Hello.
Is it possible to track a public address to know to which wallet or pool does it belong?

An address (or more accurately, it's private key) can be imported or used by any wallet.
Some addresses are publicly tagged and known to belong to some pools. Most of these tags are visible on blockchain.info

The blockchain and all transactions are visible to everyone. You can track everything yourself if you want to.

OK lets say you can track an address which in result you going to find what? another address?
But if you want to find the owner email and stuff I doubt it because not every one using online wallets or better say third party wallets.
Once you run your own wallet then I guess you could only find the IPs used with those addresses.

I also would like to know more from an expert.

The first thing that you could consider is whether the address that you want to track is a vanity address. Vanity addresses often contain some string that is somehow related to the user, which could come helpful in looking up what wallets and pools the user is participated in.

At all BTC addresses, as @unholycactus wrote above, all BTC transaction are publicly visible on the blockchain so it is possible to do some research with them and base a guess on the results of the research. Actually, you do not have to do this research yourself because there are services that are doing it already. You can continue with the checking results part. WalletExplorer (https://www.walletexplorer.com/) may help you.

Blocktrail  (https://www.blocktrail.com/)is service that provides information about an address from mentions on the web. It could come useful in addition.

A wallet or a pool may be hard or impossible to track, the most you can get is an address belonging to a service, let's say an exchange, a sport book etc, those services may have a cold wallet address known by many.

Not sure what OP's goal is, but beyond WalletExplorer there's also BlockSeer (https://www.blockseer.com/)

The problem with these it's that they don't link every single address to a wallet, it only searches the blockchain for spend-linked addresses. Nor does it show ones in the mempool.

Linking addresses to the same wallet is something hard to do as normally one doesn't have information to be 100% sure that a set of apparently related addresses all belong to the same wallet (or owner). I don't think there's a tool like these that shows transactions in the mempool related to the address you're searching.

But all the transactions via that bitcoin addresses are in public ledger only right! We can see that through blockchain.info. If we just Google the bitcoin address we can find the relevant result in Google itself I think.

No, it doesn't work like that. All of the addresses in a wallet may not be necessarily linked. In fact, it can be fairly difficult to determine which addresses belong in the same wallet. Furthermore, people don't just post all of their wallet addresses publicly. Googling it isn't going to help.
