SEO Image Optimizer by DMB — Compression, Alt-Text & Filename Automation for Shopify
A Shopify app that handles the three image jobs that affect page speed and search visibility: lossless compression, auto-generated keyword-rich alt-text, and bulk filename renaming using custom templates with dynamic variables. It processes an existing catalogue in bulk, then auto-syncs new uploads. The dashboard runs a live preview simulation — showing predicted savings against current settings before anything is applied — alongside optimisation-performance reporting (total images, optimised pool, space saved, percentage reduction). Free to 500 images, then $8.99 (5,000) and $19.99 (15,000) per month. Launched 26 January 2026.

The brief
The challenge, and how we approached it
01
The challenge
Image optimisation is destructive and irreversible — over-compress and the product photography a store depends on is ruined, with no undo. Merchants also arrive with two different problems: a backlog of thousands of unoptimised images, and every new upload thereafter. And filenames like IMG_4823.jpg carry no search value, but renaming a catalogue by hand isn't feasible.
02
Our approach
Make the destructive step previewable. A live simulation calculates predicted savings against the merchant's chosen settings and shows original versus optimised side by side before anything is written — so the compression/quality trade-off is a decision, not a gamble. Compression modes are preset by intent (Most Popular, Balanced, Conservative, Custom) rather than exposing raw quality sliders, with image backup declared as a supporting feature. Filenames are generated from templates with dynamic variables, so a whole catalogue can be renamed to a consistent SEO pattern in one pass. Coverage extends across products, collections, articles, blogs and general files. Bulk processing clears the backlog; auto-sync handles everything after. Reporting closes the loop with total images, optimised pool, space saved and percentage reduction.
What we built
Six capabilities shipped for Dana's Bakery
Each one solves a specific part of the brief above.
ZIP-gated shipping
Real-time validation prevents invalid ZIP purchases from entering cart
Drop architecture
Pre-staged inventory with countdown, sold-out gates, and waitlist
Gifting flow
Message cards, recipient addressing, scheduled delivery, gift wrap
Perishable inventory
Daily inventory sync with cold-chain capacity constraints
Drop-day performance
Theme architecture handles 20× traffic spikes without latency
Recurring orders
Holiday subscription flow for repeat gifters
How it ran
10 weeks build, in four stages
Every engagement runs the same four stages, so you always know what happens next and what you owe us at each one.
Stage 1
Audit and scope
We review the current theme, apps and analytics, then write a fixed-scope SOW with named deliverables and a date.
Stage 2
Design and build
Work happens in a dev store on a Git-backed workflow. You get a preview link from week one, not a reveal at the end.
Stage 3
QA and launch
Cross-browser and device QA, redirect map, analytics verification, then a launch window agreed with you rather than dropped on you.
Stage 4
Hypercare
Fourteen to sixty days of included post-launch support while real traffic finds the edge cases.
The outcome
Where Dana's Bakery landed
Conversion is up 2.1× after the PDP rebuild, AOV is up 34% year-over-year thanks to gifting upsells, and drop days are now smooth — zero downtime across 12 drops in the past year.
