How to Modify Your Images For Best SEO Rankings

Add Unique Images

Licensed Images From Shutterstock

Licensed Images From Shutterstock: Using licensed images will ensure no image copyright issues occur

There are millions of free and paid stock photos available on the Internet. But you can’t use them in your websites due to many reasons. First, it’s copyright. You can get severe problems if you use someone’s images on your website without their permission. If you think an image is in the public domain the best strategy is to credit the source and have a robust DMCA policy in place.

Can I Get a Search Penalty From Duplicate Images?

While Google can detect duplicate images, in general it is not good practice to use them if you can use original imagery instead. Duplicate imagery does not lead to penalties as with blocks of text, however:

If Google took a hard stance against duplicate imagery on web sites and blogs, what would happen with…

Recommended After Post Content?

Related content is everywhere and sure there are many sites using other sites’ images and/or infographics where the usage includes a link to the source. This is just a good practice Google can’t pursue.

Photographers and Digital Stock Photos?

Imagine you buy a picture from a digital stock library such as Shutterstock or a professional photographer. Of course you want to use it on your site. Penalty? Not going to happen.

Online Retailers and Affiliates?

So you have a ecommerce site where you sell a few brands’ products, and your brands provide you with official product pictures you decide to use. Would it make any sense to be penalized for using them?

Nevertheless what Google does now versus what Google does in the future can always change, once again always post original images within articles if at all possible.


To check for duplicates online or find websites that host various images, you can now do it via search by image

Rename Your Image To Exactly What It Is About:

Try to include the keywords you’re writing about at least in one image.

For Instance, if you write an article about “how to spend a good weekend”, in this case one of the images need that phrase in alt tag, and also for best practice keep the image name same as that phrase.

So, if your target keyword is “how to spend a good weekend”, then one of those images you used in your article need to be named similar to how-to-spend-a-good-weekend.jpg rather than using some other strange name or sequence of numbers.

Add ALT Attributes to Images:

ALT attribute is a short and complete description of your image. Also, for convenience, if the user has a slow internet connection or can’t view the image for any other reason, ALT attribute will help the reader to know what supposed to be there.

For the best SEO practices, the ALT attribute should contain your keyword or keyword phrase.

Check the HTML source code for the image with ALT attribute,

<img src=”how-to-spend-a-good-weekend.jpg” alt=”how to spend a good weekend”/>

Add TITLE Attributes to images:

The TITLE attribute is usually used for image title. When some put mouse on an image, image title will popup. Title attribute should contain the keyword or keyword phrase for best SEO and search engine rankings.

Here is the simple HTML code example:

<img src=”how-to-spend-a-good-weekend.jpg” alt=”how to spend a good weekend” title=” how to spend a good weekend” />

Note: the TITLE attribute is not going to improve search engine rankings just like ALT tag did, as the content provided by this attribute does not get cached in google and other search engines.

Use Relevant Anchor Texts On Image Links

For instance, if you have a separate landing page for the “extra small t-shirt”, the anchor text needs to be something like “extra small t-shirt for kids and babies”.

The above point will perform two things: first, it provides handy information to visitors; second, it provides proper keyword rich data to search engines bots.Here is the simple HTML code example:

<a href=””> <img src=”extra-small-t-shirt.jpg” alt=”extra small t-shirt” title=”extra small t-shirt”/> </a>

For anyone using WordPress, it allows you to insert images and other media, as well as specify things like ALT, TITLE, and description of the image. If you are using WordPress as a CMS, do take on board the benefits of that feature when uploading images.
