Image SEO Checker

Image SEO on a page means every informative image has alt text and files are not heavier than they need to be. A missing alt is an empty alt attribute. This table illustrates those issues without fetching the page.

Image SEO on a page means informative images have alt text and files are not heavier than they need to be. A missing alt is an empty alt attribute. This table illustrates those issues. The summary counts are part of the fixture.

Total is one of the values Image SEO Checker puts on screen. How many images the audit saw. The total is a sample count. It is not the number of img tags on your page.

Read Missing alt on its own before you mix it with the other rows. An informative image with empty or absent alt. The sample marks some rows missing alt. Those filenames are not your assets.

Large size answers a narrower question than the headline number. A heavy file slows the page. The sample flags a size without downloading the file. Compress from a real byte size.

Treat Healthy as a label with a specific job. A row with alt text and a modest file. Healthy is computed inside the fixture. Do not report the healthy count.

The Source column line is worth a full stop. The image URL. The sample fills sources. They were not scraped.

A large-file flag in the sample uses a teaching threshold, not a measurement of your bytes. Audit real alt text by reading the alt attribute on each img in the live HTML.

If you remember one sequence from Image SEO Checker, remember the fields in the order they change a decision. Total matters because How many images the audit saw. In practice, The total is a sample count. The mistake to avoid is this: It is not the number of img tags on your page. Missing alt matters because An informative image with empty or absent alt. In practice, The sample marks some rows missing alt. The mistake to avoid is this: Those filenames are not your assets. Large size matters because A heavy file slows the page. In practice, The sample flags a size without downloading the file. The mistake to avoid is this: Compress from a real byte size. Healthy matters because A row with alt text and a modest file. In practice, Healthy is computed inside the fixture. The mistake to avoid is this: Do not report the healthy count. Source column matters because The image URL. In practice, The sample fills sources. The mistake to avoid is this: They were not scraped. After that, the checks are simple. You did not write alt for sample filenames. You did not report the counts. You did not compress from the large flag. Decorative versus informative will be decided on the real page. The live img tags are the next read.

The worked example for Image SEO Checker, read as one scene, is this. Type https://example.com/story. The table lists images, alt notes, and counts. example.com was not fetched, so a missing-alt row is not one of your pictures. View the live HTML and read alt on each img. Compress files whose transferred size is actually large.

Final notes for Image SEO Checker, written as decisions rather than as a table. When Total is in front of you, decide using this: How many images the audit saw. It is not the number of img tags on your page. When Missing alt is in front of you, decide using this: An informative image with empty or absent alt. Those filenames are not your assets. When Large size is in front of you, decide using this: A heavy file slows the page. Compress from a real byte size. When Healthy is in front of you, decide using this: A row with alt text and a modest file. Do not report the healthy count. When Source column is in front of you, decide using this: The image URL. They were not scraped. Then apply the checks without skipping one. You did not write alt for sample filenames. You did not report the counts. You did not compress from the large flag. Decorative versus informative will be decided on the real page. The live img tags are the next read.

Keep Image SEO Checker as this step only. When the job moves on, the Image Alt Text Generator is the next page: Image Alt Text Generator writes three alt sentences from a description and a keyword you type. The Image Filename Generator covers a different piece of the same work: Image Filename Generator turns a short description into a lowercase hyphenated file name.
