I am looking for any website where I can see a list of most popular keywords, which contain at lease 8,000 keywords.
Google Adwords is a great place to join, you can check it out, Keywords are the most important SEO element for every search engine, they are what search strings are matched against. Choosing the right keywords to optimize for is thus the first and most crucial step to a successful SEO campaign.
I know, Adwords is the best tool for check any keyword. But I am looking for a list of most popular keywords for the beginners.
You can use Google Adwords as other members have suggested. I also use Google Insights and Ubersuggest. Hope that helps. Have a good day!
Google Adword tool is best, no doubt. But this tool only help to put any keyword for popularity check. But the people who still have not any keyword, where they can found a list of keywords?
The use of keywords depends largely on what your site is offering, a blog site would need to have keywords relating to the posts within the site. A site runnning a blog for cup cakes would need keywords relating to this, ie. cupcake, birthday, cakes etc. whereas site which is selling products would need keywords relating to those products. Thnnk about how people would search for somethng related to your site then use a keyword tool to provide alternative popular keywords and then incorporate them into the text. To use a list of common keywords for a site would possibly result in minimum cohesion throughout the site (having random blogs with no link to ech other) you may get more traffic but the bounce rate might be high.
I don't see the purpose of getting the 8000 most popular keywords, unless you try to get hold of domain names containing those. But I can assure you that it's very unlikely you will be able to get hold of a popular keyword domain and, even if you are lucky, you will find out that the competition is fierce and having just the domain name will do you no good. As Emma suggests, try it the other way round: If you have already a website, look for keywords that "fit" that website and exploit those. Adwords, as suggested by several members, is a good place to start to get those keywords.
