A picture speaks a thousand words.
A image on SEO must speak. In my last three works I made a different consultancies for costumers and I detected the same issue: the images.
The images are always forgotten. And Google likes images and users also.
Let’s start a list of best practices to keep in mind.
3 Basics Tips SEO Images:
1. Name of images.
I found images like DSC30303 or Screenshot22.01.2009 or Prueba or Slider-home.png
The images needs to BE descriptive.
It’s important to add relevant keywords also. If we review analytics we could see how customers search us and use to te image naming process.
Example if the image is a green car:
2. File size
I discovered 3GB for a Background image.
Bear in mind:
- The consumers do not like wait unless in mobile.
- Google uses page load time as a factor in their algorithm.
So review the file sizes, compress the images and optimize them.
The formats are rellevant also use :
- GIF, lower quality than JPEGS used to icons, transparency, animations.
- PNG, the alternative to GIFS, allow transparency more colors. But the sizes are bigger to JPG. PNG is better used on flat and colors images.
- JPG: able to compress images considerably, could have nice quality and low file size. Not transparency allowed.
3. Alt atribute
The alt atribute is the alternative text is used to:- highlight the identity of an image
- appears when browsers have problems rendering
- read by screen readers to help visually issues
- read by search engines
That’s a normal code that I discovered:
That’s a good code:
<img src=http://exampleweb.com/images/green-car.jpg alt=”A green car on the road”>
The alt atribute is also a descriptive text for the image, normally we use 8 words.
