Use Unique Name
I mean,just think about it a little bit,dont let your steam name be Kennys or PaszaBiceps,cause there's a lot of people that call themself like that,you want that unique name,think about it like 5 or 10 minutes.If people want to search you on steam,if you call yourself PaszaBiceps or Kennys it will be impossible to find you!

Unique Steam Profile Picture
There are thousand of people have the Fnatic Logo or another team logo,dont you want that unique avatar that no one have?If you are good on photoshop or photoediting you can make it by yourself,taking inspiration from other images you like maybe,or,if you are not good with these kind of things you can just search for someone on the internet or on steam that can make you one!
These profile picture that someone offer to you,to create for you,are really cheap! Just like 1 euro or less!

Custom URL
It's not very important but i think that those number that make up your url are pretty ugly so go on Modify Profile and put in custom URL your unique name or something else!

Description Of Profile
You want to write something about you or you're profile or you're rules,but you dont want that ugly grey looking letters,add Basic Formatting!
It's pretty easy,you go to write something,in the lower right corner there should be a rectangle with written above: help formatting,just click on it and you will find all that you need,just like highlight textes and many other things.

Use Emoji's
In Your Description on in your information,but I suggest you to put them only there cause i dont like so much them in the name's.
After all you can use them in your description to highlight your rules,like this:

:reaper: Dont bla bla bla :reaper:

doesnt look that so much better? ^^

How I can get a ton of emoji's you will ask?
Well,if you have seen someone that you really like and it's cheap buy them! Or combine cards of game,you will get almost always an emoji of that game.

If you want to go on here you have to spend a little bit,do it only if you have money for it

Cool Background
Search one that you have or just buy another one,it will make your steam profile look better,i reccomend you to dont chose a grey or black blackground.

Put Your Best Badges Or Medal's
Put the medal's that you have hard achieved.Not an ugly level 1 thing.

Gif's
Everyone love gif's,just search for one that you like or edit it by yourself(there's a lot of site on google that can make this for you and all free!)and put them on your showcase.

Image's
Same stuff as gif,search for them or create your personal one,like the unique avatar,contact someone or edit it by yourself!.

Screenshot
Do you have some really nice screenshot?put it in your showcase!People love screenshot,just share to all the people that visit your profile your masterpiece!

Item's
If you have some really good in-game items,put it in your showcase!

Combine All!
If you combine your image's with your background it will look amazing!.There's a lot of site on the internet where you can experiment this!

Theme Your Profile
Make it themed blue maybe or the colour that you like,all blue items or the colour that you like and background.

Reputation
+rep are a fantastic thing to make look better your profile,i dont suggest you to spam it,at your friends or who you thinks that deserve it just leave it :D
Also,if you want to spam it just leave a comment on who's gonna comment down there,if they're nice guys they will reply with a +rep.

Emoticon Moisacs
I love this thing in particular,it's an image of your chosen made with emoji's,an example:


If you search on reddit you can find a lot of this,the creator sometimes will leave you the code of the emoji's to do that really fast,so you have to just buy those emoji's,or if they dont leave the codes you can try to remake it,or just experiment with those two site that i will leave you:

http://a9.io/Steam-Emoticon-Art-Editor/

http://steam.tools/mosaticon/

to put the code of the emoji's when you're done you have to:
go to 'Edit Profile' scroll down to 'Featured Showcase' and pick 'Custom Info Box' ,Then write down the code's, press 'Save Changes' and you're done.

Your Name Written With Emoji's
If you wanna do a thing like mine,on my profile,your name with emoji's you can search for the letter that you want,buy them and in the item showcase put them in order and BOOM you're done.
Also i will leave you a tip,if you buy the game Lyne,his achievement are just letter,that you can put in order to make your name with the achievement showcase,the game is only 2,99 $ ;)
