Issues that are possible to fix

Co-spending
Unless it's a CoinJoin transaction it's safe to assume that all input addresses belong to one person
How to improve?
Try not to send a BTC amount higher than you hold on one of your addresses. If you value your privacy on Bitcoin more than the transaction costs, then opt to send more transactions. Your addresses will not be linked to each other.
Round value
If one of the outputs has a round value (like exactly 1 BTC) — this output can be considered as the recipient
How to improve?
Next time don't send round values: instead of sending 0.1 BTC, send for example 0.10124.
Recipient by bigger value
If the recipient is the smaller output, there's no point in having some of the inputs
How to improve?
Try not to send a BTC amount higher than you hold on one of your addresses. If you value your privacy on Bitcoin more than the transaction costs, then opt to send more transactions. Your addresses will not be linked to each other.

Software-dependent issues that are not fixable

Same address in inputs
There's multiple occurences of the same address in inputs
P2SH multisig types
If all inputs are [m] of [n] multisig P2SH, and all outputs are multisig P2SH, but exactly one of the outputs has another [m] of [n] structure — this output can be considered as the recipient
We use 100+ indicators to measure the privacy scores of Bitcoin transactions.

In some cases the score may be improved, while some indicators are dependent on the software used to interact with the Bitcoin blockchain. Such privacy issues are not possible to fix unless the user changes the app or website used.
Critical - The identified issues are significantly endangering the privacy of the parties involved. Usually, the critical score is shown when it is possible to group the addresses that belong to the same owner or when the transaction has a lot of privacy issues.

Low - The identified issues are severely jeopardizing the privacy of the parties involved. Usually the Low score is assigned to the transactions with a lot of privacy issues.

Moderate - The identified issues are not that severe but can still be used by tracking tools to trace your transactions.

High - The identified issues are negligible and do not pose a serious threat to the privacy of involved parties/addresses.

Healthy - The transaction has no privacy issues. Third parties can’t extract any privacy-related information about the transaction or addresses involved.

General guidelines for sending BTC transactions

Blockchair can not help you improve the privacy of your
transactions but here are some basic recommendations
on how to stay anonymous on the Bitcoin network
Don't send round numbers

Don't send round amounts. Instead of sending 0.1 BTC, send 0.10125

Use Bitcoin Mixers

Mixers add an additional layer of privacy to a transaction to avoid exposing user identities.

Avoid reusing wallets

Don't send your Bitcoin change to the same address you use for sending bitcoins.

Avoid including many of your addresses in one transaction

Any time you can, try not to send BTC from your various Bitcoin addresses.

Avoid using "send everything" option

If you are withdrawing funds from an exchange, it is okay.
If you're moving funds to another wallet, do not transfer the whole amount to another address. It greatly compromises your privacy.

The detailed list of indicators and recommendations are available in API docs
