Basm allah alrahman alrahim

keywords today is not important ,( i.e the keywords we add without knowledge ) , but what if google change that ? and what about other search engines ? and what about new search engine that will appear ? what will you loss if you write keywords , its just a words ? just write your articles or your website pages then put the most important words as a key words , observe that there are some thing called niches ( it a keywords but not a keywords ? ) and important words that can make your website more effective and with top ranked in google bing yahoo and others

Note niches ( it a keywords but not a keywords ? )

Example

when you write a question at your website in maney ways like :

How to create a website ?

How to design a website ?

How to create a site using wordpress ?

How to make a web pages using joomla ?

How to create a page using drupal ?

you will find that you make many keywords to the same question , and when you put that at your search engine using webmaster tools , any search engine will make your search at the top ranked ? why ?

because you start to think like users thinking (i.e any one want to search for making a website will think to write a question at any search engine from the above choices , the more choices you add the more you will be ranked , of course thats just an idea of what happing and SEO is a lot bigger than that )

I think SEO specialist from the most important specialist
