Hi I'm about to launch a site which consists of several million products, some of which I stock, others which are populated through affiliate deals. Ideally, I'd like to bid on around 25% of these products (the low magin values on the others makes them unviable), however I don't know the limit on keyword numbers in Adwords. Is it possible to have 1m+?
25 campaigns per account. 2000 groups per campaign. 2000 keywords per group. That's a possibility of 100 million keywords in 50,000 groups in one account. Your problem is the millions of products (really? !!!). However, you can ask Google to increase the number of campaigns. You can also open other accounts. But start with one and carefully plan your structure. Otherwise, management is going to be a nightmare. The problem is not the number of keywords, it will be the number of groups.
Yes, and you have to get permission to build a one million keyword account. What a mess this will be for tracking - you'll need tracking scripts from multiple accounts on one thankyou page.
