For your homepage go to Settings and click General Settings
On the page shown there should be a text box labelled "Slogan" Edit the box and whatever you put in here will appear in the heading of your browser when you are on home page. Also, try and keep the characters (including blanks) less than 85 - apparently Search Engines don't look further than that and don't like longer tags.
Also, avoid "and", "to", "if", "the" etc these are seen as "dead words" that stop teh search engine from looking beyond them.
For the other pages - go to Contents/Catagoties >> Datasheet View. This will bring up your list of pages. If you click and enter one of the pages you should see box headed Title - it appears that whatever you enter here will appear in the Browser header as mentioned above. Once stick to guildines as mentioned around number of characters etc.
There's a great book i bought called "Search Engine Optimization - An Hour a Day" Jennifer Grappone and Gradiva Couzin. They also point you to their website which is also full of resources, worksheets, actions etc. and accompanies the book well.
It's not as easy as they make it out but a lot easier than others, plus you can save the few hundred pounds a month the SEO "experts" want to charge you. You should be able to make small changes which will keep optimising your site bit by bit.
Don't try and do everything at once. Pick one thing/topic at a time and just do that bit.....
Good luck...
