How to Optimize Image for SEO
There are some simple but basic steps and tips for Website Image Optimization which are as below:
1. Use the Right Image
You must use at least one image in your website page, blog or article. Image must be relavent to the page content. This create a first impression about website content so this must be of good quality and informative, not abstract. You can find many good free images from flickr, FreeImages, New Old Stock, Unsplash and etc. You must make sure before uploading an image that it is not the copyright of any one, otherwise google can mind.
2. Descriptive File Name
Keywords are important for images just as in URL so, before choose and upload your image, use short and descriptive keyword rich file name. File name should be relevant to the image so, avoid using file name like “DSC0023.jpg” as it never gives relevant information about the image to user.
Avoid by writing excessive long file name with stuffing of keywords, this will make it spammy. Try to use 2 to 5 words for naming the file and separate them by using underscore or hyphen.
3. Alternate (Alt) Text
Just remember alternate text is your friend and most important factor in image optimization.
Many search engines like Google cannot read the images and videos because it’s a text-based search engine so, alternate (Alt) text is displayed if image taking long time to load or cannot be shown. In simple words Alt text uses to understand images by search engines. Alt text should be of some words instead of entire sentence.
4. Relevant Alt Text
If you don’t want to confuse search engines then make sure that you are using relevant Alt text for images because it’s important for SEO.
Basically an image of a flower will never go with the page related to birthday cakes. Due to any other reason if image would not display on browser, users could get it with the help of Alt text so, it should be relevant to image.
5. Image Caption
Caption matter just like an Alt text with short keyword because it’s a cutline text that appear below the image. Caption can also be defined as it’s a detail about image that what’s happening in photo and displayed below the image for SE and visitors.
6. Image Linking
Avoid linking your images directly; it’s one of the basic tips. If you write any link below the image then Alt text becomes its anchor text. Always write Alt text when using images as a links but never use only image link for site navigation and upload so many images that it would be then an image page not informative website to visitors.
It is also effective for SEO when posting images on other sites or pages to get a link back to your site or page.
7. File Size of Image
Time taken while uploading a page really matters for SEO and visitors, viewer will never like it if your site taking time to open and uploading images this will bore them. Image size is a very serious factor for user’s experience, if your webpage take more than 10seconds to open then forget about traffic and good ranking from SEO.
- Here are some simple ways to reduce the size of image
- If your image is of large size then crop it to the correct size of your page width.
- Color depth should be reduced to lowest at acceptable level.
- If you want to a big size image then show a smaller image by providing an option of “view large image” in a pop-up.
- Experts say: that image size should be below 70kb.
8. Common File Types
Most of the browsers support only JPEG, GIF, PNG and BMP image format, so it is recommended to use this extension. SEO highly recommend using JPEG file type as a first choice and after that PNG as second.
Let’s see which file type is used for right image
JPEG - Image are able to compressed, as a result image quality of image is good but with small file size.
GIF - These are low quality images as compared to JPEG and its used simple images such as decorative images and icons.
PNG - Images becoming popular because it’s an alternate of GIF’s and it support more colors than GIF’s.
BMP - Is an image with a raster graphics format which is used to store digital images.
9. Responsive in Webpage
Sometime, we post high quality image which is larger in size and it gets out from the content border and it seems very negative to users. In latest update, google includes mobile friendly pages in his SEO Ranking Factor so Image must be optimized and responsive for Mobile Phones.
10. Site Map for Single Directory
Making a site map for images is good but not necessary so, store your all images in single directory rather than spreading image files out in many other directories or sub-directories. This will help you stay organized behind the site.
If you spend hours and days on writing a perfect web post, then don’t miss a chance to optimize your images for more and more benefits of search engines. All mentioned step would help you a lot longer than a few minutes.
