Well - to start with - I will ignore the SEO part of this, and instead tackle the Expert part from the title.
Okay... now to examine the post contents with more finesse...
- - - - - - - - - - - - - - - - - - - - - - - -
Our own website is listed highly in all the major search engines, this is testament to our own optimisation skills and I believe the only way an SEO company can prove their worth. The excuses I constantly hear of "I don't have time" these comments are simply lies as the same people then manage to post 500 times a day in a forum.
Okay then... "... simply lies ..." - can you back this up? You have Hourly records for numerous individuals in that field, profession or providing that service, that clearly indicates they sit around doing naff all for a large part of the day, or spend a large amount of time doing things that are not necessary and instead could be spent on improving their own sites ranking?
I doubt it (though I would indeed be impressed

)
So - No hard statements nor factuals that are not verified or verifiable please.
Apart from the last part, I like the idea, and I am inclined to agree - you can only prove your worth by ... well, proving it!

We are good at SEO but we are not experts, an expert in any field should be suitable trained and qualified. In regards to SEO, search engines have strict secrerecy clauses are a totally fluid mechanisms. As far as I can see people are only proclaiming themselves to be experts in this area because it is a good marketing tool. The fact very few offer clients long term guarantees, shows the self proclaiming of the title is wrong.
Okay... now for this bit...
Expert
1) A person with special knowledge or ability who performs skilfully.
2) Having or showing knowledge and skill and aptitude.
Adept, Good, Practiced, Proficient, Skilled, Skillful.
Strangely enough - no where does it mention "qualified", nor "trained".
As for "guarantee" - considering the majority of highly respected, renowned, known, publicised and dare I say "experts" in the field/profession/service state that any company offering "guarantees" are to be considered as a little circumspect...
You have o control over how the algorythms work.
I doubt if you have access to any of the specs.
It is unlikely that you have any control over the content of their competitors sites.
Considering those three things alone, I would like to know how you can "guarantee" anything, as the current system is non-static and changeable within a day.
Here's a Fact - with no real effort at all, one of my clients appears within the first page of google - and has done since I got them. I've done no real SEO, I've done no submittals, PR work etc.
They will range from being 3rd through to 7th... and quite often switch places with their most heated competitor.
Yet I make no gaurentees, nor claims to be anything but a web-designer.

The term SEO expert should be only bestowed on a person who works for a search engine organisation. I understand there are some clever people who provide cracking SEO services, but experts, hell no.
Well... I can see the view point... if you are not in the field/profession... surely you wouldn't be an expert.
So, here are two things to consider;
1) I went years without belonging to a MA club, nor any official body/organisation - did I stop beig a MA?
Hell No... I still practiced every so often, and I still proved myself on the odd occassion (I have a knack for the wrong time, wrong place, wrong thing to say to the wrong person

)
2) So, if a person doesn't work for a company that sells shoes, they cannot be a shoe salesmen. Makes perfect sense... yet for some reason, I cannot see that actually stopping them from knowing what shoes are, knowing the price, knowing that someone wants a pair, stops them from getting that pair or stops them from handing the pair over in return for money.
That would mean they sold shoes.
Not exactly a shoes salemens (or woman, person, alien etc. so as not to cause offence

), but it should highlight the minor flaw in the statement.
Seldomly is there anything that is of limited potential or singular application. It doesn't matter what it is nor what it is intended for, it can often be used in other manners/means/ways to achieve something else entirely.
So, I'm not quite sure that stating if you don't for for a company/busiess/organisation that does NNN, you are not an NNN person is true.
- - - - - - - - - - - - - - - - - -
This can also be said of many online businesses, who really is bestowing the title of expert on people? Maybe the honour is found in christmas crackers. One thing is for sure, the term expert is that widley used the employees of McDonalds and Burger king are spending 2 weeks reading up handing in their notice and proclaiming to the world I AM AN EXPERT, HIRE ME.
Now, this I can appreciate (though really, two weeks... it takes them at least 2 Months to become a web designer)

(okay - I'm sorry - just couldn't resist that one

)
So, people are making claims that they are fantastic, experts, especially good at something.... you know they are not, right?
You have quantifiable and qualifiable evidence that even a minor group of those folks have o iota of skill, knowldge, insight or talent in that field?
Didn't think so.

- - - - - - - - - - - - - - - - - -
So - ignoring the previous dissection and shredding.
I actually agree with what I would terma as the principal theme and nadir of the statement.
There are those in this "area" of owrk (that being the internet in general), that make claim to being something - with no apparent justification or proof of such.
I think that it is in fact almost criminal - for almsot all other professions, you need to be registered, to hae proof of certain skills etc.
You cannot be a plumber or electrician without having gained certification.
You cannot be a mechanic without it either now a days.
Yet, in this field, there are those that are taking money from people whilst providing them with what could only be viewed as shoddy goods.
Now... the real blittzer here is along the lines of what ... Ron Carnell ... was getting too...
Who gets to decide what is shoddy.
A Year ago, Iwas producing sites that were good - they looked good, worked well, clients were happy.
They where in XHTML Strict, used CSS and no tables.
They loaded fast.
Most important of all, I looked at over 20 competiros within 25 Miles... and I'd say I was better than all of them.
My sites were shoddy - they lacked some basic Usability features, they did not work well at high resolutions (1200+), and they were not really that accessible (they met the base line only

).
Now, I can say with authority, that they were shoddy - I built them, I know exactly how they work, why they work etc... plus I know I can produce better.
But - who gets to draw the line?
Who is there to state that X is good whilst Y is bad?
What defines something being a good service an naff one?
Well, for a start - clients.
If the client is happy - brilliant.
Not the full measure - as qite often if they don't know, they don't care - they don't realise it's a pile of something nasty, and think it smells like roses.
So, the blatantly ovious answers is certificiation.
(Note - as a qualification, not as in "that one's is a nut and should be medicated).
Problem is... (and I really do apologise for this), all I have seen for qualifications in Web stuff is pure B**************.
Learn to use Frontpage/Dreamweaver/PageMill etc.
Nothig about learning standards, how to validate, Browser compatibility, Usability/Accessability. Nor do they cover trends, design types, client base comparisons, colour schemes, color reactions, image recation, customer retention, attention spans, line lengths, visual appeal, white space allocation, page real-estate... or all the other bits I haven't mentioned.
no - simply learn to use X to do Y.
Additionally, as is often the case with IT, and applies to SEO... it is out of date too soon.
By the time you get your name on the list, it may have changed.
By the time you are actually doing the course, it may have changed.
By the time you have finished... something should have changed.
Okay - it means you have a grasp of the system, you now how tings kind of work, and you should be able to spot trends and figure what goes where with a few attempts.
So what the hell is different from learning to do that yourself, in your own time?
I piece of paper and a shed load of money!
Something does need to be done!
There should be a governing body - an organisation that people refer too, that aids and supports, that verifies work and that people can refer too or pass comment to regarding certain jobs/sites/performances.
Only thing is... are you gonna pay the £NNN per year to belong to it?
Are you gonna handle it well when they say "you suck at XY, but excell at Z12345, so you can only charge X for Y"?
Are you gonna tell your clients that you cannot do part B of the job you are not qualified? Even though you know you can do it, as you don't hae the bit of paper with the date stamp on, you are ot allowed to do it!
Look at the "experts" in our field/s.
They are there as thy have proven themselves, time and again.
People ahve examined their works, seen the results, accepted that their methods achieve the desired results.
They are acknowledged by their peers.
That is "expert" - that is when you rise above the rest and get the creditation.
only others canstate yu are an expert.
oly those that know can make that statement with any veracity.
The only way to solve the issue is to educate the masses.
It is to inform them, give theme the detaisl they need to create their own opinions.
Telling them something is not right.
Claiming that Joe Bloggs blows chunks because 123 is wrong.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - -
So - please, read through all of this... I'd suggest 3 times as I did get a bit carried away.
You will, I hope, see the woods for the trees.
I agree whole heartedly with the sentiment - not the statement though.
I think it was worded poorly.
That aside, I support the idea as I see it, and salute you for saying it.
*cough*
Sorry folks... I think I may have overdone the caffine whist starting that... and kind of got all caught up
