But it's a bit tricky. But before you go out and solicit links to your site , know that Google considers more than vote volume. It considers which sites give you votes. Votes given by pages that are themselves important are worth more and help give other pages a higher ranking. President and co-founder of Google, Sergey Brin, says this eliminates most spam from Google's index.
Few webmasters link to sites that have a reputation for spamming.
Excite indexes Web pages as users see them, so your pages' meta tags, which aren't visible to users, aren't as important as their titles, body text and link relevance. Excite's algorithm measures sites against the concepts described in users' searches. So, to optimize your site for Excite , keep unrelated topics out of your main pages. Excite's spiders miss most of the formats AltaVista's do, such as database-driven pages and PDF files. If you want your banners to sell better, visit BannerTips.
