Did you know that even the images on your website will have a effect on where how well the website is ranked on search engines? There are some best practices for website images which are covered here.
Save images for search
Search engines can instantly recognise what an image illustrates if it is saved in the right way. The file name is an essential part of optimisation for search engines.
Save the image according to the subject matter of the photograph.
I.e. Saving an image as <strawberry-cheese-cake.jpg> is more informative and effective than <image07_912.JPG>.
Search engines will recognise the effort.
Google quality guidelines ask website owners to ‘place images next to relevant text’ where possible. Make sure that any images you use are relevant to the text.
Once you have resized, compressed and saved your image correctly you are ready to add it to WordPress.
