I don't know whether they're correct, but Alexa is very commonly used to estimate site metrics and it suggests that
Coinbase,
blockchain.info and
LocalBitcoins have all risen significantly in recent months.
It's understandable that Kraken's rank has fallen slightly, because recently Kraken has been known for being a very slow and buggy site which is becoming increasingly inconvenient for traders.
It's kind of a shame that these exchange sites have a higher rank than places for discussion (for example, Bitcointalk's rank is around 1500 while CoinMarketCap's rank is about 250). It suggests that the majority of BTC users are primarily in it for speculative and investment purposes.
