The Confusion Between Tags and Alt Text

Squarespace gives you multiple fields that all feel like they might be doing something for search: image tags in the asset library, filename, caption, alt text, and the title of the page the image sits on. Because the platform uses the word "tags" in more than one context, many site owners assume that adding tags to images is an optimisation activity. In most cases, it is not.

Tags applied to images inside Squarespace asset management or gallery organisation are primarily internal metadata. They help you filter, sort, and manage your own library, and in some gallery contexts they power filtering for visitors. What they generally do not do is appear in the public HTML of the page in a way search engines interpret as a description of the image. The label that genuinely matters for image search and accessibility is alt text, and that is a different field entirely.

This distinction matters because time spent tagging hundreds of assets for organisational tidiness produces no ranking benefit, while five minutes writing good alt text on your most important images produces a real one.

How AAMAX.CO Helps You Optimise Images Properly

We are a full-service digital marketing company offering web development, digital marketing, and SEO services worldwide, and image optimisation is one of the fastest wins we find on template-based sites. Our audits identify which images are missing descriptive alt text, which files are oversized and slowing down your pages, and where filenames and captions could be doing more work. If you want a systematic clean-up rather than guesswork, our SEO services cover technical image handling alongside content and structure. You can hire AAMAX.CO to review your Squarespace site and deliver a prioritised list of fixes that actually move rankings.

What Actually Influences Image Search Visibility

Alt text is the primary descriptive signal. It exists to describe the image for people using screen readers, and search engines use it to understand image content. Good alt text is specific and natural: describe what the image shows in the context of the page. If the image is a product, name the product. If it is a photograph of a completed project, describe what the viewer is looking at. Avoid stuffing keywords, avoid starting with phrases like "image of", and leave alt text empty for purely decorative graphics so assistive technology can skip them.

Filenames carry a smaller but genuine signal. Uploading a file named with a string of camera-generated characters tells search engines nothing. Renaming it to a short hyphenated description before upload is a one-second habit that helps. Note that on Squarespace you must rename before uploading, because the platform does not let you rewrite the stored filename afterwards.

Captions provide visible on-page context. Because captions are real text rendered on the page, they contribute to the overall content of that page and often improve user comprehension at the same time. Not every image needs one, but for editorial, portfolio, and explanatory images they are valuable.

Surrounding content matters too. Search engines evaluate images partly by the text near them, the heading of the section, and the topic of the page. An image placed within a well-written, clearly headed section is easier to interpret than one floating in a gallery with no context.

Performance: The Image Factor With the Biggest Impact

For most Squarespace sites, the single largest image-related SEO issue is not labelling at all. It is weight. Portfolio and photography-heavy templates encourage large, full-bleed imagery, and users frequently upload enormous files straight from a camera or a design tool. Squarespace does generate responsive variants, but it cannot undo the damage of an unnecessarily huge original, and the largest visual element on a page is very often what determines your Largest Contentful Paint score.

Practical steps help enormously. Resize images to the maximum dimensions they will realistically be displayed at before uploading. Compress them with a quality setting that keeps them visually clean while cutting file size substantially. Limit how many large images load above the fold. Be cautious with heavy background videos and dense image grids on landing pages. Every one of these choices affects Core Web Vitals, which in turn affects both rankings and conversion.

Galleries, Lightboxes, and Discoverability

Gallery blocks and lightbox viewers create additional considerations. Images loaded dynamically as a visitor scrolls or clicks may be discovered less reliably than images present in the initial markup. If specific images are commercially important, for example key product shots or signature project photography, give them prominent placement in standard content blocks rather than burying them inside a large lazy-loaded gallery.

It also helps to give important images their own supporting context. A dedicated project page with a headline, descriptive copy, and two or three well-labelled images will typically outperform a single gallery page containing sixty untitled photographs, because the former gives search engines a clear topic to associate with the imagery.

Structured Data and Sitemaps

Squarespace generates a sitemap automatically, which covers your pages. For image-driven businesses, using appropriate structured data on product and article pages helps search engines associate specific images with specific entities, and it can support richer presentation in results. Platform limitations mean this sometimes requires code injection, so it is worth planning rather than improvising.

A Practical Checklist for Squarespace Images

Rename files descriptively before uploading. Resize and compress every image to sensible dimensions. Write specific alt text for every meaningful image and leave it blank for decorative ones. Add captions where they genuinely help the reader. Place commercially important images inside contextual content sections rather than only in galleries. Keep the number of large images above the fold low. Use image tags for your own organisational convenience, and do not expect them to influence rankings. Review page speed after any significant visual update.

Applied consistently, this checklist improves accessibility, performance, and image search visibility at the same time, and it complements the broader work covered by our digital marketing team when images are also being used across campaigns.

Conclusion

Tags on your Squarespace images are mainly an organisational tool, not a ranking lever. The labels that matter are alt text, filenames, captions, and the content surrounding each image, while the biggest technical factor is file weight and its effect on loading speed. Focus your effort there and your images will start earning visibility instead of quietly holding your site back.
