it and then use JavaScript to shrink it. Tap-friendly buttons: Ensure your CTA buttons are at least 44x44 pixels. If a thumb can’t comfortably hit it, Google’s bots consider it a failure. Navigation labels: Never use "Stuff," "More," or "Extras." Be specific. If it’s a menu, call it "Menu." If it’s a catalog, call it "Shop."
Image Formats: JPEG, PNG, and SVG
Designers often choose formats based on what looks best in their design software. You need to choose based on what performs best on the wire. Here is the reality of your image formats:
Format Best Use Case SEO Impact JPEG Complex photographs with many colors. Highly compressible; great for load speed. PNG Images with transparent backgrounds. Heavier; can hurt LCP (Largest Contentful Paint) if not optimized. SVG Logos, icons, and simple illustrations. Scalable and incredibly light; essential for responsive design.Tools I Actually Use
I don't leave performance to chance. Before any image hits the live server, it goes through a compression workflow. If you aren't using these, your site load speed is likely dragging your rankings down, regardless of your ALT text:
- ImageOptim: The gold standard for stripping out unnecessary metadata and compressing files without losing visual quality. It’s a "tiny fix" that pays dividends in milliseconds. Kraken: Excellent for bulk optimization. If you have a site with thousands of product SKUs, this is the only way to scale your image SEO basics without losing your mind.
My "Tiny Fixes That Move Rankings" List
Over the last decade, I’ve kept a notebook of the small, boring things that actually impact search performance. These aren't "hacks"; they are the foundational work that most agencies skip.
Audit your H1/H2 hierarchy: If your CSS makes a header look small, it doesn't mean it isn't an H1. Ensure your HTML tags follow a logical, semantic structure. Fix the ALT gaps: Go through your site and ensure every image has a descriptive ALT attribute. If it's a product, include the model name. Compress the hero images: If your top-of-page image is over 200KB, it's too big. Period. Use ImageOptim. Delete "Menu" fluff: Audit your navigation bar. If you have a link called "Stuff," change it to what the user is actually looking for (e.g., "Services" or "About Us"). Check click targets: Use Google Search Console’s "Mobile Usability" report to find elements that are too close together.Final Thoughts
Is a blank ALT attribute the end of the world? No. But in a competitive space, SEO is a game of marginal gains. When your developer skips the alt tags, they are essentially taking a knife to your accessibility signals. When your designer pushes a 4MB header image, they are tanking your load times.
Your job as the content editor is to be the bridge. Tell your designer: "I love the aesthetic, but we need to talk about load times and accessible metadata." If they push back, show them the data. Google doesn't reward pretty sites that fail to perform; it rewards sites that offer a seamless, fast, and accessible experience for everyone. Don’t let "design choices" be the reason your site never hits page one.
