How to Bulk-Insert SEO-Friendly Alt Text for All Images on a Website

Images boost engagement — but without alt text, they’re invisible to Google and inaccessible to users. Writing alt text for hundreds of images is boring and slow. With Summrly, you can generate SEO-friendly alt text at scale. Just upload your images or enter your topic, and AI will create descriptive, keyword-rich alt text for every image — improving accessibility, image search rankings, and overall SEO.

Why a Content-First Website Solves This

Most websites leave alt text blank or use generic filenames like “IMG_1234.” Summrly starts with your topic and uses AI to understand image context — then generates meaningful descriptions like “woman doing yoga on beach at sunrise” instead of “yoga.jpg.” This helps Google index your images, improves accessibility for screen readers, and boosts your chances of appearing in image search results.

Step-by-Step Guide

Create Your First Topic – Enter your niche (e.g., “fitness coaching”) to set the context for image descriptions.
Set Up Your Content Focus – Choose your audience and image type (lifestyle, product, infographic).
Add Keywords – Include relevant terms to make alt text SEO-friendly.
Brand Details – Add your brand voice so descriptions match your style.
Complete Setup – Generate and export AI-powered alt text for all your images in bulk.

Enter your topic below to generate SEO-friendly alt text for your images — and make every picture work for your SEO.

Case Study: 300 Images, 1 Hour, 4X Image Search Traffic

A travel blog with 300 untagged images was missing out on visual search traffic. They used Summrly to input their niche (“budget travel in Europe”) and generate alt text for every photo. AI created descriptions like “backpacker exploring old town in Prague” and “affordable hostel kitchen in Berlin.” After adding the alt text, image search traffic increased by 400% in 8 weeks, and the site appeared in Google Images for 80+ keywords.

FAQs

Can I upload multiple images at once?
Yes. Bulk-upload images or provide URLs for AI to analyze and describe.
Is the alt text accurate?
Yes. AI analyzes image context and generates relevant, descriptive text.
Does it include keywords naturally?
Yes. Keywords are woven in without stuffing — e.g., “hiking boots on rocky trail” for a footwear site.
Can I edit the alt text before using it?
Absolutely. Review and refine any description to match your needs.
Does this help with accessibility?
Yes. Clear alt text improves experience for visually impaired users and screen readers.

Summary

Alt text isn’t optional — it’s essential for SEO and accessibility. With Summrly, you can generate accurate, keyword-rich descriptions for every image in minutes, not days. No more blank alt attributes. No more missed image search traffic. Just enter your topic and let AI make your visuals discoverable.
