What is a good alternative to Alexa.com for keyword, competitor and traffic analysis?
We want a tool that is comparable to Alexa.com but not as expensive (we would need the highest version to get what we need) to help us with our clients' research in the area of competition online, keywords, SEO audit etc.
You can't go wrong with the Google keyword planner. It used to be accessible to everyone but you need to be signed up to Adwords now (although you don't need to pay or enter your payment details). This gives you everything you need in terms of research. You can then use Woorank for an SEO audit.
