Recently, I pay more attention on competitor analysis, which is considered so important. However, I want know the daily traffic of each competitor’s site. In addition to Alexa and Google Trends, which tools else can get approximately accurate info. Thanks in advance.
Google is probably the best free keyword research tool. You can do most of what you need there, but it's great to use other tools to cross reference and get different perspectives on what you are doing. Market Samurai is a great tool to take keywords that you see from google so that you can get more in-depth information on your keywords. You can get a free trial of market samurai. When you use just one keyword tool, you only get one perspective.
Hey when you are talking about free tool i suggest u try "google+bling" . use the "link:" while doing your research.
