When writing about a product or information elsewhere, ensure people know what you are referring to. Your words will then make sense, especially if you are giving instructions or reviewing the item in question.
For example, I just read an email that said “Just go to the very bottom of the page and find my items” There was no link and there were no items listed at the end of the email, so I had no idea what page I should be looking at the bottom of!
If you are sending an email and referring to a particular product, webpage, article or whatever, include a link to it or attach it to the email. That way people are not confused and don’t have to waste time trying to find what you are writing about.
Likewise, if you are writing in your blog or on your website, add links to your products, articles and testimonials instead of referring to them and letting people find the information themselves. For example, my article about clear communications may give you more information about why to include a link. But are you going to search for it? Much easier if I say the article is available by clicking on this link, isn’t it?
