Write descriptive alt text-  When you start writing alt text make sure it describes the image well so the user understands it fully.

Keep it short-  Always ensure that your image’s alt text must be small as well as have a full description. There is no need to create large sentences.

How to optimize the images?

 Choose the right image format- Google Images supports images in BMP, GIF, JPEG,    PNG, WebP, and SVG formats. 

JPEG (.jpg) is a standard format of the image as images of this format compressed easily with a high-quality result of the image of a small size. JPEGs are SEO-Friendly.

GIF(.gif) format is used for animations as it does not require a wide color range. It is maybe safer to use a true video format for large and long animated videos.

PNG(.png) produces images which are of better quality but comes with large file size.

WebP(.webp) as it produces high-quality images with smaller file sizes.

SVG is used in making logos and icons. For eg, you can handle images in SVG format with the help of CSS or JavaScript without loss of quality.

  Resize your images – Properly resizing the height and width of the image is a necessary factor in image optimization, which most bloggers overlook.

If you upload an image in your blog post and resize it in the post editor itself, whenever the browser loads this page, the image will first be loaded in the original dimension and then it will be resized. This will increase the loading time of your page.

Whenever you download an image, its dimension (Height & Width) can be more, which is necessary to resize before uploading to your blog. You can resize the image in the computer with the help of Paint tool or Photoshop. 

Create Unique Design –   Images when used with care help the user to better understand your article. 

Do you want your photos to stand out on the website?

 If you need images for your article, then you cannot use Google Images. Those images can be copyright protected and they can later run into trouble for you.

There are many websites in the market that offer free stock images. You can use a website that gives images for free and is related to your article and there is no other option to draw your created image.

There are websites like FreeDigitalPhotos, Freepik, Pixabay, Pexels, etc. which provide stock images for free. Apart from this, you can easily get high-quality and professional images on Shutterstock by spending some money.

  • The more original images you have, the better the user experience and the better the chances are about ranking on related searches.

Choose the dimension of your images

  • It depends on your theme and article. Although the content area of most blog themes is 600- 700px. So, you can use the image dimension as per your theme.
  • It is a good practice to define the height and width of your images, either do it while you are creating it or you can do it with CSS as well.
  • If you upload these images in your article without resizing and resize them in the post editor, then you are on the wrong track.
  •  Reason: When your article is loaded in the browser, the images will load in the original size and dimension. As a result, your site’s load time may be impaired.
  • You can use the plugin or online website to resize the image.

Reduce the file size of your images

  • If you use high-quality stock images in your article, it can put a lot of load on your server. That is to say, the size of the high-quality image is also very high.
  • Try to keep the size of your image within 100kb. If the image size is above 100kb or in MB, then it clearly shows that the image is of high quality. Always resize such images and upload them with the correct dimension.
  • WordPress.org has a lot of image optimizer plugin that can help resize and compress your images. 

Beware of decorative images – How to affect on the website and what effect.

Decorative photos do not add information to a page’s content. For instance, the information provided by the image could already be given using adjacent text, or the image could be used to make the website more visually attractive.

Decorative images are used to beautify the site. They can result in large file sizes combined with slow load times.

You should check the size of all the decorative images on your website and try to make sure that they are at least in size.

Here are some tips on how to reduce the size of decorative images:

  • Instead of using images, use CSS to construct colored areas where possible.
  • Render them PNG-8 or GIFs for images that make up borders or simple patterns.
  • Look closely at that big background image in the form of a wallpaper. Those files can be massive. Shrink as much as possible, without ruining the quality of the image.

Rename Images

  • Before uploading the image in a blog post, please rename it according to the keywords. 
  • When you download an image from a website, its name is something like “45abc.jpg or 3hd@.png”. Such file names are not search engine friendly.
  • While renaming the image, use the main keyword in it. By having the keyword in the image, the search engine ranks it much better.

For instance – If you are writing the article “How to rank number one in google 2018”, then the name of the image will be something like “rank-in-google.png” or “rank-one-in-google.jpg”.

Always write the name of the image in small letters and use dash (-) in between every word.

Choose the right image matched to your content

  • Always keep in mind that whenever you are adding images on your site, images are always related to what the content is about. Using unrelated images is a waste of time.
  • Do not link to unrelated images from the post and the search engine also does not know for which purpose you are applying the image.
  • Using the image in a topic when you are unable to convince the user,  is a very good way to explain your point.
  • Always name your images according to related content, it is a best practice according to Google.
