Increase brand awareness: Customers will be impressed and sympathetic with photos that help satisfy search needs and have watermark attached (website or brand).

Prepare and optimize images

Find & select photos
Images, you need to find a source of quality images and suitable for the content. Preferably copyrighted. This is a picture you took yourself, designed by yourself.

In case you have to use photos from other sources, you must find a place that ensures quality and reputation.

During the image preparation process, you need to do the following:

+ Fix poor images: If your photos are not sharp, it is usually because the photo is at a low resolution. Photos are underexposed, or flared, these things make the image not beautiful and you need to fix and edit the photo before posting it on your website.

Fix poor image

+ Replace images unrelated to the content: If you have a beautiful image that is not related to the content, it is not so good. So you need to find and select relevant images that explain your content.

Choose the Correct Picture Format
Currently there are many image formats for you to choose from such as PNG, JPEG, GIV, SVG, WebP… and PNG and JPEG are the most popular formats for the web.

PNG: Produces a better quality image but has a larger file size.

JPEG: You can reduce the image quality, but you can adjust the quality level to find a good balance.

GIV: optimized animation

WebP: high compression ratio, but still preserve image quality. However, this format is only supported on some web browsers.

Today, all photo editing software can let you save photos in a variety of formats. Or else, you can use online tools to convert hidden images to different formats.

Introducing some free website format conversion websites such as:

Create unique images
Everyone wants the images on their website to be attractive and unique, but not everyone can. And most websites copy each other’s images.

So you need to create a unique image by adding other images or adding text to add animation. Take for example the thumbnail image of this article.

Another thing is that you are the creator of that picture, if you are not good, you can hire media units, they specialize in taking pictures, designing images according to your requirements.

Name the image file
You should name images that are good for SEO. And the image name should follow the phrase that describes the content of the image. Vietnamese should remove accents and separate them with a sign (-), not put a sign (_) or write them together.

For example, as in this paragraph.

Do: you should name the image: dat-ten-cho-hinh-anh.jpg

Don’t: image-12.jpg or name it image.jpg

Also you can put by the main keyword of the article. In this article, the main keyword that I mention is: Image SEO optimization, you can download image files with the name: toi-uu-seo-hinh-anh.jpg

In short: Depending on the context of the article, you can name the image according to the content you intend to insert. Or you can name the image after the main keyword, or the title of the article.

With this naming of images, Google and other crawlers understand the subject and content of the image.

Determine the image size
Usually when you download images, the large size might be 1024 × 1024. Although the right size for your website is 600 × 400, you should also resize it accordingly. If you upload with a large image size, increase the file size, reducing the page load speed.

So before uploading images to the website, you should determine the appropriate size.

Another thing is that when you post many photos in an article, you should keep the same size for balance, should not let small images, large images look unprofessional.

The problem of resizing images, you can refer to the tools available right on your windows or mac computer. Those are Paint and Mac Preview. In addition, you can refer to the online tool pixlr.com, which supports free image size customization.

On Windows select Image -> click Edit -> Paint-> Resize and choose the size as shown

Optimize images on the page

Optimize image ALT attribute
Alt tags are an alt text for images when the browser cannot represent them correctly. Similar to the title, the alt attribute is used to describe the contents of the image file.

Alt text is the text that summarizes the content of the image, placed within the <img> tag with the syntax alt=”Image description”. Alt text (alt text) means alt text, which will be displayed on the web page in the event that the browser fails to load the image for some reason. You can see the example below, if the image in this article fails to display, it will display the text as alt.

So you need to optimize this tag in image SEO. Besides describing him when the image is not displayed, it is also the content that helps Google read and understand what the image is and what content it contains. And will help that image rank high on the rankings.

Create Titles, Title tags for images
The title=”” attribute acts as a tooltip that appears when the user hovers the mouse over the image. See illustration below.

You try to point your mouse over the image above, you will see the title

This attribute does not affect SEO, but if you use it, it still helps improve users better, so it also indirectly benefits your web SEO.

Add captions for photos (caption)
This is a caption usually located at the bottom of a photo, to briefly explain what the image is about. You will see your uploaded images have a caption right below the image.

Why is this important for image optimization? In fact, in an article, the title almost clearly states what the content of the article is. And for users, they often read the caption when surfing the content.

Statistically, captions are read on average 300% of the content. So if you forget to use it properly, you are missing out on user interaction.

In the past, I myself often did not pay attention to this, but with the following articles, I myself have made notes for the image more fully.

Responsive image
You’ve heard a lot about responsive, mobile-friendly, including SEO and web design. The same goes for images.

You can use the srcset=” ” attribute in the <img> tag so that the browser correctly selects the smallest sized image that fits the mobile screen size. Small image size means reduced page load time, which means Google optimization.

Reduce image file size or Compress images
But as mentioned above, reducing the image size will make your website load faster. And what if a customer visits your website but the loading time is slow, they will be frustrated leading to a decrease in purchase behavior.

So you need to compress your images before uploading. You can use photo editing software like Photoshop, Cesium.

Or you can use plugins like TingPNG, WP Smush. These are plugins that automatically compress images without losing image quality. You can refer to other image compression plugins, I only recommend 2 plugins that I often use.

If your website is a new website, you should compress images before uploading, if your website is old, before you have not compressed images, use a plugin to compress all images. And after using the plugin, your website will improve the page loading speed.

You can refer to Google’s PageSpeed ​​Insights tool.
