The other morning I was checking my Linkedin feed for no specific reason at all, other than its a great B2B platform and I stumbled across a great little video on image optimization for SEO. This got me thinking, when was the last time I did any ground level SEO leg work on our work website? Probably months ago. So like the gym, I love doing cardio, strength and conditioning work but I’m not loving leg day ever. That’s a lie. I like doing leg day but I just don’t love doing it.
So I thought I would share how I go about doing some leg work on SEO for images. According to the video, images sizes on your website should be <50kB. This will help you speed up your website’s load time and Google is really looking favourably on this at the moment. Secondly, all images should have Image Alternative Text Tags which should describe the image in plain english e.g. A Photo of The Copper Coastline. This is so search engines can crawl your info/keywords better and in turn help you get up the rankings.
Here is how I do the leg work for image sizes:
- Download Screamingfrog app.
- Run the SEO Site audit for your website.
- Export the results.
- Open the CSV file in MS excel
- Apply a filter to the topline.
- Sort by largest to smallest image size. The cut off is 50kB. Anything over this could do with replacing.
- Use an image compressor for PNG files. I used this one. And Google Picasa for compressing Jpegs.
- Replace and delete the larger files.
I was horrified to find one logo PNG image that was 400kB! So after I compressed it became 5kB. So thats an awesome result. Imagine over a website how much load time you can save…probably not that much but it all helps thats what I like to tell myself.
Screamingfrog will also give you the statistics and results for the Alt Tags again making this easy but you have to put in the leg work.
Final tip. JPEG is okay for your website but PNG is better as it compresses a lot small in size without losing too much quality.
And don’t skip SEO day!
