hey friends, this is gana., i want to know best keyword competition tool(i.e., from original competitor site), keyword research tool. and how to assign a back links for each keywords. is it based on search volume or original competitor site?
you can use many of techniques one is use inanchor:"keyword" command to know the competitives using your keyword in their sites as anchor text..
Google Keyword Research tool is the best tool for keyword research if you know how to handle this properly if not than go for Market Samurai.
Everyone says Market Samurai is the best. When you use google keyword tool to find the exact number of searches per month for a keyword dont fall into the trap of thinking the competition meter on that is SEO competition because its not - its Adwords competition.
Market Samurai is crap now, since it doesn't uses Google's keyword data anymore. It was good back in the day, but since it uses Bing's data, it doesn't paint you as clear of a picture when doing keyword research.
you can easily know by typing the perticular keyword name if my keyword is packers movers then type packers movers and total competition for that perticular keyword will come in front of you.
Traffic Travis has a decent tool but if you are using the Google adwords tool, look for keywords that have less than 50,000 results when you Google "keyword".
A great keyword tool to try is Wordtracker - you can take a free trial if you so wish - search for Wordtracker in Google.
