I have no problem with bloggers leaving their link in a comment on my blog, in fact I encourage you to do it. And when you do I don't mind how you leave it, whether it be just written out like this http://gemseren.blogspot.co.uk or as a clickable link like this GEM SEREN .
But when I leave a comment and a blog link, I like to leave mine as a clickable link as I think it looks neater, and Im a bit OCD with things like that.
So how do you do it? Its really simple, but for someone like me who has no clue I needed it spelling out.
Here is the code:
<a href="url">Link text</a>
And here is an example of how I would leave my link:
< a href="http://gemseren.blogspot.co.uk"> Gem x </ a>
I have left a space in between my < a and / a, this is so it would show up as text for the post. When you post your link remove the gap :):)
I hope this was helpful to some of you, I know it would have been for me, as I had to scour the internet to find out how to do this for myself haha
