A short list of things that I do
Technical stuff
1) always update my sitemap
2) check the new links for title and alt in chase of image links
3) new links are always on top of the old ones.
4) test every new page in each of the three browsers IE/Firefox/Opera
Marketing stuff
1) the new updates are part of my weekly newsletter
2) the menu from the main page is updated always with the new links
Hope to be useful,
