One way is using subdomains, if appropriate. e.g. you have a shopping portal and you can add new affiliate merchants as separate subdomains.
I loaded a new subdomain on 27/3 and today I noticed from my logs that its pages are coming up in Google searches, just a week later. This is a record for me.
I have not used trusted feeds but the other option would be to get a link from a frequently crawled page.
That's like saying you can get new pages indexed quickly by having steak for dinner! ;) Just because you had steak for dinner last time your pages got indexed....
The only factor on how quickly your pages get indexed is how often your site gets crawled.
If you want to get your new pages indexed, then make sure they are linked to from top level pages in your site and Googlebot will find them as soon as possible. There's not a lot else you can do to force the situation.
The more regularly you update content (particularly Homepage), the more frequently Googlebot will visit. But that's a longer term solution and doesn't help right now - your site is being indexed x times per month and there's not a lot you can do to increase that in the short term.
It's not the steak! It's the double gin on ice you have with it!
I think the only way to speed it up is to get more incoming links, also to the deeper pages. And high PageRank links definately help to get the site indexed in a few days.
How about links to the new site that come from sites that resolve to the same IP as that new site? :)
As long as you get a few decent incoming links(PR4-7) to target pages whether they are internal links or from the same IP blocks or not, the target pages will be crawled and indexed within a few days.
Ranking is different story, though. :)
Would ranking be affected by links from another site on the same IP?
Links - any links - will help your site get indexed only because it enables Googlebot to find your new site.
PageRank doesn't help your site get indexed faster. The only way it may seem to help is that a high PR site is likely to be crawled more frequently as they are larger and probably adding regular content.
More inbound links won't help your site get indexed faster (well, more inbound links mean more chance of Googlebot finding your new content sooner, but chances are that any link will get your site indexed soon enough).
Links from the same IP range - do have an impact on ranking - it is debatable just how much of an impact they will have though (probably less impact than links from other IPs).
Match your page name exactly to your title tag and your description tag. If you don't believe me, ask Google for any search terms and you will see your search words highlighted in the page name, the title tag and the description tag. Google now reads these tags and uses them to determine relevance. I do not even use the keywords tag. Now, it takes a LONG time for G. to get the re-done pages into the SERPS. In my log, I notice that Googlebot has only visited ONE of my re-done pages in the last two months, and I have tons of re-done pages. I think it takes 8-10 months to pull the pages to the front of the SERPS, but I have re-worked all my pages so they have this match-up. I noticed this when the VERY FEW Google searchers would find a page on my site, I saw that this matchup was the reason. Yes, I work on links, yes I have good fresh content. Google hits? ALMOST none...Site almost 1 year old, maybe still in sandbox, but the OLD inadvertently matched up pages do get to the front of SERPS. That is how I learned this...hope this helps...
