A useful image answers a question. It might show a product detail, explain a process or help a customer recognise the service they need. Image SEO starts with that purpose, followed by a clear description and a file that loads efficiently.

For a small business website, a repeatable publishing routine is more useful than treating each upload as a separate technical project. Review the image’s purpose, description, size and placement before it goes live.

Choose a useful and honest image

Start by writing down what the visitor should learn from the visual. If the answer is unclear, choose a different image or consider whether one is needed. Keep illustrative scenes separate from evidence of real work: do not present a generated office or fictional installation as a completed customer project.

For example, a furniture seller could show a chair’s adjustment controls beside the section explaining them. A wide office photograph would provide atmosphere, but it would not answer the same question. Match the image to the information people need.

Name the file before uploading

Use a short filename describing the actual subject, such as “adjustable-office-chair-controls.webp”. Avoid a camera export name that means nothing to your team. Do not add a list of locations or services unrelated to what is shown.

Consistent filenames also make maintenance easier. Keep a record of the source image and its website version so a later replacement does not depend on finding the original designer’s downloads folder.

Write alt text for the image’s role

Alt text is a text alternative for an image. Describe the information that matters in its context, using ordinary language. “Height and tilt controls beneath an office chair seat” is more useful for a controls photograph than a repeated sales phrase.

Purely decorative images can use an empty alt attribute. An image that acts as a link needs an alternative that explains its purpose. Avoid duplicating a long nearby caption word for word. If a diagram carries important instructions, include those instructions as page text too.

Resize and compress with a visual check

Choose dimensions for the space the image occupies. A thumbnail does not need the same file as a full-width banner. Export an appropriate web format, compare the result against the original and inspect details such as product edges, small labels and gradients.

There is no single file-size target that suits every photograph and illustration. Try reducing size while keeping the details the customer needs. Check the page on a slower connection and a small screen rather than judging only the image opened on its own.

Make the image part of the page

Place the visual near the relevant explanation. Google’s image guidance covers contextual text, descriptive filenames, alt text and discoverable image URLs. An image sitemap can help discovery, but it is not a promise of visibility in image search.

  • Confirm the image loads from the published URL.
  • Check the alt text and surrounding explanation together.
  • Set image dimensions to help reserve layout space.
  • Use lazy loading thoughtfully for images further down the page.
  • Keep the original outside the public upload folder when only the compressed version is needed.

Finish by checking the article as a whole. The visual, heading and body should explain the same subject. For the wider page structure, see our guide to internal linking.
