Accurate Alt Text
Written for someone who cannot see the image. That is also what makes it useful to search engines.

Image SEO Services for Pages Their Images Are Slowing Down
Images do two jobs in search: they can be found themselves, and they usually decide how fast the page feels. Image SEO covers both — alt text and file naming that make an image findable and accessible, and format, size and loading decisions that stop the largest image on the page from being the reason it fails Core Web Vitals.
Alt Text Describes the Image, Not the Keyword
Alt text stuffed with keywords helps nobody and is read as what it is. It should describe what is in the picture.
Dimensions Always Set
Width and height on every image, which is the single most common cause of layout shift.
Format Chosen Deliberately
AVIF and WebP where they suit, and not where they do not — social preview images being the usual exception.
Loading Decided Per Image
Lazy loading below the fold, never above it. Lazy-loading the LCP image makes the metric worse.
Measured
Payload measured before and after, because image work is easy to do and easy to overstate.
Image SEO, Explained
How Do Images Hold a Page Back?
Three ways, and the first two are usually the largest performance problem on the page.

Oversized Files
A 2,000-pixel image displayed at 400. The browser downloads all of it and throws most away.

No Dimensions
Without width and height the browser reserves no space, so everything below jumps when the image arrives.
- 3
Alt Text Missing or Written for Robots
Either nothing at all, or a keyword string that describes nothing. Both fail the reader and the crawler.
What an Image SEO Engagement Covers
Performance and findability together — they share most of the same fixes.
Sites Where Images Are the Payload
The heavier the imagery, the larger the return.
Ecommerce

Portfolios and Agencies
Image-led sites where the pictures are the content.
Real Estate
Listing galleries, which are usually the heaviest pages on the site.
Publishers
Where image search is a real traffic source.

Questions,answered.
Image SEO covers both making images findable — accurate alt text, descriptive filenames, image sitemaps — and making sure they do not slow the page down through oversized files, missing dimensions or wrong loading strategy.
What is in the image, as you would describe it to someone who cannot see it. If a keyword genuinely belongs in that description it can be there; if it does not, forcing it in makes the alt text worse for everyone.
No. Images below the fold, yes. The image above the fold — often the LCP element — should load eagerly. Lazy-loading it delays the very metric you are trying to improve.
AVIF is usually smallest, WebP is more broadly supported, and both beat PNG or JPEG for photographs. The exceptions are social preview images, where some platforms do not decode modern formats, and logos, where SVG is often better than any of them.
They need an empty alt attribute — `alt=""` — which tells assistive technology to skip them. Omitting the attribute entirely is different and worse: a screen reader may then read the filename aloud.
