You’ll have heard of alt text as many bloggers tell you this as a freebie, alt text means ‘alternative text”.
It’s not that secret an SEO tactic.
There are may people that use a screen reader through loss of sight for example, the screen reader tells the person what is in the image. If you have not filled out the alt text field and used a sentence to describe the picture so that a human can make sense of it then the screen reader will make up its own version which may not make sense at all.
Alt text uses:Moz
1. Adding alternative text to photos is first and foremost a principle of web accessibility. Visually impaired users using screen readers will be read an alt attribute to better understand an on-page image.
2. Alt tags will be displayed in place of an image if an image file cannot be loaded.
3. Alt tags provide better image context/descriptions to search engine crawlers, helping them to index an image properly.
Google can not read pictures – YET!
Alt text is also a great place to enter your keywords so another possibly source to rank yourself. Many bloggers will have told you this but how many have said be natural? Don’t keyword stuff your alt images! It looks spammy!
Correct Use Of Alt Tags
- Be as descriptive as possible but keep it to 125 characters, describe the picture and what is in it but don’t add unnecessary words.
- Include your keyword “phrase” if it’s relevant to the image and hopefully you’ve chosen something relevant.
- You don’t need to state it’s an image in your alt description – they already know it’s an image!
