8 Tips to Optimize Images for Better SEO

Written by: Jason Bayless | April 17, 2017

1. Correct Image Size is Important – When selecting an image, you will want it to be the right size. The size specifications will be dependent upon your website. However, previewing a page can tell you if an image looks great or does not. Using images that are too small can look grainy and make your website look low-quality. On the other hand, using massively sized images can create long website loading times.

2. Choose the Right Sized Image – There is no magic number for the perfect image size. However, a medium sized image that is under 3 megabytes should be great for most web pages. Having correctly sized images saves you from editing and adjusting down the road. Businesses that work with smaller hosting companies can find large images quickly eat up their hosting space.

3. Use Clear Images – Finding medium sized images is great for most websites. You will also want to ensure that your images are clear. Previewing your website will let you know how it will appear to users. These previews are perfect times to see if images are clear. No visitor to a website wants to be greeted with grainy images that are hard to clearly see.

4. Compress Images – In addition to clear images, having fast loading pages is important. How do you find a balance between these two important concerns? Compressing your images will give you clear pictures and a fast loading website. Website speed is important for both visitors and search engines. It is common for many major search engines to list website speed as one of their ranking factors.

5. Naming Your Image – When saving your image, it is wise to give it a descriptive file name. Having clear file names ensures no confusion is created when working with multiple images. Also, clear file names ensure that search engines know what your images are about. Naming images properly saves you from headaches that are easily avoidable. The likely boost in rankings will help to ensure you always name images the proper way.

6. Include a Relevant Alt Tag – One important aspect of ranking a web page is having relevant alt tags. Alt tags are descriptive elements of an image that tells search engines what images are about. Unfortunately, search engine bots are unable to see a website image which is why alt tags are used. You don’t want to stuff keywords into your alt tags. However, placing some sort of combination of keywords and regular words is a great idea for most alt tags.

7. Use the Correct Format – There are different types of image files that you may use. Knowing the different types of images is important for any website owner. First, .jpg images typically offer great clarity and small image size. Next, .gif images are often used to create moving images and have a larger file size. Sometimes, .png files are great for images, as they have a small file size. However, the lack of clarity, when compared to .jpg, may not make .png the best choice.

8. Always Have an Image Sitemap – Yes, like your website has a sitemap, images have their own set of special maps. Most website editors have plugins where image sitemaps can be created. Many marketers prefer to use Google to create sitemaps for their website. No matter which image sitemap option you choose, it is always wise for your website to have these maps.”
