Optimization for images is most important for SEO. Search engines are getting smarter day by day. So in order to get a good ranking, we have to meet maximum criteria.
Normally, we focus on best content and ignore the image SEO but we have to be very careful with image optimization.
I am sure about one thing: Not everyone is very good at reading but one can see the content and understand. You should keep your content available for both type of users
“Images explain million of words in a glimpse. Videos are even faster way to get noticed”
1. Image relevancy factor
A relevant image always helps Google to rank you better.
If you are using an image of an apple connected to a post related to book reading app doesn’t make any sense.
If you want to tag an image of an apple then you should check if you are talking about apple as a fruit or mobile.
2. Importance of Alt Tag
Alt tag is basically a way to describe the image to Google. For example:
(img src=”apple.jpg” alt=”Apple mobile”) So here Google will understand that we are talking about ‘Apple mobile’ because Google cannot see the images.
Alt is an abbreviation for ‘alternative’ so instead of an image, Alt tag will describe the nature of image to search engines.
Alt tag should be descriptive and detailed. For example, if there is an image of the elephant eating the banana, Alt tag should be (img src=”elephant-eating-banana.jpg” alt=”black elephant eating a banana”)
So more information will make an image more search engine friendly. This will dramatically improve your image SEO.
3. Image size matters
The size of the image plays an important role in image optimization. Because this impacts the load time of the page and eventually user experience.
If it’s taking more than 8 seconds your potential subscriber will fly away and also increase the bounce rate of the website.
If you are using WordPress, you can try wp smush plugin.
This will help you to reduce the size of the image at the time of upload or you can do bulk smushing.
4. File name factor
The file name for the image should be relevant. I have seen people make this mistake quite frequently.
For example: If I have an image file as “20151222_203605.jpg” this won’t give any information about the image to search engines. So rename it with valid description and use proper Alt tag as discussed in point #2
5. Don’t use generic images from search result or stock images
Many of us are so focused on content that they don’t want to spend time on image creation.
Best image selection can help you rank higher in the search result. Mostly we prefer some low-resolution image or generic stock photos.
You must have seen some very nice and clean image on one blog and while searching for same keywords you will realize that the same image is being used at many places in different context.
Now when Google crawler will come to search these images it won’t provide relevant information.
For example below image from Shutterstock can be used in various ways. So I will always recommend using the image which makes more sense with your content.
See how Shutterstock named the same image: stock-photo-relaxed-woman-arms-rised-enjoying-sun-freedom-and-life-an-a-beautiful-beach-young-lady-feeling-429852457.jpg
6. Don’t steal images
Sound rough? But I am sure many of us are knowingly doing this just because they don’t want to spend time in producing good images.
Copyright can be the major challenge for people stealing images and photoshop the watermark.
If it’s difficult for you to buy images or create an image, you can refer to the site providing high-resolution images. Find the link below:
Hope these links will help you. You can pick the most relevant images as discussed above instead of a generic one.
7. Improve image quality for best SEO
Once you have downloaded the image from unsplash or gratisography use some image editing tool to enhance the quality and make it relevant to the post.
Photoshop can be very helpful but I would recommend using some other tools. Because for using photoshop you need certain skills to understand the tool and it can take a lot of time.
I used canva and YouZign and so far they are best for such image optimization.
I am sure this will take a lot of effort but it worth investing time in image optimization. Visual content always gives a better understanding.
