I think it is okay to lie about your net worth and income.  It isn't a marriage bureau, so put it up in 6 digits -- unless you really are a millionaire.   They aren't going to get your estate.  They just want someone capable of being generous.  But we aren't spendy in that way.  So it doesn't matter too much if you boost it a little.

You should probably say what you are looking for.  If you want a sugar relationship, that's what they most want out there ... a guaranteed monthly income.   I don't do that and I don't lie about it, so I just tell them that I'm in it mostly for the sex.  But without promising to be available weekly or whatever.

The sugar bowl is different from the pro world and you have to decide what you want from it.
There are pros, semi-pros,, college toe-dippers and those looking for various kinds of relationships (not to mention scammers).
It is probably more akin to dating than mongering. The girls don't have to accept you, they may like you for your demeanor, your looks or just your money. So figure out why you're in this.. it takes a lot more effort and it's not as simple as booking a pro, so it's more suitable if you want a consistent sugar partner.  
Most gals will want to see your income and worth, either because they want to be sure you can pay (there are a few who just want fun) and to feel they're not dating a loser or cheapskate.

As noted above, there are many reasons for a woman to join Seeking, from a desperate need for cash to a genuine appreciation of older guys/tired of 20-ish douchebags in bars, to wanting to tag along with the rich and powerful, and of course, scammers looking to fleece simps from their money.  

 
You won't be able to appeal to all of them (except the scammers, of course). So consider who you really want to meet (and fuck), and whether you want to find one (or a select few) SB(s) for an ongoing dating relationship, or just rack up a long list of "hit it and quit it" hotties.  

 
Now consider how your ideal POT SB (Potential Sugar Baby) will perceive you. Then write your profile to attract your ideal POT.  As for specific answers:  

 
1. Income/net worth: Make it big enough to show you have the funds to play in the Sugar Bowl, but small enough to set reasonable expectations of the allowance and "sugar spend" you are comfortable with. Ex: if you claim you make $2m/year and your net worth is $100m and you are offering dinners at Denny's and a $200 per date allowance, you will have zero credibility. I won't repost my analysis from 2019, but in general, if you don't have at least $1,000-$1,500 a month in disposable cash (varies by market size and local cost of living), you just can't afford to be a SD.  And as mentioned, income = available cash to a POT. Net worth could be all property, or some other long-term assets.  

 
2. In your "about me" and "seeking" sections, be generally informative about you, your likes, and what you like to do.  Three to 5 sentences in each section is about right. Important tips:  
- Stay away from a "don't" or "no" list (No time wasters, no online, don't be boring, don't be fat, etc.) These will only project you are a hateful dick.  Yes, you need to filter out more POT's but going negative will also prevent good POT's from connecting
- DO NOT MENTION SEX, DO NOT ALLUDE TO SEX, DO NOT SAY OR IMPLY YOU WILL PAY FOR SEX, JUST STAY AWAY FROM SEX IN YOUR PROFILE.  Save that for offline messaging - like texts or message apps. And even offline, keep it vague ("I'm happy to help you out with some bills and other expenses...").  Your screen shots can be sent to SA if a POT decides you have been a dick.  Once SHE has started explicit messages, you can reply in kind. But what works best for me is to guide that discussion to a face-to-face meet and greet (M&G). Now others here will tell you they negotiate all the through specific sex acts by text along with specific allowance before agreeing to meet. This allows them a higher confidence that when they actually meet, they will enjoy BCD (behind closed doors) time immediately.  Try for yourself and see what works for you.  

 
3. Your heading should be catchy, not douchey. "I have the BIGGEST...wallet" is a no. "Accepting 304 applications" - no. "Love to fly" or "World traveler needs a co-pilot" or "Come explore the good life" can all work, as long as your profile fits.  

 
Finally, stay grounded that this is a DATING process, not a hooker booking process.  You want to attract women who want to date you - albeit in a structured, mutually beneficial manner. Don't use hooker terms, acronyms or frame your dates/allowances in "$$ per Hour." It's lets have a fun date doing xxxxx. And I'm happy to help you with tuition/bills/rent/buy some new clothes/etc. when I see you.  

 
Life is good

As usual, Herb's advice above is spot on. Read it twice.

It really does help your focus if you know what you want in an arrangement.  I prefer an ongoing, long term arrangement.  Once I've invested the considerable time and energy to get BCD with someone I'd like to see her again and again, assuming our first encounter was goo.  But I get it that some guys want to hit it once and move on to the next.

Even so, what they want can vary considerably.  For example, I now have 3 SBs I see on the regular. SB-A is a buxom 25yo, single mom, loves sex and likes certain non vanilla activities that I love too!  We've been dating for a year and a half and done many other fun activities besides sex.  SB-B is a slim 25yo, also very enthusiastic about sex, also dating for a year and a half.  But with her I've developed a serious emotional connection, and life-mentoring, cuz that's what she wants.  And SD-C is a tall stunning 30yo who is a tiger in bed, and is really only interested in 2 things: getting laid and getting paid.  She has declined my repeated offers of going out to eat, mentoring, other activities, so I've quit asking.  And that's ok with me!  So you'll probably discover that each arrangement has its own quality.
