Image and Video Development for SEO

Visuals do three jobs for an SEO business: they make pages easier to understand, they can rank in image and visual search, and — when they’re original — they earn links and shares. This guide covers creating visuals with AI and Canva, the technical basics, and how to build a visual system that makes your brand recognizable.

Creating visuals with AI and Canva

I'm writing an article on "[topic]" for [audience]. Suggest 6 visuals that would genuinely improve understanding (not decoration).
For each: type (diagram, annotated screenshot, chart, illustration, checklist graphic), what it shows, suggested file name, and alt text under 125 characters.

File naming

File names are a small but easy signal. Use descriptive, lowercase names with hyphens.

Alt text that helps people (and search)

Alt text describes the image for people using screen readers and gives search engines context. Write for humans first.

• Describe what’s in the image and why it’s there, briefly.
• Include a keyword only if it naturally describes the image.
• Skip “image of” or “picture of.”
• For charts, summarize the key takeaway (and explain details in the text).
• Decorative images can use empty alt text so screen readers skip them.

Compression and formats

Heavy images slow pages, and page experience matters to users. Compress everything.

1. Resize first. Don’t upload a 5,000px image to display at 800px.
2. Use modern formats. WebP is widely supported and usually much smaller than JPEG or PNG. AVIF can be smaller still; check your setup supports it.
3. Compress. Use an image optimization plugin or tool; check visual quality after.
4. Set dimensions (width and height) to prevent layout shifts.
5. Lazy-load below-the-fold images; don’t lazy-load the main hero image.
6. Test with PageSpeed Insights. Run the SEO Audit Tool for a quick check.

Image sitemaps and indexing

Google can find images in your page HTML, but image sitemaps can help it discover images it might otherwise miss. Many SEO plugins include images in your sitemaps automatically.

• Use standard <img> elements (images loaded only via CSS backgrounds are harder to index).
• Place important images near relevant text.
• Make sure image URLs aren’t blocked by robots.txt.
• Submit your sitemap in Search Console.

Original graphics as link bait

When other writers need a visual to explain something, they look for one they can reference — and often link back. Create the graphic your niche is missing.

Infographics that still work

1. One idea only. The best infographics answer one question.
2. Tall for Pinterest, wide for articles. Make variants for each channel.
3. Accurate data only. Cite sources in the graphic and on the page. Never invent numbers.
4. Add the text version on the page so search engines and screen readers get the content.
5. Promote it: Pinterest, newsletters, and outreach to writers covering the topic.

Build a brand visual system

A consistent look makes your content recognizable across every channel.

• 2–3 brand colors plus neutrals
• 1–2 fonts (headings and body)
• A featured-image template for blog posts
• A thumbnail template for video (Video SEO)
• Social templates for quotes, tips and carousels (Social Media SEO)
• An illustration or photo style guide (e.g., “flat illustrations, warm colors”)

Video development basics

Visual systems extend to video: consistent intros, lower-thirds, caption styles and thumbnails. Keep them simple so production stays fast. Descript and CapCut handle captions and edits; Canva handles thumbnails and simple motion graphics. For the full workflow, see Video SEO.

An image SEO workflow for every post

1. Plan visuals with the outline. Decide where a diagram, screenshot or chart would make a point clearer.
2. Create or capture. Screenshots and your own data first, Canva templates second, AI images for illustration.
3. Name the file descriptively before upload.
4. Resize and convert to WebP (or AVIF if your setup supports it).
5. Upload and write alt text in plain language.
6. Add a caption where it helps — captions are often read more than body text.
7. Set the featured image and check how it looks in social previews.
8. Repurpose the best visual for Pinterest, LinkedIn and your newsletter.

Here are descriptions of 8 images on my page about "[topic]": [list].
For each, write: an SEO-friendly file name (lowercase, hyphens), alt text under 125 characters written for screen reader users, and an optional one-line caption. Only mention the keyword "[keyword]" where it genuinely describes the image.

Visual search and social previews

Images also get discovered outside classic image search. Google Lens lets people search with a photo, Pinterest recommends visually similar pins, and every link you share shows a preview image.

• Use clear, well-lit product and location photos so visual search can recognize them.
• Set Open Graph images (most SEO plugins handle this) so shared links look intentional.
• Create tall pin versions of key graphics for Pinterest.
• Keep your logo and brand colors consistent so people recognize you in any feed.
