Washington ? The Republican National Convention is widely credited with giving President Bush a nice bounce in the polls. But what about www.GeorgeWBush.com?

The research firm Nielsen//NetRatings reported that traffic to the president’s official campaign Web site jumped by 50 percent during the week of the GOP convention. In the week ending Sept. 5, about 438,000 people clicked on his site from their homes — and spent, on average, six minutes and 24 seconds there.

Bush’s site, which the president mentioned in his speech accepting the GOP nomination, beat Democratic nominee John Kerry’s for the week. The firm said about 370,000 had visited www.JohnKerry.com during that period.

But Bush’s online bounce did not match his rival’s during the Democratic convention in July, when the Kerry site’s “a-home” weekly readership leapt to about 771,000 people.
