Image Optimization at Scale

Every Image. ALT-Tagged.

Site-wide scan finds every <img> tag missing an ALT, missing a title, or with only one of the two. Bulk-generate from the image filename, page context, or your own template. Image search traffic stops leaking and accessibility scores stop getting marked down — in one optimization pass instead of a months-long cleanup.

Every Image Gets Sorted Into Three Buckets

SEObolt scans your pages, extracts every <img> tag, normalizes relative URLs, and classifies each image by what's actually on it. The triage view sorts by status so the worst offenders surface first.

Missing

No ALT, No Title

<img src="hero.jpg">
Partial

One of the Two

<img src="hero.jpg" alt="Hero">
Optimized

Both Present

<img src="hero.jpg" alt="Hero" title="Royal">

Stop Writing ALT Text One Image at a Time

For a site with hundreds of images, hand-writing every ALT is a full-week project that's never quite done. SEObolt's template system generates SEO-friendly ALTs from variables you control: the image filename (cleaned and capitalized), the page title, the focus keyword, the page URL slug. You set the format once, click Apply to All Missing, and the work is done. Good enough is better than perfect-but-never-shipped.

  • Filename source: summer-sale-banner.jpg → "Summer Sale Banner"
  • Page-context source: uses the page title + focus keyword from the SEO Analysis tool
  • Custom templates: mix-and-match variables like {filename} for {page_title} or {focus_keyword} β€” {filename}
  • Apply to all OR apply to missing only: don't overwrite existing good ALT text, just fill gaps
  • Preview before apply: see the generated text for each image before committing
Template
{filename} β€” {page_title}
Output: "Summer Sale Banner β€” Q3 Promotions"
Template
{focus_keyword} ({filename})
Output: "wedding photography (bride-portrait-2)"
Template
{filename}
Output: "Hero Banner Mountain Sunset"

Skip the Stuff That Isn't Actually an Image

The scanner reads every <img> tag on the page but skips inline base64-encoded data URLs — the placeholder pixels, lazy-load shims, and inline decorations that don't have a real filename to extract an ALT from. The result is a focused list of the actual content images on your site, not a noisy report mixed with tracking pixels and CSS-art shims.

  • Data URLs skipped: base64-encoded inline images don't pollute the report
  • Relative URLs resolved: /images/x.jpg and ../assets/y.png both normalize to absolute URLs against the page being scanned
  • Per-page audit: images are scoped to the page that contains them, so per-page status totals are meaningful

Google Image Search Is a Quiet Traffic Channel Most Sites Ignore

Image search isn't going to replace text search, but for visual industries (e-commerce, real estate, recipes, photography, travel, design) it's a real chunk of traffic and most teams never optimize for it. Same for accessibility scores in Lighthouse and the WCAG audit your enterprise prospects ask about — missing ALT text is the #1 most-flagged issue. The fix is the same in both cases: meaningful, populated ALT attributes on every content image.

Tag Every Image. In One Pass.

Site-wide scan, status per image, template-based bulk generation. Image search + accessibility + SEO scores all move at once. Included on every plan.
