Nothing sets off a really great piece of writing like a couple of eye-catching and appropriate images. They grab the attention of your reader and flesh out the details of your carefully written posts. But when it comes to adding adding tags and titles, consternation can arise quickly. The key to optimizing images for search is to add descriptive, accurate information that helps readers AND search spiders understand what the image is about. Are you optimizing correctly? Below are a few tips that will help you learn how to optimize images for search.
As an example, let’s take a blog post written to celebrate the life and times of Bob Marley, which displays his likeness holding a guitar.
First, make sure the image is a reasonable size. Massive images clog up your load time – keeping the image under 100KB is generally a safe bet. The most search-engine friendly format for an image is a jpeg, so save your file accordingly. When you do, give it an accurate and descriptive filename, separating keywords by dashes (NOT underscores.) A good choice might be Bob-Marley-playing-Guitar.jpg.
Once your image is uploaded and placed in your post, you want to be sure your keywords are near the image in the body of your content. This should be easy: it only makes sense to include an image of Bob playing his guitar if your post is already about that.
Next consider the technical aspects of the image. There is much misunderstanding about the difference between the alt attribute of an image and the title attribute. The alt attribute, or alt text, is intended to provide information to visitors who are otherwise unable to view the image. The title attribute provides additional information. Keep these two bits of information short, accurately descriptive, and different — they should not match exactly. Use the key phrase you are shooting for in the alt text of your image, and include a synonym or slight variation for the title of the image, perhaps “Bob Marley playing guitar and singing”. If you include a caption, this is another great opportunity to mention your key phrase or a variation of it: “Bob Marley on stage in 1976 playing his guitar.” Title tag, alt text, and caption should all be separated by spaces.
Now take a look at your robots.txt file. Are search engine spiders allowed to access your images folder? If not, remove the line that says “Disallow: /images/” from your robots.txt file. Finish by stepping back and reviewing your work to be sure you have not been inadvertently guilty of keyword stuffing. Don’t use keywords where they aren’t critical (“Bob Marley reggae performer playing guitar while singing reggae song Buffalo Soldier reggae legend” might be overdoing it just a dab.)
And there you have it! What issues trip you up the most when optimizing your images?
