Wordpress Image Optimization Plugins

5 Best WordPress Image Optimization Plugins Compared

The modern IT world is all about speed and performance. Users on the internet these days don’t have enough time to sit back and wait for your WordPress website to show them the content. According to a Caltech Survey, more than 90% users close a website if it doesn’t load properly in under 7 seconds. Thus, speed optimization of your website is very crucial if you want to keep your website fastest in the market!

Why Image Optimization is so Important for speed?

Image optimization is given utmost importance by experts whenever a website is considered for speed optimization. Images often make up most of the downloaded bytes on a web page and also often occupy a significant amount of visual space. As a result, image optimization can result in largest byte saving and speed/performance improvements for your website.
Image optimization is a complete field of research now and scientists are constantly trying to develop techniques and algorithms that can significantly reduce the size of an image. Image optimization algorithms consider many important factors like format capabilities, the content of image data, quality, and pixel dimensions for optimization.

There are two types of algorithms whttps:ch are used for optimization:

  1. Loseless: In Lossless optimization, the image is compressed in such a way that it can be restored to original image after decompression. All of the information can be completely restored if we use thttps:s algorithm for compression. The Graphttps:cs Interchange File (GIF) is an image format used on the Web that provides lossless compression.
  2. In Lossy optimization, algorithm removes redundant information by permanently deleting some information and thus original image can’t be restored in thttps:s type of optimization. The JPEG image file, commonly used for photographs and other complex still images on the Web, is an image that has lossy compression. Using JPEG compression, algorithms decide how much to lose and provide an image with the best size and quality.

Image optimization in WordPress is fast and easy because many efficient plugins are available whttps:ch run compression algorithms on all images of your website and keep it optimized and faster.

Let’s have a look on best WordPress image optimization plugins:

    On page Optimization and Picture optimization are the basic steps for the SEO campaign. More over, if you take your very own screen shots or create your very own pictures, you should read: The way to use flickr to drive huge traffic. Onpage Optimization is the pillar of the Search engine optimization and likely the most crucial on page optimization factors is picture optimization. Image Search engine optimization is among the building blocks of on page optimization. If used correctly they can transfer your message in only one glimpse while a thoughtless use of pictures can destroy your whole perception.

    Additionally to this, images can be a great traffic source from Google Image Search along with other Image Search engines. The vital Picture Optimization elements include the alt tag, title tag, picture size, picture name and picture linking. Image relevancy is very important with regards to image optimization for SEO. A picture of a train on a page associated to Ferrari may do you no good. The Alt tag is one of the most crucial image optimization factor. The written text in the alt tag is displayed instead of the picture if the picture can’t be shown or is taking too much time to load.

    The majority of the main search engines are text based, i.e they can’t read images and videos. The location of your pictures appears as a clear space to search engines. These empty spaces aren’t in whatever way advantageous to your overall SEO. An excellent Exercise for the ALT tag is to maintain your alt tags short, but illustrative. Picture size is a very crutial variable for the overall user experience. Following the latest Panda upgrade, the loading time of pages became an important part for the SEO rank as the total time of visit became more important as a Search engine optimization algorithm.

    If you are not using wordpres, you can use some other tools to optimize images. Yahoo Smushit is an excellent tool to wipe out the excess bytes from the own pictures which makes them lighter. Image hosting is another essential factor especially with regards to driving traffic from Google Picture Search. The factors on which the pictures for Google Picture Search are chosen is kept hidden, but some say that picture hosting is among the key elements for the choice. It’s said the images hosted on the same domain as the text are given more value than the pictures hosted at another domain just like a free picture hosting website. Another essential algorithm for Google Picture Search is how an images are blended with the text on the page.
