How To Write Good Alt Text

A computer keyboard in the background. How To Write Good Alt Text written over it in blue text

Hello everyone. When I started my first blog many moons ago I had no idea what all the technical terms ment or how to write good alt text. I simply wrote shit (and yes for the most part my old posts really were shite) and pressed send.

Fast forward a couple of years and I began to take more of an interest in the technical side of blogging. I learnt about keywords, SEO, picture resizing and very basic coding. There were still a lot of things that I didn’t  understand. But my blog seemed to function quite well without me knowing what they did, so I left them alone.

One of those things was the alt text. I knew there was an alt text box there when editing pictures, but couldn’t see how it benefited me or the blog. So I always left it blank.

Alt Text and Pintrest

I first used  alt text when I discovered Pintrest. At the time I was using and didn’t know how to make my images pinable. After searching Google I found that adding the post title as alt text for an image made the image pinable.

However there’s no need to do this. The alt text wasn’t designed to help bloggers share posts to pintrest. And  the share button options on WordPress and Blogger now include a Pintrest button.

Alt Text and SEO

I began using alt text more when I became interested in improving my SEO. SEO for those who are not up on their blog speak stands for search engine optimization. It relates (I think) to how likely a search engine such as google is to find  a post and list it when someone searches for the subject the post is about.

I  was using the SEO help plugin Yeost. One of the things Yeost says to do to improve SEO is put keywords into the alt text. This is because the alt text is read by search engines.

Now while it is true that keywords within alt text can improve your SEO this is also not its prime function.

What is alt text designed for?

Alt text  actually stands for alternative text, and that is basically what it is. It provides an alternative to the image in a post. Alt text was designed for people who have sight problems and rely on text readers to access the internet.

I’ll be honest,   I was quite ignorant about the real importance of how to write good alt text until very recently. I became aware of it after following a thread in a Facebook blogger group. A certain blogger (blogger A)  said alt text did not aid SEO, so should not be included in a post. A  blogging friend of mine who uses a text reader politely pointed out the real use of alt text. Blogger A stated images were just used to pretty up a post and  blind or partially sighted people didn’t need to know what was in the images.

Now obviously this view is bollocks and very discriminating. But actually by not including alt texts in my posts I felt I wasn’t a lot better than the blogger A. So I’ve made a conscious effort to include alt text in all my new posts and to gradually go back and include it in old posts.

How to write good alt text

So, we arrive back to the title question. Alt texts obviously need to describe what it in the picture. But how to write good alt text?  I am a waffler (you may have noticed) and could write a paragraph on each picture but that isn’t going to be very useful. The key is to put a  brief but accurate description. Keywords can be used in alt text but only if they fit the description of the picture.

I’ve add a couple of pictures  with the alt text copied into the caption box. So people can see examples of how to write good alt text descriptions.

A wall in chepstow castle. Three arch doors at ground level. A wooden stairs leading to a third door. The sky beyond the wall is bright blue

A medieval room with a vaulted roof. An arch doorway at the far side of the room leading outside

As you can see the descriptions aren’t hugely detailed, but enough to give people using text readers an idea of what the image is.

I’ve written this long rambling post because I suspect a like me a lot of bloggers won’t be that aware of the importance of good alt text for blind and partially sighted people. But  like me they will be happy to use it once they are aware of its importance in aiding everyone to enjoy their posts fully.

Were you aware of how alt text helps people  with sight problems access the internet? Will you be more inclined to use it now?

    I’ve only recently become aware that there is such a thing as alt text! I try to add it but I really don’t know what I’m doing, so this post is very helpful! #abitofeverything

    I’ve been trying to be sure to fill in my alt text box with descriptions since I learned of its true purpose! Thank you for pointing this out to everyone. #abitofeverything

    I must admit I didn’t care much about this when I started out in January either but the more I blog, the more I research and read about things I can do to improve the SEO. Alt Text is so important and I do it for every post. Maybe not as well as you’ve done it above. I must make more effort and go back one day and re-do all of mine. #MixItUp

    Pretty awesome information, luckily I have a very techno geek husband who helps me with it all! I’m still learning the basics, so some days I think my post is mint and others I think it’s naff, but it’s all a learning curve, that and SEO

    I am quite frankly ashamed at how rubbish I am at doing this even though Sassy explained it all to be perfectly. I am going to give myself a good kick up the arse and do it from now on. thanks for the reminder. #mixitup

    About a bazillion years ago when the internet was new and slow, I used to teach PageMill (one of the earliest web design programmes for Apple). Iniitally alt text was helpful in that it allowed people to understand there was an image and what it was if it didn’t download, it made it quicker for people to scan websites. However I was only made aware of how felpful it is to visually impaired viewers earlier this year from a visually impaired blogger too. It’s wonderful how softwear has come on so far that information can be read out loud from a computer too. #mixitup

      It is wonderful. I still worry about how well I write my alt text, but I always add it

    This is something I’m really bad at, I have started doing it more but definitely need to be more consistent with it and go back through some old posts too. Really helpful post.

    Ah, I knoew it was for decribing the picture, but I had thought of it more in terms of if the picture doesn’t load for some reason (which has happened on occasion). Hadn’t considered the visually impaired aspect – thanks for pointing it out, I will make more of an effort in future. #BlogCrush

    I had no idea about this, thanks so much for enlightening me! I do remember at a blogging conference one of the lecturers did tell us that we should describe the image and not use the post title, which makes total sense now. I’ll definitely be writing my alt texts differently now!

    This is a really useful post Tracey and I’ve been using alt text incorrectly for nearly two years. I’ve always been post title in there, oh well, at least it says something. For my next post, I’ll think about the alt text a little more. Thanks for linking up at #fortheloveofBLOG. Claire x

    I have used alt text since I started my blog. Where I thought it was a pain sometimes I have seen the benefits of doing pay off and can see in my “geek” stats that I have consistent hits through Google a couple of years later on certain posts… fairly early on though I met a blind blogger who is now a good friend and she convinced me that even though a pain to do sometimes it’s totally worth it for a bit of inclusivity. It’s become habit now to add in some
    Alt text to the point i can’t not do it!
    I love awareness posts like this for bloggers!! #familyfunlinky

    Thanks so much for this post! My blog is largely focused on communication and accessibility issues, and I didn’t know about this! I knew a little bit about image descriptions, but I haven’t taken enough time to learn how to write them properly. This helped me learn how important they really are and how to write them properly, so I am now able to add a new level of accessibility to my blog.

    I saw the original thread about this and tried to improve mine too when I did the pocket money toy box reviews. Great guide, I thought mine was a little rambly but I think reading this mine should be ok-ish 😂 #familyfunlinky

    I had no idea that this is what alt text is for! I only knew it to be for booting SEO, especially when everytime I try to put that little dot above my post in the green and it says the pictures don’t display the SEO word in alt text. This is really good to know. I will try to remember to do this with my pictures from now on:) #ablogginggoodtime

    Really helpful – I think I’m probably not writing enough in my alt text given your examples. They are usually short like ‘Boy on beach’ or such like. Thanks for your examples. #ablogginggoodtime

    I have to admit I am terrible with alt text – a lazy blogger who just pastes her keywords in there shame on my name! This is a great post on how to do it properly. Thanks for linking up to #coolmumclub xx

    This is really helpful – thank you! I do wonder about how accessible my blog is and I’d like to improve it but am not entirely sure where to start… I do use the alt text box but possibly not in the best way.

    Well done for raising awareness of this. It was only recently (After becoming disabled and connecting with other disabled bloggers) that I discovered what alt.text was for. I do try to remember to use it all the time now. I don’t have sight problems but there are people out there who do and why shouldn’t they know what’s in the picture? Brilliant post x

      I have hearing problems myself and I know that without subtitles I cant enjoy films and programs. So I understand how it can be to not have something you need to help you access something x
