Missing alt text and oversized images don't show up in a quick look.

A product page looks fine to a visitor with a 4MB hero image and no alt text on the gallery. Neither is visible without checking — and at scale, across tens of thousands of images, nobody's checking by hand.

Common challenges

Invisible to a visitor. Costly anyway.

  • A product image ships without alt text on thousands of pages, invisible to accessibility tools and image search alike, and nobody notices because the page renders fine.
  • Images get uploaded at their original size and never compressed, quietly adding seconds to load time across an entire template.
  • A media reference breaks after a CDN migration or a content restructure, and the broken image sits there until someone happens to scroll past it.
  • None of this is visible from a glance at the page. It only shows up once something actually checks every image, not a sample.

What needs to happen: every image needs checking, at scale, for alt text, size relative to display, and whether the reference actually resolves — not spot-checked on a handful of pages.

How SEORCE does it: every image within crawl scope is audited on the same schedule as the rest of the crawl. Writing accurate alt text is a content decision that needs understanding what's actually in the image, so it's flagged for your team rather than generated automatically — SEORCE tells you exactly which images need it.

What SEORCE flags vs what needs a person.

Alt text needs someone who understands what's actually in the image — that stays with your team, image by image, prioritised by which pages carry the most traffic. Oversized images and broken references are flagged with the exact file and page, ready for your team to resize, compress or replace.

What does Assets & Media check?

Assets & Media audits every image and media reference across a site during the continuous crawl, not a sample. It flags images missing alt text, images significantly larger than their display size warrants, and media references that no longer resolve. Findings are grouped by shared template, so an issue affecting thousands of pages shows up as one pattern rather than thousands of line items. Writing accurate alt text requires understanding the image's actual content, so it's flagged for your team rather than generated automatically.

Key facts

  • Audits every image within crawl scope, on the same schedule as the rest of the crawl
  • Flags missing alt text, oversized images, and broken media references separately
  • Groups findings by shared template or pattern
  • Alt text stays a content decision for your team — SEORCE identifies what's missing, not what to write

Common questions

Frequently asked about assets & media.

Updated 18 September 2026
Does SEORCE write alt text automatically?+

No. Writing accurate alt text requires understanding what's actually in the image and how it should be described, which is a content decision, not a mechanical fix — SEORCE flags every image missing it so your team can prioritise.

What counts as an oversized image?+

An image file significantly larger than it needs to be for the size it's actually displayed at on the page — a common, invisible cause of slow page loads.

How does this find broken media references?+

The crawl checks that every image and media reference on a page actually resolves, flagging ones that 404 or point to a resource that no longer exists.

Does this check every page or a sample?+

Every page within crawl scope, on the same schedule as the rest of the crawl — not a sample.
