Images are one of the basic requirements for a good dynamic website, which also helps improve the SEO factor of our website through Google/Bing Image Search.
Well optimised images act like a second gate (first gate is obviously through the content) for viewers to enter your website via Image Search. Thus it improves the chances of increasing the traffic to your website.
I have seen many wordpress users, who do not pay attention to the images section in the wordpress’s image dashboard; probably because they don’t have much idea about how beneficial this feature is for optimizing their website from SEO’s point of view.
Before we move forward let me give you a checklist for optimising your website accordingly for images.
- Images should be smaller in size and should not be big in dimension
- Images when uploaded, there metadata should be filled properly with the right target keywords in it (discussed later in this article)
- Images smaller in sizes reduces the site-load time of a website, which is a major factor of consideration by google and other search engines these days
- WordPress users can use various plugins that can help you in optimising as well as in reducing the image sizes accordingly.
Let us first discuss what WordPress offers us for the image’s search engine optimisation :
The image uploader in WordPress provides four boxes which can be intelligently used along with your target keywords.
Image title does the similar thing that the page title tells the search engines about.
The title of the image is auto-generated from the file name you had saved on your computer (Which can obviously be changed). Rather than leaving your images named “Image_1.jpg,” rename it with words that describes your photo the best.
For example if it is your logo give it a name something like “logo_YourcompanyName.png”
Try to do the same with all the other 3 boxes.
Caption is the text that is visible below the pic in smaller font, which tells the viewer about the picture, sometimes also used for giving picture credit.
3. Alt Text
Alt Text is the name visible to viewers when either they have disabled the images in their browser or the images somehow fail to load.
Use your target keywords here.. along with the words describing your image.
Image Description is similar to “page meta-description” which tells the search engine about the image briefly.
“Title”, “Description” and “Alt-Text” are the most important factors from SEO’s point of view. And the most important keywords should be used in these three boxes only for getting better results.
Apart from these four boxes for image optimisation, there is one more thing wordpress enables us to do is the use of image optimisation plugins.
So let us discuss the Image optimisation plugins free/premium that can boost your site speed as well as Search Engine Optimisation.
