Amazon Changed SEO Again (And No One Told You): Alt Text Is No Longer Indexing

Image alt-text appears to no longer contribute to Amazon keyword indexing, so any ranking power it used to provide is gone. To recover, move those lost keywords into the fields that still index — titles, bullets, backend search terms, and A+ content — and use Search Query Performance data to find and refill the gaps. Amazon made this change quietly, without updating public docs, so the fix is to audit your keyword coverage and rebuild relevance through content that the algorithm still reads.

What Actually Changed With Amazon Alt-Text?

Image alt-text fields (ALT tags) no longer appear to contribute to Amazon’s keyword indexing. The likely reason is that Amazon now leans on machine vision and image-context alignment rather than a manual semantic field, so it has deprecated alt-text as a ranking input. If alt-text was carrying keywords you did not place anywhere else, you may have quietly lost traffic on those “shadow queries.”

A quick proof test: compare the terms you used in alt-text against your current Brand Analytics and Search Query Performance impressions. Gaps between the two often reveal exactly where coverage was lost.

Which SEO Levers Still Matter on Amazon?

Titles and bullets

• Front-load your core terms in the first 60 characters
• Use synonyms and long-tail secondary terms in the bullets
• Keep the copy flowing naturally so bullets improve both readability and context

Backend search terms

• Still a primary hidden indexer; check the character and field limits for your marketplace
• Separate terms with a space; do not include ASINs or competitor brand names
• Favor term frequency over term stuffing — do not repeat the same word multiple times

A+ and Enhanced Brand Content

• Use densely contextual visuals with keyword-relevant captions to feed Amazon’s image and content models
• Comparison charts and feature lists add relevancy signals

Search Query Performance and additional fields

• Use impression, click, and purchase share gaps to spot lost visibility, then reintroduce gap keywords into title, bullets, and backend
• Fill in subject-matter fields, intended use, and target audience where available
• Review the early search-term report and map those keywords back into your content

How Do You Audit and Recover Lost Rankings?

1. Keyword gap audit: pull historical search-term reports, find terms that dropped impressions, and cross-check them against the alt-text phrases you used.
2. Content repair: edit titles and bullets to reintroduce lost terms where relevant, and occasionally remove and re-add a keyword to measure its impact.
3. Backend clean-up: remove duplicate terms and use more natural phrasing, for example “cream for dry skin overnight” instead of raw stacked keywords.
4. SQP monitoring: check weekly for slipping terms and restore them into content before they disappear entirely.
5. Creative backstop: use image captions and on-image text cues, plus a strong main image, to keep relevant concepts visible to shoppers and to Amazon’s models.

What Is a Realistic 30 to 90-Day Recovery Plan?

Days 1 to 30

• Run the keyword gap audit and identify lost alt-text phrases
• Update titles and bullets with recovered terms
• Clean up backend search terms by deduping and expanding
• Monitor SQP for returning impression share

Days 31 to 60

• Test A+ content updates on your key SKUs
• Use search-term harvesting to fill blind spots
• Track rank and impression curves for priority terms

Days 61 to 90

• Continue refinements and expand beyond top SKUs into the long tail
• Re-audit term performance monthly
• Adjust ad targeting toward reclaimed terms and new keyword opportunities

As an agency that manages Amazon accounts for established consumer brands, Marketplace Valet treats algorithm shifts like this as a prompt to re-audit keyword coverage rather than panic. The brands that find their gaps, repair content, and rebuild relevance across content, backend, and SQP are the ones that protect their traffic and rank.

Frequently Asked Questions

Does Amazon alt-text still help with SEO?

Image alt-text no longer appears to feed Amazon’s keyword indexing, so it should not be relied on for ranking. Treat it as an accessibility and presentation field rather than an SEO lever.

How do I know if I lost traffic from this change?

Compare the keywords you placed in alt-text against your current impressions in Brand Analytics and Search Query Performance. Terms that dropped impressions and were not covered elsewhere are likely the ones you lost.

Where should those keywords go now?

Move them into the fields that still index: front-loaded titles, bullets, backend search terms, and keyword-relevant A+ content captions. Keep the phrasing natural so it reads well to shoppers.

How often should I check Search Query Performance?

Check weekly for slipping or lost terms so you can restore them into content before they disappear entirely, and run a deeper term-performance re-audit monthly.

Should I stuff backend search terms with every keyword?

No. Favor term frequency over term stuffing, avoid repeating the same word, and never include ASINs or competitor brand names. Dedupe and expand coverage instead of padding.
