Anomaly - pure combat site with a chance of faction spawn/escalation. You need ship scanner or scanner probes to find anomalies. Just kill all of the rats and at the very end you might get faction spawn and/or escalation to some DED site.
Signature - Wormhole, Rad/Mag/Grav/Ladar, DED plexes, unrated plexes. You need scanner probes to find signatures.
Radar - here you find stuff used in invention ( needs codebreaker )
Mag - here you can find salvage ( including T2 ) and T2 rig BPC's ( needs salvager and/or analyzer )
Ladar - gas cloud harvesting
Grav - hidden asteroids for mining ( might sell the location to some miners if in hisec )
DED - rated combat site with final overseer or overseer structure, which drops Deadspace loot ( Corelum, Pithum etc )
Unrated Complexes - combat sites with chance of escalation that can lead to Deadspace loot ( you can also get faction spawns here )

DED1 - DED4 -> hisec
DED4 - DED6 -> lowsec
DED6 - DED10 -> nullsec

In hisec there are some limitations as to which ship hull can use acceleration gates. Some sites allow only frigs, some cruisers etc.

All drops/sigs/faction spawns/escalations are totally random.
You do 10 sites in a row and get nothing out of it ( very likely ) == working as intended
You do 10 sites in a row and each one drops container full of Deadspace loot netting you billions ( not likely ) == working as intended

Minor corrections:

1) You'll almost never be able to sell a grav site location, but who knows, you might get lucky.
2) Combat ladar sites exist and require a codebreaker. They can drop booster BPCs, booster reactions, very tasty skill books, gas harvesters, and implants. They also can spawn named rats with a chance of faction gear (though I've never seen them drop deadspace gear).

Don't forget all the nice comedy items you can get from them. Classics like: "the little pirate that could - Inspirational story if there ever was one. Fills every pirate wannabe with pride", "Navigation for dumies - Gives you the answers to all the important questions such as: Is starboard left or right?" and ofcourse "Pillaging 101:

This informative brochure contains helpful diagrams and elaborate tutorials on how to effectively function as a successful brigand. Key chapters include:

Priority Pillaging GÇô Triage style tactics for post-combat logistics

Pursuing Passersby GÇô Why anonymity is more useful than infamy

Punishing Pirates GÇô What to do with a drunken crewman early in the morning

This handy guide could turn even the noblest capsuleer into a ruthless raider in just a few short years of night courses."

I actually never found a ladar site in high- or lowsec space. I don't explore in 0.0 (unless escalation) and don't live in WHS atm.

Can someone confirm that ladars are absent in high and lowsec?

Lowsec has ladars.

There is a definite lack of resources out there that lay this all out clearly. When I first started doing exploration it took me untold hours to assemble the information laid out here. Maybe there are better guides since then?

I will mention an example: There is a lowsec type of site, that is relatively easy and can escalate. If you get it to go through to the end you can find some of the more expensive modules (barring officer mods some of the most expensive ones in their respective group). Now there is much 'chance' involved in the whole chain and most people will usually just go for the rated complexes, however for someone that is adventurous and has not the best combat prowess it might be a good thing to do these type of complexes. The Information on how to do this site can mostly (not for some factions) be found quite easily, but as it is mostly not so popular, it doesn't attract so much attention.

Also: don`t be afraid to get ships blown up, especially by npcs

Despite all that, you don't know what you are talking about.

Those that Escalate say so.
