Spurs made a rash of summer signings last year after Gareth Bale left for Real Madrid, but they failed to improve their position in the Premier League table, slipping one spot from fifth to sixth.
The Reds have spent around £80million on six players in the past few months following the departure of Luis Suarez to Barcelona for a reported fee of £75m.
But Rodgers, speaking ahead of Liverpool's Champions Cup game against Manchester City, which is being screened live on Sky Sports 1 in the early hours of Thursday morning, says there is no point in making comparisons between their recruitment policy and that of Tottenham.
Rodgers told Sky Sports News: "It's a different club and different vision we have here. At Liverpool there's a strategy behind what we are doing.
"We talked a lot with our recruitment team last season, knowing that through the summer we needed to improve the depth of our squad.
"Clearly we were not strong enough last season in terms of numbers and quality.
"We always planned to bring in a number of players, hoping we were going to be in the Champions League, so it would give us the opportunity to challenge on all fronts.
"The new players know their roles and we hope they can develop in the future as well. So far, the integration has been smooth."
Among those to arrive at Anfield during pre-season are Dejan Lovren, Adam Lallana and Rickie Lambert, while Divock Origi has been loaned back to Lille after being bought by Liverpool on Tuesday.
