A while then, they started spreading over the network.

Today, viruses are being spread to your website. Now, how do they do that ?

First of all, it's quite simple. The viruses that you pick up downloading files from some suspicies websites are installed on your computer. Then, they search for your ftp details on your computer. Usually, you save your details with your ftp client. They connect to your ftp service, search for index-like files (index.html, index.php, ...) and when found they modify it with their own code at the header or footer of the file. They usually put the code for promoting other websites, or in some case put a link to a file to infect your visitors. Naturally, your visitors trust your website, and they will download the software which will get their computer infected.

The key for your protection in general would be:

-not to keep your password saved in the ftp client (Don't mind typing it every time you connect, as it will save you time in case virus infected you, or somebody hacks your computer)

- keep the backup of your website, so if you get infected, you can easily re-upload your website with clean code

- keep the antivirus updated. Antivirus is a good prevention, as the latest updates usually can reckognize and detect the viruses being downloaded from the web, thus prevent infection of your computer.

These types of attacks are just starting to appear. I have personally seen just a few of them, so it's not that common. If you had an experience with it, and would like to share a method for prevention, please feel free to post a comment.

Often people associate offered bandwidth with network capability. Those are in fact, two different terms.Bandwidth is associated with amount of data you can transfer (both up to your server + and down from your server) in a period of time. Network capability, on the other hand will have a direct impact on the speed of your website and quality of one enjoying your content and online media.Your search engine ranking is also affected by your network uptime and network speed. Your visitors will return if they enjoyed your website's response.

Let us look at number of factors that affect your network capabilities.

Provider is actually routing your traffic !

Network data is like a car in the traffic jam. You will take a shortcut if there's a shortcut available.If not, you just might get late for an appoitment !So, what do providers of your internet service like hosting companies and "last mile" internet providers have to offer ?Larger companies will have an psychical connections to other larger networks. They will invest in optical infrastructure to have their network connected to other larger network, and that's called peering. For example, if you have a website on one network, and your users mostly use large network like telia.com, your provider of service will route the traffic through that particular peer, and users will get response in no time.If your provider doesn't have a connectivity to telia.com, then it will route to another network that has the closes route to the desired destination, and of course, that will cause some delay.Nowadays, network providers do have a lot of "direct routes" to their fellow networks, and that will ultimately affect their quality of service, since the delay between responses will be much lower.Your provider of choice would actually be the provider that has a full redudant network, which basicly means that he has one or more routes towards an another larger network, and will offer 100% of network uptime to your website.
Your server's country can matter ! But then again ...

Your website can target a specific country more then others. So, you would normally guess that hosting your website in your country is the right choice for you. Well, you are right more or less.Having a close peer to an end-user is a good choice, and it will provide a fast response. Issue with local hosting providers is that they can have a good connectivity localy, but the amount of data transfer is somehow always limited. That's due to infrastructure that most countries don't invest in building large networks, simply because there's no primary need for that investment.On the other hand, there are a quite few professional datacenters, even though you are not in US, or maybe not in Europe, that will offer a few milliseconds delay, unnoticable to your end-users, and at the same time offer redudance (having an alternative if one route fails, which most local networks don't have), and capability to have a large amount of data transfered (again bandwidth) at low cost.

Unmetered bandwidth is so cool, but my website is slow ?!

Some providers do offer unmetered bandwdith. They are maybe slightly more expensive, or even cheaper, but in any case that sounds very good.There, of course, is a catch. Look at it as a one way street, with no semaphors, and cars trying to drive into the major highway.You can have there thousends of cars, and they will all enter the highway. Well, eventually ... though.Providers that are offering unmetered bandwidth are basicly giving false information. They are telling you that they will not measure your data. But they are mostly not telling you that you that:- you cannot use media streaming- if your website is using too much, you will get disconnected- you and hunderts of others are all having 10mbitps, but you are all sharing it.
That's basicly the story. And sometimes cheaper is costing more, costing you your website's quality, as it's directly connected with end-users pleasure enjoying all your hard work you did put in your website.

It is a very popular way of hosting the website, as it can be quite cheap and useful for small websites not spending alot of resources.

The main disadvantage of the shared hosting is that you are basily living in the same enviroment as other websites.

That can put a question of theoretical risk for your data security, for your emails going through (You all are sending it from one ip address, if one is spamming, all are considered spammers), resource measurment, etc...

If you would need a special software installed for your application, some hosting companies will install it for you on the shared hosting, but majority will not. The solution can be found in one more profound technology that is fastly growing in popularity.

So, what's VPS ?

VPS stands for Virtual Private Server. It's basicly shared as well, but in terms of resources. On the shared hosting you will share the enviroment, services, etc., but on the VPS you will share the memory and CPU.

You will have "root" access to the machine, and will be able to install and configure your virtual server as you like.

Some of advantages of the VPS are:

- Server performance: All resources are equaily shared. One user cannot overtake the whole server with resources, so you are on the safe side there.

- Private mail server: You don't have to bother with the risk of being blacklisted because of other shared users

- Your distribution of choice: Basicly, there are quite a few hosting providers who allow you to choose between different Operating Systems. So you can continue to work on the distribution that you are used to working at home.

- Security: No one, except you, has access to your VPS server, and that minimizes the risk that your data will be stolen. You are practicly isolated in the enviroment with your own services and resources.

- Custom applications: You can install any application that you would like to be installed on your VPS, as long as it doesn't use more resources then you have.

There are number of advantages over Shared hosting, these mentioned are only a few.

If you are a user who is ex-shared hosting user, I would love to hear your opinion and experience with VPS enviroment.

Google is fastly modifying it's algorithm. It is looking at more and more things to "harvest" the right websites with matched phrases and keywords.

So here we go:

- the name of the page should contain a phrase or topic of the page.

That way search engine will known for certain it's about “that” in page.

(ex. Travelling-around-the-world.html)

- meta titles should always be describing the article to a certain level. Not too much though, should be kept lower then 150 characters

- making a list of tags (common words that are used on the website)

"Tag" the pages and internally link them, so one can get a list of pages containing a certain tag.

It’s also useful to link a word (tag) on the article itself to a tagpage.

Also it’s good to use tags that appear on that page in meta keywords and description as well. It can save time if it’s done automatically.

-       When writing an article, one should use bold, italic, underline, and paragraphs. Search engines pay special attention to these html-tags and they will for sure add a certain point for the ranking for specific keyword of phrase if they found it bolded or such.

Well, these are a few tips that I learned this weekend. If you want to add, correct, or remove some of these tips, please don’t be shy to comment.
