Welcome to part 3 of our multi-part series on constructive search engine optimization practices.
In my last two blog entries, I discussed strong content writing and Web page titles as ways to build search engine optimization for your website. Today I’ll discuss optimizing images. Everyone loves a good image because it can add something special to your story and make a positive impression on readers. I like using them to add humor to my posts and visually describe what my post is about.
I’ll use the image above to illustrate good ways to optimize your images. By the way, I love cats, just like I love movies, and that’s why I’m using a picture of kittens. If you put your mouse over the image, you’ll see a caption pop up that says “Three kittens from the same litter snuggle together for a nap.” That is the image title or caption.
If you right-click the photo and hit the “Properties” button, you’ll find additional information that is used by search engines, like Google, MSN and Yahoo, to “see” what is in the images. Search engines are blind, so you have to spell out exactly what is contained in an image for them to notice it. One way I optimized this image for search engines is by providing alt text, which appears when the image does not load properly. This helps people who are unable to see the image to know exactly what it is, and it also helps search engines at the same time. By adding relevant, succinct alt text, like “Three sleeping kittens,” you are that much closer to optimizing your image.
The location of the file is www.eharborinc.com/blog/images/2009/0
2/sleeping_kittens.jpg. There are a number of lessons to learn from this file name and location. The file is in a specific folder that is meant only for eHarbor Blog photos. If every image’s file was located in a different place, it would be more difficult for search engines to go through and find them. It’s much better to have a good organizational system in place.
Most of the files we use in this blog are in JPEG format, but you can also use GIF, PNG or BMP to store your images. I find that JPEG is effective for my purposes, but each format has its own strengths and weaknesses, so you should pick and choose the format as your needs change. Also, keep the name short and simple. Don’t use generic names like “Image1.” I used “sleeping_kittens” because that pretty well describes the image.
This is the third part of this series. We’ll cover several other ways to achieve SEO in upcoming blog entries. Check out Google’s SEO Starter Guide for more information on this topic. The photo of the kittens is from Flickr and it is the copyright of Gúnna.
