I have found reading about search engines very interesting.
What i would like to find out is, when a website is submitted to a search engine on some it can take many months before it is included. But then there are companies that can include a website in search engines in a matter of days. How is this possible? I know some charge fees for this rapid inclusion service, but do they twick the coding, i.e keyword tags or use special software?
look forward to your comments

At least one search engine (Gigablast) may sometimes spider and index a page within minutes after submitting.

Simply a question of putting you forward in the queue.

AFAIK they don't.

Different search engines (which are different companies) are like individuals, everyone is different. If you are researching, perhaps typing in "search engine optimization" in your search, you will learn quite a bit.
SEO is the practice of setting up a web page (a page, not a site) where the page is "friendly" (readable) to search engines. BOTS, or crawlers, visit sites, looking for certain, standard information in the HTML code, like the TITLE and DESCRIPTION. It is the crawlers timing, and the importance of the page title, supported by the page content, that helps make the page friendly to search engines, and for the page to rank well. Some crawlers visit quit quickly, others visit on their own schedule.
There are some search engines you can pay for inclusion (PFI), which will visit you very quickly.
There's my two cents. Read more here at WW, and you will be able to not only write a report, but perhaps several books on the subject of search engines!

I have three sites I update daily and whenever I upload a new site I link on these 3 sites.
The quickest I've had a site indexed is 30 minutes and the average is 1 to 3 days.
Because the 3 sites are updated so often google crawls them often.

For me it's worth the effort because every new site I put online for a client gets added same day or very soon after. Giving them a nice big free PR boost also keeps them happy :)
By me having 3 sites I update daily I have a very good chance that google will crawl one well enough to add the site super fast.
I haven't bothered submitting to search engines for a long time now, never need to anymore.
Hope that helps.

I was not aware a site gets spidered more often by Google if it is updated more often.
Do you see any other SE's that work this way?
Thanks again for the tip.

I agree in everything you have written and only have one thing to add. There is one more factor that most likely has a rather large influence on the willingness of search engines to spider a website often: Its "importance" which in Google terms is largely identical with its PageRank. I am fairly sure that I can see that factor in the different spidering patterns on my own websites.
Do you see anything like this?

I haven't seen the PR playing too much into it. My main site wasn't updated a few times a day until recently (6 months ago) when I started blogging and adding more daily wallpapers to the site. It had a PR of only 2 but google was indexing it daily'ish regardless. It's now on PR5 (soon to be 6 hopefully) and I haven't noticed any difference in google crawling the site. It just started crawling often when I started updating often. Google took a few weeks to figure out I had turned a semi-static site into a daily updated site but once it knew that there was no stopping it coming back for more :)
My blog is set is archive each day which generates a bucket load of new pages and I manually update the date on the frontpage each time I update the blog so google knows I've been busy. It still takes time for it to perform a deep crawl (think it only does them once a month) but the frontpage is always being re-cached.
I'm not 100% sure about the next bit but I'll share anyway to see what others have found...
I've been a web designer since '96 and some of my orignal sites are still online to this day. What I've started doing is link exchanging on them and I have noticed that google is caching them more often than before. Again, I update the links every day. It doesn't crawl the pages as often as my desktop wallpaper site but then I'm not updating the main pages, only the links pages.
Google does like activity on a site and it certainly speeds up the process for adding new sites from what I've found.
