E1139: Image backlinks work surprisingly well for SEO, and one old experiment found they could even outperform exact-match anchor text links. I break down an SEO experiment from Dan Petrovic that tested four different types of backlinks to see which had the greatest effect on rankings. The test compared: - An exact-match anchor text backlink - A naked URL placed after the target keyword - An image backlink using the target keyword as the image alt text - A "click here" backlink with the target keyword placed near the link The result that stood out: the image backlink with the target keyword in the alt text performed better than every other link type in the experiment, including the exact-match anchor text link. The experiment was conducted in 2013, so I also look at whether the idea still matters today: Linked image alt text is still treated as anchor text for SEO purposes. I also cover more recent research from Kevin Indig and Semrush analyzing 35,000 backlink data points across 1,000 domains, which found that image backlinks correlated more strongly with AI search visibility than text links. Then I get into the practical part: how to actually build backlinks using images. We break down: - Why image backlinks affect search rankings - What Dan Petrovic's anchor text proximity experiment tested - Why the image backlink beat the other link types - How Google uses image alt text as anchor text - Why image backlinks may also matter for visibility in AI search - How to use infographics, charts, photos, maps, and product images for link building - How reverse image search can uncover websites already using your images - David McSweeney's TRUST formula for creating images journalists and bloggers may want to use - How to find topics journalists are already covering - How to turn research and data into simple visual assets - How to find journalists and bloggers who may be interested in your images - Why niche-specific stock photos can continue generating backlink opportunities after you publish them - Why you should still be careful with exact-match anchor text I explain a simple image strategy: create original niche-specific photos, charts, data visualizations, infographics, or other useful images and make them available on stock image platforms. If bloggers, journalists, or other websites use those images, they may credit the source. You can also periodically reverse image search your work to find websites that used an image without attribution and contact them to request a source link. The important point is that link building does not always have to start with asking someone to link to a page. You can create assets people already have a reason to use. ⭐️ SEO Sherpa: SEO Experiments - https://seosherpa.com/seo-experiments/ ⭐️ Dejan Marketing: Anchor Text Proximity Experiment - https://dejanmarketing.com/anchor-text-proximity-experiment/ ⭐️ Growth Memo: How AI Really Weighs Your Links - https://www.growth-memo.com/p/how-ai-really-weighs-your-links-analysis ⭐️ Ahrefs: Build Links with Images - https://ahrefs.com/blog/build-links-with-images/ ⭐️ Charles Floate's image SEO post - https://x.com/Charles_SEO/status/2021835662538813870 💎 Compact Keywords - My SEO Course - Get paying customers through SEO - Clear step-by-step video breakdowns - SEO templates to be copied and adapted for your products and services: https://compactkeywords.com/ 00:00 Image Backlinks Surprise 00:37 Dan Petrovic Experiment Setup 01:56 Results Image Alt Text Wins 02:27 Still Relevant Today 03:09 Link Worthy Image Ideas 03:42 TRUST Formula for Visuals 04:46 Outreach and Promotion 05:02 Stock Photos Backlink Hack 05:50 Reverse Image Search Links 06:28 Avoid Over Optimization 06:38 Optimize Well Find Great Keywords 08:55 Sign Off The Edward Show.
