When you leave a comment on someones blog, it leaves them a link back to your profile for them to follow to visit yours. Nifty! But it doesnt count as a link for your blog -in search engine terms- because the templates most of us use, have a speck of code that prohibits that. How would you like to get around that?
Easy to understand instructions have been already been written by people more qualified than I am - so heres three links to get you started. Everything you need is on these three pages. Right, off you go then!
I follow at Randa Clay Designs
D-List at Courtney Tuttle
Removing 'nofollow' at Dummies Guide to Google Blogger
I do have comment moderation enabled, and I recomend that you do that too. We want to share links not spam. My comments policy is simple:
"Comments on this blog are made DOFOLLOW for the Google Spiders. Comments are moderated. Spam will not be tolerated."
That covers me from the spammers. With the comment moderation enabled, I have a chance to check out your blog before allowing the link to go live.
Yes folks! That means Im going to visit your blog if you leave a comment here.
Have fun on the net - and stay safe out there.
Aug 07 Edit: The comments policy is now displayed on the comment entry screen, and is worded largely the same as it is here - Cheers!
