The images and photos on your blog or website can be helpful or or hurtful to your site’s overall Google ranking. The goal is for them to be helpful! Things to keep in mind include photo size which can effect your site’s load time and whether or not your images are optimized with the appropriate Alt Tags/Text and Titles.
So what are Alt Tags and why are they important? Well, they’re not really tags, they are more like descriptions. According to Yoast, the SEO experts, “Alt tags and title tags strengthen the message towards search engine spiders and improve the accessibility of your website.”
So let’s break it down. This is a complete HTML image tag:
If you’re using a visual website builder, HTML is the text “behind the scenes” that tells your server what to display. Most website builders have options for viewing and editing the HTML directly, but to add your Alt Tags and Titles you shouldn’t need to. In fact, if you’re using WordPress, adding your Alt Tags is easy. After uploading your photo simply click “edit” and you’ll see these options.
If you’re using another platform you will have similar options. I suggest finding your image options or settings where you should be able to add the same things – Captions, Alt Tags/Text and Tool Tips. The Alt Tag/Text is what appears by default when you Pin an image to Pinterest. If you enter something in the Tool Tips field that text will appear when someone hovers over the photo on your website.
Now that you know how it works, let’s talk about what your Alt Text should include. Just like it’s important for your site Title and page Titles to include keywords and phrases, your Alt Tags should do the same. Alt Tags should be a full sentence or phrase that describes what the photo is all about or why it’s on your site. Yoast also recommends that “If your image is an image of a specific product, include both the full product name and the products product ID in the alt tag, so it can be easily found.”
Now that you know how to optimize your images, go back and edit the photos on your site that don’t have custom Alt Text and be sure to add it to any of your new photos and images in the future. SEO is always changing but this is a tried and true method to make your website more Google-friendly.
