Using images for Search Engine Optimization

I would really appreciate anyone’s help, and I hope you are able to understand my question. I’m new to E-commerce and I might not be using the correct terminology to explain my question.

First Image


Second Image


Third Image


I would like to use Search Engine Optimization in relation to my website I am developing by separating multi-word-named images.

When you have more than one image to link the same product, how do you optimize the second & third image without confusing the search engine?

Do you use hyphens for -2 & -3
Image: 1
elmo-onesie.jpg
Image:2
elmo-onesie-2.jpg
Image:3
elmo-onesie -3.jpg

Or would you use underscores for second & third image?

Image: 1
elmo-onesie.jpg
Image:2
elmo-onesie_2.jpg
Image:3
elmo-onesie _3.jpg

I would also like to clarify something else from the above question.

If you have to describe image to the search engine what would be the most appropriate way to describe the above image? Is there a limit on the amount of words you can use?

If you had to select from these examples, what would be the best one to use or would you use something else?

Example: elmo-onesie.jpg
Example: elmo-onesie-animal-onesie.jpg
Example: kids-elmo-onesie-animal-onesie.jpg

I have to hyphenate over 250 images and I would like to do this correctly the first time.

 

The example I'd choose is:
Example: kids-elmo-onesie-animal-onesie.jpg - as it seems like it'd have the best SEO affect... but I believe the alt text etc plays a bigger part than the file name.

As for the format for sequential images, that's a tough one - another for the table is like:
Image: 1
elmo-onesie.jpg
Image:2
elmo-onesie(1).jpg
Image:3
elmo-onesie(2).jpg

Considering this only as I see many programs name files like this automatically by default.

 

Iexo's reply seems to have a lot of weight. I have had good success with getting first place using the hyphenated (image-name.jpg) format of naming images. Add an extra keyword:

• image-name-keyword1.jpg
• image-name-keyword2.jpg

Good luck.

 

I would make them like this: $product_name-$descriptor-$number.png like the following:

• elmo-onesie-front-1.png
• elmo-onesie-side-2.png
• elmo-onesie-back-3.png

Then, add proper Alt and Title text to all of these images. And if your sitemap is smart enough you can have it add image information as well.
I would use some robot/tool to check my pages and if the e-commerce engine cannot make a dynamic sitemap, you'll have to use an external tool to make that as well.

 

Make sure the image file name is human readable and avoid over-optimisation. A good way to choose an image file name is to describe it in a few words: "Elmo kids animal onesie." You don't need onesie in there twice; once is enough for humans (in my view, anything that is pointless/meaningless/crap for humans comes within the realm of over-optimisation). So, the file name would ideally be "elmo-kids-animal-onesie.jpg" and an example of the alt text for it (remember, this is a description of the image; it is intended for accessibility) would be: "An Elmo animal onesie for kids in red."

When it comes to multiple images, I would simple do the following:

File name: "elmo-kids-animal-onesie-side.jpg"
Alt text: "An Elmo animal onesie for kids in red as shown from the side."

Remember to take advantage of structured data (check schema.org) for your products. This is now more important than ever for "SEO".

 

Specify image name in ALT Tag !!!

 

Do you actually understand what the alt attribute is for? It's an "alternative text" used by browsers/software that can't (or purposely don't) display images. It is to be descriptive and meaningful, not to stuff a file name in (although: it should be empty for images that are decorative).

Start here and read the references.

 

Images are important for showing products. Image optimization is needed for visibility of keyword in Search results.
We must give a image name with regarding product name and also we can add digits for makes it a unique.
I suggest we also add a brand name in Image name.
Example: [Brand Name]-[Product name]-[Digit].jpg
