Eve is a very complex game. Thankfully, there's some external websites that help with issues. Below are links you may want to bookmark in your browser.
Some of these require a login through your Eve API key or TEST Service key which will be mentioned above the description.

This is your main source on rumours, scandals and information about what is currently going on in Eve. It is also a platform where propaganda and drama flourish, so don't take everything as 100% true.

You can guess from the name what this site does. It is used to find the current value of one or multiple objects in the main market hubs (Jita, Amarr, Dodixie, Rens, Hek) and the average across the universe. To use it you have to set your inventory to list mode (found in the top right corner, right under the 'x'), select the items you want appraised and copy&paste them into the website's window. The default market hub is Jita - the biggest one by far.
An alternative to Eve-central, this out-of-game market browser with an interface that is nearly identical to the in-game market window. Useful for checking prices across all of New-Eden and the familiar interface makes it easy to use.
Coolbean takes almost all stuff you contract to him and sells it in Jita. In return you get ~90% of the estimated profits. This is often preferable to selling them in Nullsec where you can expect much lower prices (meaning less profits). Coolbean is to my knowledge the biggest buyback service in TEST region, has been long in the business and is reliable, but you may want to ask around for smaller buyback services which offer a few more percent and help small businesses.
– an amazing human-readable map of New Eden with statistics combined with corporation and alliance historic information.
– a character monitoring tool useful for planning skill training. The TEST Skill Checker provides skill plan files in the EveMon format.
– an out-of-game fitting tool. Perhaps less essential with the addition of Simulated Fitting to the game client, pyfa remains an excellent utility for prototyping ship fits without spending ISK.
— an ugly little utility for keeping track of your assets and market orders, their locations, and their market values. Great for managing stuff between multiple characters, watching market orders, and monitoring growth.
– a handy little tool intended to warn of gate camps along travel routes. Always remember that an absence of intel doesn't indicate the absence of a threat.
