If you have a website it means you have a host too. If you don't have a host that means you don't have a website. Two major option available for web hosting are shared and dedicated hosting.

Website that uses dedicated hosting has a server for it site. Full server resources to a website besides a shared host is split amongst more customers.

Servers are simply computers that been set to respond to data request from the Internet. Each server has an Internet Protocol address (IP) i.e. 10.10.1.100

Shared Hosting
One server is shared with many websites and resources are also shared with all accounts on that server. All sites sharing same disk space, bandwidth and IP address of that server. Host limit each site to a specified amount of disk space and bandwidth to be used by per user per month and also limit to not to use more server resources. Site that exceed their limit may temporarily closed down for that month.


Dedicated Hosting
With this type of a server, all resources of the server, as well as the IP address, are unique to that website that uses that server and you can use as you want. You can host as many site as you want. All bandwidth is yours, you can use as much disk space you needed for your sites.

Big websites that receives lot of traffic really need a dedicated server. Hosting big website on shared hosting is not good thing. Your will be slow and sometimes your hosting company that giving you shared hosting will also advise you to move your site to a dedicated server. As full resources is yours so you can run any script you want.

On shared accounts you are not allowed to run all type of scripts. They don't allow scripts that use lot of server resources.


The main different between them is their cost. Shared hosting is more cheaper then dedicated server. You can get shared hosting account as low as 1$ per month while dedicated account can cost more them 75$ per month.

There is a very big risk in shared account. As there is more then 1 account in same server if other user run a script that goes bad, the server could be affected. In some conditions your site could down for a while. If your member do somethings wrong with search engines like using proxy and other things. SE bans server IP address so your site on that server that will be also banned from SEs.

How To Choose Between Them
Small companies with small sites are better with shared accounts. The cost is very low. Make sure to choose a host with good reputation who protect your site from other that could put your site at risk.

Large site needs dedicated server. Its also good for developers and researchers who test new technologies.

Web Directories: If you have made site its time to submit it to directory. Do this work slow and in long term because getting lot of backlinks in short time is not good for search engines. They will ast your site as a spam and your site will get chances to get banned from search engines.

1.Free directories: This are free or open directories where you can submit you sites for free.
Some Examples of these type of directries with PageRank-

2. Reciprocal Link Directories.
This is type of directories where you have to link back to directory. Its like link exchange.

Social Bookmarking Sites
For those who are new to it, in social bookmarking system, users store lists of Internet resources, which they find useful. These lists are accessible to the public for their views and comments. This became a great seo technique now

I advised to use Both.

Many Directories ask for a reciprocal link when you submit your site to them. But the end they do not list your site or blog to their directory. They make their own good PageRank on search engine by getting one way link (inbound link) from your sites.

Sometimes its not possible to check all directory that they are linking back to you or not.

Some Tips:
1. Always check each directory you submit your site for link back.
2. Before submiting your site don't forget to check that direcotry is not banned by search engines.
3. Submit your site in proper category.
4. Try to submit on directories that have higher pagerank.

Are you still thinking to cheat AdSense? Stop that.
It will never bring you anywhere. You can do this with smaller ad network but not with Google.
Here are some of the detection methods Google might use to catch cheaters.
At the very least, they have the resources to do so.

IP Address
If the AdSense click is originated from the same IP Address as the one used for accessing your AdSense account, your account is flagged.

Cookies
Most home users do not use static IP Address for Internet connection. In most cases just disconnect and reconnect will give you a new IP Address. But don?t forget, Google has set cookies on your computer.

Other Google Services
Thinking that you are safe just because you do not access your AdSense account? Think again. This time, consider these: GMail, Google Earth, Google Calendar, Google Search, Google Toolbar, Google Talk, Google Sitemap, Google Desktop, Blogger, and so on, and so on. With the wide range of services they provide, Google can trace the originator of most (or probably almost all) clicks.

Click Pattern 1
Oh, why this computer / IP address / person is so trigger-click-happy on this particular website but never click on the ads on other sites?

Click Pattern 2
And why is it that people accessing these sites direct (type-in URL or from bookmark) tend to be very active ad-clickers compared with those referred from search engine or other sites?

Click Pattern 3
And why the ad-clickers like to hit and run, compared with non ad-clickers that surf a few pages before leaving?
Click-Through-Rate (CTR)
Your CTR may range from 0.5% to 10%, but if it exceeds a certain point (probably around 10%), you are flagged.

Geo-Location
Used Urchin (Google Analytics) before? Then you should know that Google can trace traffics origin down to the small town. Different IP doesn?t mean much. Unless you site is really targetted to one small geo-point, a high number of clicks from nearby location will get you banned quickly.

Hardware address?
MAC address of the LAN card, modem, and router works almost like a fingerprint. I?m not sure if Google can track this, but probably they do. They have rocket scientist, remember?

Advertisers conversion rate
Ad click is one thing. But does it bring value to the advertisers? If none of the clicks on your site translate to conversion to the advertiser, you are in trouble. First the Smart-Pricing hits, then your AdSense account disabled.

Search Engine Ranking
Your website is not indexed on any search engine, not linked by any prominent website, but get consistently high traffic? That sounds like something is in play. Regardless of whether it is an adware-embedded software, spam, trojan clickbot, or intentionally installed click-exchange network, it doesn?t sound right.

Webpage design
How about the ?click here? or ?support us?? Google has the best search engine in the world. Is it really that hard to find those words?

Combo
Each of these detection methods might seem rather weak. But combine them together, and not many click-fraud can pass-through these filters. Even the smartest clickbot will have a hard time.
In short, it is impossible to cheat AdSense for a long term. Instead of spending time, money, and effort trying to outsmart Google, try some tips to improve your AdSense earning.
Note : I m not working for Google nor in anyway know anyone inside Google. Google might or might not use these methods to detect click-fraud. I think believe that they have much better detection mechanism.
