When you are adding a photo, video, diagram, cartoon etc. to your business website or company blog, you need to add text to the file. The main reason for this is simple: this text lets search engine algorithms assess what the image is, so you can use the photo to help increase your page ranking for specific search terms.
Also, some computing devices may have images disabled, and this text gives the user an idea of what the photo they cannot see is of. Lastly, a caption can make the image more interesting or fun, or even explain the meaning if it’s not easily identifiable within the article’s context.
This is simply a name you give to the image as a whole. Meta titles for website pages come up at the top of the browser, but meta titles for images just let the search engine ‘spiders’ know exactly what the photo or video is about. You should use SEO (Search Engine Optimisation) keywords here if you can, but make sure you stick to explaining only what the image is.
People who for whatever reason have images disabled on their computer will still be able to see this text. People often disable specific types of media in order to keep their computer running as quickly as possible, or when they are on a notoriously slow broadband internet connection speed. Some very old computers also have trouble ‘seeing’ certain files.
Having ‘Alt Text’ ensures these users know what type of visual information they are missing out on. This is another chance to sew valuable SEO keywords into the back-end of your website, but again make sure you don’t stray from the truth when explaining the image.
Here’s your first opportunity to list as many SEO keywords related to the image as you can. In this instance, it’s perfectly fine to go on tangents and add terms you know people are searching for in relation to your business, as well as the exact words describing the media file.
For example, you may have a photo of a small ladybeetle sitting on a green bush, but the reason you have chosen the photo is to express the importance of creating an identity that stands out online. Someone else may use a similar image to describe his or her gardening business. You would list keywords like ‘brand identity’ and ‘unique online presence’, and not just ‘ladybeetle’.
This is usually the most enjoyable text to write for an uploaded image or video file. You can be creative, as often the meaning you wish to convey from the image is totally different from the normal context of the content. You are welcome to use keywords here too (as people can actually see this text), but the main idea is to make the caption interesting.
Another form of text that readers cannot visually see, these terms and phrases are a great opportunity to use a wide range of related SEO keywords for the algorithms to crawl through. Write about what the image file is, what it means, how it relates to your business, and what your business does. Be very descriptive!
Remember, slapping an awesome photo or video onto your website or blog can excite viewers, but if there’s no text attached, the image will not affect your search engine page ranking at all. A picture speaks a thousand words…but not in terms of quantitative SEO keyword value.
