Image Filename:


Creating descriptive,  better selection keywordis absolutely crucial for image optimization.  Search engines not only crawl the text on your webpage, but they also search for keywords within your image file names.


Don’t use the default camera name example SAM IMAGE25, try select the better name related to your content (While naming Don’t  use just one word to name your image files ) write few Description  about  the image.


For example if you are writing about the samsung mobile write fully about the samsung model name, colour , features, rate  etc    i.e In camera name they set default as GMIMAGE 45 you must select better name as Samsung Galaxy S3 GT-I9300 white color 2014 .


While people search in the search engine using the terms

  • 2014 white colour Samsung Galaxy S3 GT-I9300
  • Samsung Galaxy S3 GT-I9300  2014
  • white Samsung Galaxy S3 GT-I9300  2014


Your product will display in the search engine,be sure to use good keywords when naming your images.


Uses dashes/hyphens not underscores or pluses, to separate the words in the filename i.e  Google sees dashes as word separators, and underscores as joiners

 

For example

  • Back-link     denotes    Back link
  • Back_link      denotes    Backlink


you should place your images in one folder on your site, mydomain.com/images versus placing them in random folders throughout the site.

you use common image filetypes such as JPEG, GIF, PNG, and BMP.

 

Alt tags:


The Alt tag displays the best part in image optimization factor.  Alt denotes  alternate.   The text in the alt tag is displayed in place of the image if the image can not be shown or is taking too long to load.

Most of the major search engines are text-based, i.e they can not read images and videos.  Don’t leave the space empty in the image location


These empty spaces are not in any way good for your overall SEO.  The alt tag  informs it about the topic of your image.


Because search engines can’t read images, you need to use alt tags to help describe your image.


If you have an image of the child in rain , your alt tag should read something like this:

 

Alt=”girl child enjoying safely  in rain with umbrella”

 

girl child in rain with umbrella

child enjoying safely in rain with umbrella

 

The key to creating good alt tags consists of three points:

  • Image needs a proper description, without keyword stuffing.
  • If you sell products that have model number or serial numbers, use them in your alt tag.
  • choose the better keyword
  • short and correct to spot out keyword
  • don’t use alt tags for decorative images.  Search engines may penalize you for over-optimization.

Upload load faster images

 

Select the correct t image file format. Don’t use GIF file format unless your image is an animation.  Use PNG file format instead.  Because PNG image file  size  is 20% smaller than the same GIF image file.  Another advantage of PNG  is  the PNG can be saved up to 24 bit whereas GIF can be saved only as 8 bit.  you get more color depth and higher quality image with same size in case of PNG.  It uses a lossless compression which means no image data is lost when saving or viewing the image.


JPEG uses a lossy compression which means image loses quality and information each time it is saved. JPEG file size almost always smaller than a PNG.

i have the variation of the  sizes of a 162 X 203 resolution image in various formats:

  • JPG, 60 quality =====> 5.658K
  • PNG-8, 256 colors ===>15.31K
  • GIF, 256 colors ==.=>= 14.73K
  • PNG-24 colour =====>22.8K

While uploading the image you have to notice few more factor.


Crop out extra white space around your image and use CSS to create padding around the image.


Specify width and height for all images. These dimensions can speed up page loading.


Use image optimization tools like smush.it , skitchDynamic Drive Online Image Optimizer ,Picnik you can adjust the dimensions, while keeping the storage size small through compression.
