While it’s not always necessary to include images in your posts doing so adds interest and eye appeal. Also when it comes to bringing search engine traffic to blogs, images do that. Even if readers do not like your posts, image searches can bring your blog hits. This post contains tips for SEO of images.
SEO for images
The Google crawler cannot read image scripts and therefore using the ALT attribute (providing a description) will allow you to tell the crawler what the image is referring to. If you want your images to be indexed by the search spiders then give your images the full treatment (TITLE tag, ALT tag Description).
Without a TITLE tag, no ‘hover text’ will show up when the mouse passes over your image. Hover text is a useful way of letting your readers know what’s in a picture.
Without an ALT tag, Google will likely fail to index your images correctly according to the keywords you want, because those key words have not been provided. In other words, if you do not provide a description, you are depriving your images of possible hits that could have come if it had been used and had included key words.
Also note that it takes up to 6 months for Google image search to find your pictures, but it will miss your pictures altogether if you don’t use ALT tags and Title tags correctly.
Additional SEO tips for image optimization
- Surround your image with pertinent text.
- If your image isn’t unique (i.e another instance in Google index), then resize it so it will look different for search engines.
- Use high quality images only and the SERP thumbnail will have a better appearance.
