Thread: SEO question

Hi have spent a few hours looking through the forums and have come across a couple of things that have got me confused!!
Came across SEO advice that said to add robots tag on page and put the file in your root on your server and submit to webmaster tools.
What is a robot tag, what is it for, and how??
Also what does "use title attribute for anchor links" mean?
And one last question(for now anyway,haha) it says "make sure your page code is less than 100KB", how can you check that?

Well have answered the robots query myself through other peoples threads but am still stuck on on the page code and "use title attribute for anchor links"? any answers would be appreciated!!
