I was wondering if anyone has any equations that they use for SEO. Or perhaps just a basic outline of Work + Time + Programs= $$ I'm totally just making this up but how about something like: T = Time (time in hours working on SEO) P = Programs/Software (# of programs used) Pt = Program Time (time in hours program has been running) Pe = Program Efficiency (the sum of all the programs used in terms of efficiency. a different variable for each program used. 1=lowest, 2=highest) Kc = Keyword Competition (0=very competitive, 1=no competition) M = Money ($ x.xx per day) An example of what the equation might look like: Kc (T * P ( Pe * Pt )) * 0.002 = M Here's an example. T = 30 hours P = 3 programs Pt = different for each program Pe = different for each program Kc = 0.5 Example of 3 programs used: Scrapebox => Pe = 1.8 run for 35 hours BMD => Pe = 1.7 run for 15 hours AMR => Pe = 1.4 run for 12 hours SO: 0.5 (30 * 3 ((1.8*35)+(1.7*15)+(1.4*12)) * 0.002 = M M = $9.50 per day I think the equation would need to be written by someone with a lot more experience and understanding then me. But i just thought that this would be a cool idea where you could figure out how much work it would take before you even began

that's hilarious, this is just waaaayyyy oversimplifying, unfortunately there's no formula for that because sometimes Work + Time + Programs= $00000.00 and the true variables are NOT in the number of programs, their efficiency or the hours they are running. I do use formulas to make rough estimates for earnings though, but it's more like: T=traffic (monthly exact) C=cpc P=position on page 1 (as a percentage of likely traffic) M=max monthly earnings potential (T*P)*(C*.4)*.1=M

Cool idea but you would need a load of data to do it plus a lot of time number crunching. I find the biggest variable with clients is the amount of time spent on the phone to them managing them and keeping them happy. Nothing you can really control and therefore you just have to average this extra time out. I have set packages which are priced on time, programs and fudge factor. When doing the proposal, i look at the competition and work out what package will get them the results. What i with client is have

i definitely did not mean Work + Time + Programs= $$ that was just an outline, or example of what i was thinking. And i did suggest Program Efficiency and Program Time, Pe and Pt. It's just that i see all of these people promising that "if you follow these 12 steps, i guarantee ....". And i was just thinking that there has to be some way to "ballpark" what type of results you will achieve based on Time, Programs, Competition, etc. I wouldn't know how to do it, but i know that there are some people who have hundreds of websites targeting different keywords. They would have a better understanding of the work to profit variables. With your equation would an example be: T = 30,000 C = $0.50 P = 1/8 30,000 * 0.125 * 0.50 * 0.4 = M So your maximum monthly earnings would be $750

P is a list based on average traffic per position (it's a rough estimate, influenced by things like how attractive your description is in the SERPs): Overall Percent of Clicks: 36.4% 12.5% 9.5% 7.9% 6.1% 4.1% 3.8% 3.5% 3.0% 2.2% so, if traffic = 1,000 and cpc = $1 (T*P)*(C*.4)*.1=M (1,000 * 0.36) * (1.00*0.4) *.1= $14.40 so if you rank #1 for this kw, $144 would be the maximum you would be likely to make, from just that kw per month *this doesn't take into account similar long-tails you will rank for, it's only per kw, to get an overview of value for a site, you will need to add up the potentials for the major kws T = 30,000 C = $0.50 P = 1/8 in your example: (30,000*0.035) * (0.5*0.4) *.1 = $7 potential monthly income for being #8 for your kw

(1,000 * 0.36) * (1.00*0.4) = $144 is what you'd make if you made 40 cents per visitor in that scenario, a 40% ctr is pretty unrealistic. Insane even. The only realistic SEO equation is site + backlinks = $?.??

a 40% ctr isn't part of the equation - a 36% CTR is average for being #1 for any given KW (link to the study - I didn't make these numbers up http://searchenginewatch.com/article/2049695/Top-Google-Result-Gets-36.4-of-Clicks-Study) you make about $0.40 per visitor when the CTR is $1, it actually could be higher or lower, but I find that number to be realistic if your website is on topic for the KW. that's actually an extremely UNREALISTIC equation - neither the site nor the number of backlinks tell you ANYTHING about the earnings potential.

@thejake: ok, thanks to your comment, I figured out that I copied my own equation wrong here, OOPS! - I have corrected it now in all of my posts so as to avoid newbie confusion. the 36% is CTR from search results, and I hadn't put the ad CTR into the equation. So.... T=traffic (monthly exact) C=cpc P=position on page 1 (as a percentage of likely traffic) M=max monthly earnings potential R = advertisement CTR (T*P)*(C*.4)*R=M to clarify: I use this equation to compare the relative potential value of different kw I am considering targeting. This allows you to realistically compare a high value with low traffic kw to a high traffic low value kw. - I HAVE found this equation to be pretty accurate in practice, it really does estimate pretty well what you are likely to earn for any given kw. ROTFL - now THAT's an awesome equation!
