There are several websites that provide a huge number of images that you can use (with attribution or a link back to the website, of course). For example: FreeDigitalPhotos.net, FreeImages, FreeFoto.com. For example, FreeDigitalPhotos offers smaller web-sized images for no charge, while you can also order larger formats for a charge.
Use keywords which provide imagery to your article or blog post. Think outside the box, use some visual terms in order to find the best pics.
One pic is good but, for longer articles or blog posts, two or three can be a better choice. The more images you use, the more additional opportunities you get, so you can optimize your piece better, which results in drawing more traffic to it.
These are four of the most popular optimizing tips you should try with your images. Make your next post more likeable and shareable! You won't even notice how your readership will soar!
Captioning – Keep in mind that your caption should speak to your article or blog post you've written, not the image itself. Therefore, make it rather brief but, at the same time, descriptive.
Alt Text – One of the best ways to maximize your search engine content is through adding alt text. The trick is that Alt text gives to your article or blog post another SEO layer. This is because Alt text describes the image to Google, or any other search engine. Try adding it to your image text. I't quite simple, all you have to do is: alt=“image description for alt text” and it's done.
So next time when you sit down to write another article or blog post, take a minute or two to pick out some images, optimize them correctly and enjoy watching your traffic roll.
