In the first instalment of better SEO, I discussed the importance of content in your webpage. This tip will focus on how to optimise images for better SEO.
When we see an image of a woman smiling, we instantly recognise what is going on in the image. However, a search engine spider or a screen reader cannot see the image, they only read text.
Our ALT text (or alternative text) must describe what is happening in an image.
Before uploading your image to the web server, make sure you pick a descriptive name, something that you want to rank in a search result for. This will help to show your image in an image search and it will also help with your overall search results for the page.
A recent article from Moz.com shows the importance that page load speed has on search engine results. Images file size plays an important part in the load time of your page. It is important to resize and size images correctly before using them on your page.
If you do not have Photoshop or another image editing program, there are plenty of other, free online services that allow you to resize and crop images, including resizeyourimage.com.
Do not upload a large image and rely on HTML width and height values to resize it, this technique keeps the same file size for the image. The end user still downloads the full image and the browser resizes the image into the given values.
That's all for now. My next instalment will appear shortly. Let me know what you think or if there's any particular topic within SEO you would like me to cover.
