SEO Experts can do SEO mistakes too. Beware of it.

Some SEO experts do mistakes knowingly or unknowingly in several times while doing SEO for websites. I will point out few common SEO mistakes today. These mistakes can affect negatively in the listing of the website in major search engines like Google.com, Yahoo.com & Bing.com; it is very important to use keyword in search engine optimization. But one must avoid excessive use of keywords. There is a misconception that if keyword is used many times it will result in better page rank. It is advisable to keep in mind that search engines do not blindly follow the keywords. They have set algorithm to track the genuine contents. There is a possibility of getting penalized with excessive keywords use. If you want to get better rank in search engines, always use fresh content with appropriate use of keywords. There is a misconception among people that if page is indexed in search engines, its page rank will automatically get increased by search engines. But that is not true actually. The main thing is that there are some very basic optimization techniques which can help increasing page rank. But unless you optimized properly, you will never get the desired results in Search Engines. There is no short cut to success. Always avoid unethical promoters who promise you to get fast and useful links in blink of your eyes. You may encounter sudden rise in page rank due to massive irrelevant inbound links but these unethical links could result in penalizing your site or permanently banning it from search engines. So, beware of it before choosing any SEO expert for your website.

VoIP

To understand how and why VoIP is necessary, you must first understand how the Internet file transfer. In simple terms what the VoIP service does is to convert an analogue audio signal into a digital audio signal that can be transferred over the internet. In order for a file to be transferred over the internet from one computer to another, the signal has to be cut down into small pieces, called 'packets'. This can only be done if the information being cut up is in binary format, i.e. in the form of a stream of 1s and 0, such as 11000010. very basically, such a stream of binary digits can be cut into small packets such as 1100 and 0010 , sent over the internet, then put back into order when received to read 11000010. As I said, this is a simple example, purely to give a rough idea of how a VoIP phone service sends the data throughout the internet. In practice the VoIP data streams are very much larger as are the packets.

Since the VoIP information has to be in binary form, the signal, of course, has to be a digital one. The digital signal is 'packetized' then the packets sent over the internet. The way this is done is to send the signals from one computer to another until it reaches the destination computer, rather like cell phone signals are sent from one antenna to another till they reach the one nearest to you, then from there to your mobile phone receiver.

In fact the packets will take the quickest route through the internet which can sometimes cause problems in that they may arrive at the receiving end in a different order to that in which they were sent. Some may even be lost, or 'dropped', leading to a less than perfect signal. The VoIP receiver must therefore be equipped with the means to put them back in the right order and compensate for 'dropped' packets.

The digital information is then converted back to an analogue signal so that it can be detected by the human ear. Normal digital phones can work this way, but the VoIP service uses the internet rather than conventional telephone system.

It is easy to see the potential benefits of this type of telephone system. It should be completely free of charge, other than the cost of the internet connection, since there are no wires or dedicated transmission and reception equipment required. The voice signals are sent as easily as you would send email. In fact VoIP services can completely change the way in which we make phone calls
