Images – How to Optimise
How to Optimise Images
Image Optimisation became more important with introduction of Google Universal Search. Google Universal Search simply tries to combine the image, video, news, books, etc… results and present them together with the web search results. This is beneficial for the searchers as not only the web page text is considered when presenting search results, but other types of content as well. To mention some (potential) disadvantages - in some cases, half of the results on the first page are Google related/owned websites such as YouTube, Google News, Google Books and Google Image Search.
Anyway, why is image optimisation important?
At first, people do use image search for certain searches, so please consider, if your images are something they may search for.
Second, already mentioned Universal Search – images play more important role in web search. Image can provided additional information about page it is published on.
So what can be done:
- Use ALT (alternative) tag – use descriptive name, try to utilise targeted keywords. The main objective of using the ALT text is to provide a description of the image so if the browser is unable to view it, there is a text based description of the image (certainly benefitial for visualy impaired people using readers). Search engine bot or spider is kind of blind, not being able to see whais an image about, so you have to help it by using the ALT – alternative tag.
- Use Title for the image. The title appears when you hover over the image. Againg, this is something search engines can see.
- Use descriptive file name – image name. Image names can also help search engines to understand what is the image about.
If your site’s content is image rich and yourr traffic comes (could come) from image search, consider using text around your images. The text around the images is very powerful in giving search engines additional information on what is the image about.
