I have a couple of accounts which have kw history and CTR of between 6 and 8%... I have not used these accounts since 2008/09. Can I benefit from the KW history and CTR on these after so long? One account still has about £70 credit on it (forgot about that) or should I start afresh? This niche is bound to have become a lot more competitive in the last 3 years and is now dominated by some big players. Are there any online tools which can give me a heads up on current click prices for kw phrases? I have 4 years worth of KW data and conversions per website hits so know how to structure my campaigns and how much to chuck at it per day to get meaningful returns. Would Google give me any more credibility (and see me as a serious player) if I loaded my account balance with a few K to start off with rather than dripping a couple hundred every other week? As always cheers for any tips.
