Rename my frontpage page 2 on url

Hello,

I have 9 posts on my front page but I dont want to increase the amount to 12 or anymore (because of seo - it would mean me having more than H3 headings on the frontpage). So the limit is 9 and it's got a 2nd page with the remaining 6 posts. My question is please how do I rename the url http://www.xxx.com/page/2/ to something a bit more seo friendly.
