How to Optimize Images for Search Engine Rankings
Photos can generate loads of search engine traffic from the Google image-based search engines.
Image Alt Text
Presently, search engine spiders cannot recognize “the subject matter of an picture.” Instead, they rely on the “Alt Text.” Therefore you must help Google understand each of your images by placing a text description within the alt text of each picture.
Use your keyword phrase in one or two instances of “ALT text” on the page. To include it, you simply add
alt="this is your alt text" to your image tag.
Image File Size
Page load time is crucial! People are going to wait a mere second before they back out of a site that is not loading quick enough.
So bounce rate is the factor you need to weigh with regard to pic size. Make your media file sizes as small as possible (to be visible on your website).
Use Adobe Photoshop or an Image Optimizer to adjust photo sizes. [A large, quality picture should be around 70kb and a picture image at around 20 – 30kb].
Image File Name
Before you upload your photos to a website page, pick a descriptive & keyword targeted file name – it will boost your Google Image Search Engine rankings.

High ranking photos nearly always have the keyword you searched for in their file name.
There’s no direct relation between image captions & search engine rankings. However, because they are one of the most well-read pieces of content on your site, Image Captions can lower your bounce rate.
- A bounce rate over 70% is considered a high bounce rate [bad].
- Bounce rates under 50% [good].
- Bounce rates as low as 40% or 30% [excellent].
