5 Tips for Image Optimization in SEO Secrets Guide 2022

What is Image Optimization in SEO, Search Engine Optimization For Image

Image Optimization: In SEO content optimization, the thing that needs to be optimized is not only the relevance of the content to the target keywords and search intent, but also the images in the article. Without pictures in the article, your articles could be very boring for readers.

On the other hand, some things need to be optimized when you add images, such as image format, size, alt text, and copyright, to adding a sitemap image. The end goal is that these images can also be indexed by Google and help you attract traffic to your website through Google Images.

In fact, according to data from Jumpshot in 2018 via the Search Engine Journal, more than 20% of all website searches in the United States go through Google Images.

Then, how to optimize the image properly? Check out the tips below!

1.  Pay attention to the image format, choose JPG or WebP

When you want to include images in content, it’s best if you need to understand the various image formats that exist. Of the many formats, generally, several image formats are usually used for websites, namely PNG, JPG/JPEG, and most recently, the WebP format.

Generally, PNG is a reliable format because it has good image quality. However, this format has the potential to slow down your website because of its large size.

It’s different with JPG/JPEG. The JPG format is currently the most popular format on the Internet because its size is not too big with image quality that is still quite okay. The quality & size can be adjusted through photo tools, but the image quality will decrease the smaller the file size.

In addition to JPG, WebP is now becoming increasingly popular, because it is claimed to have a smaller size of up to 25% compared to JPG format images of the same quality. However, it should be noted that the WebP format is only fully supported by Chrome & Firefox. Only Safari users on macOS Big Sur versions and later can open WebP.

Of the three formats above, you must choose wisely before inserting images into your website. Because this will affect the speed of your website later.

2. Compress the image to reduce the file size

Before adding an image to your website, it would be nice if the image had to be compressed first to the size of the file.

Because, if the size is large, it will automatically make loading slower and the bounce rate will likely be high because it was abandoned by the user. As a result, this can reduce the Page Experience value of your website.

Therefore, do not be lazy to compress the image first. You can take advantage of various WordPress plugins that can reduce image sizes, such as WP Smush or TinYPNG.

In addition, you can also compress the image first via image compression sites such as picresize.com, ilovepng.com, compressnow.com, and many more.

3.  Add alt text to the image

Friends may be wondering, “where does an image in an article get traffic from ?”

The answer is to enter a description/explanation that is relevant to the image in the alt text. As mentioned at the beginning of the article, it is not uncommon for users to also search via Google Images.

When your image has alt text in it, then Google can understand the image, then index the image so that it has the potential to enter Google Images searches.

However, it should be noted also, that do not let friends spam keywords in the alt text. Don’t just enter your target keywords as alt text. As with the guidelines from Google, provide a caption that describes the image.

For example, you write an article about the profile of the Straw Hat Pirates from the One Piece manga/anime. Do not enter the alt text “straw hat pirates” into every image that is there, because that counts as keyword spam (entering keywords that have no relevance to the image, repeatedly).

Enter the alt text for example, “Monkey D. Luffy, captain of the Straw Hat Pirates” for the image of Luffy. Then “Luffy vs Kaido fight in Wano” for a picture of Luffy’s latest fight.

4. Don’t steal pictures, choose copyright-free ones

Friends, you are ready to optimize the image in the article by knowing the file, format, and alt text image.

However, you should not forget one thing, namely the copyright in an image.

Don’t let friends steal pictures without permission, especially those with licenses.

To be safe, you can search from sites that provide free photos, such as Pixabay, Unsplash, Pexels (DailySEO ID uses images from Pexels you know !), Freepik, and others.

If friends want to search for images via Google Images, you can use a trick like this:

  • Go to Google Images
  • Then, type in what keywords you want to search for images
  • Click the Tools box under the search field, then click “Creative Commons licenses”
  • From there, friends can use the image for free, because the creative commons license allows us to use the image (with credit).

5. Add an image to the sitemap

This method is also a powerful way for Google to index your images. That way, you can reap huge traffic from Google Images.

Friends can add images to the sitemap or create a new sitemap to accommodate images.

If you use WordPress, we recommend installing a plugin like Yoast or Rank Math. Both plugins offer good quality sitemaps.
