The link back to googles API is crap – it keeps coming up with password authentication which renders it virtually useless when trying to find your own rank. Sells you the software initially. But then tries to sell you a load of stuff afterwards which effectively tells you the first version you have already paid for is useless without the extra “bonuses”. Not a nice way of doing business
This database was built using data from BEFORE Google required active ad accounts to get good keyword data & before they started blending data together for similar terms. Even if you set up an AdWords account and spend significant sums of money with them, they may require you to run your ad campaign for 3 or 4 months straight before they will show reasonably precise data instead of exceptionally broad data ranges.
If you already have a keyword list, the Free Keyword Grouper can transform your list (up to 1,000 keywords) into an organized keyword structure ready for high-performance PPC campaigns and an SEO-friendly information architecture. Just paste in your list to get back keyword groups in seconds. This keywords organizer tool will help you sort your list of keywords into structured, workable groups that can then be used for easy ad text creation. The keyword tool can also be used as an SEO keyword organizer to assist in site design.
The limit on manual keywords could be higher. I personally wish we could input 10,000 keywords at a time, instead of 200. However, I understand the costs that Long Tail Pro has to maintain each time a new manual keyword is input. Not a deal breaker, I just wish the limit was higher. (To be fair, I don't think most keyword tools have a bulk manual option at all).
