Dom,
I love the old look! I do not praise websites often but yours stands out.
I think your old site is stunningly attractive and better than I have had for years (from an image and look feel perspective); I like it a lot. Before I changed it much, I'd be interested more in Jim's research against black. I do think I would keep at least a bit of the black boarder, near the top against the orange which is so stunning. If you decided to put the greys.....Perhaps radiate the lighter graphic grey scales and colors towards the lower side of the page where more content resides. IMO your site is better than the sample grey site that Jim posted but I do not know much.
As far as content......I created a website (with my business kind of background[mind], i am not html or programer type personality). Form 'a me telling you-the customer' who I am and what I do sort of thing. It was a static site, simple, 5 pages almost a template....actually it might have started as a publisher or power point template that I added my photos, colors and text too. I gave that publisher file to my brother who is a Html coder and he built it for me but took a while to get too it.
So in the 6 months that he got around too it, I went and created a wix edit myself, site for dummies but only after reading about 20 Google/website and SEO books from Amazon.com, top published and recognized authorities. I also read everything that Google themselves post on their site about making good google friendly sites. Their mantra is good content, content, content aimed at the customer not Google.bots.
With all this new knowledge, hundreds of hours or reading, blogging on SEOmoz and other site.... I created a 22 page of good content (one page for each of the key terms I target (also embedding semantic linguistic similarities), doing much of what the books recommended for good SEO but all white hat and no gray or black hate stuff. That second site has not ever come close to ranking as well as my old site written without the benefit of all the Google SEO advice, SEO forums advice, books on how to optimize websites advice........ So I got an evaluation from a top California Website SEO guru who makes his living with SEO for restaurants in Los Angeles and I also consulted with a Google SEO guy who worked for Yahoo for a dozen years and I got graphic redesign by the Top art talent for Ebay. All of this advise got me exactly where I am now....not much better than what I had already did myself 2 years ago without any Google specific or seo knowledge. Without spending thousands on gurus and advertising specialists. So I pretty much come to the conclusion that this field is smoke and mirrors- a racket.
So do not contaminate yourself with a bunch of research in this field. Just use basic advertising layup sense. It shoudl look attractive, it should look professional but not over the heads of the people you target. If you target fortune 500 clients it will have that look and feel if you target mom and pop it will have a retail feel (thus my dog logo designed by the ebay advertising rep who worked for the top advertising agency in the USA at the time). Tell your customers who you are and what you can do for them as well as how your business is different from other choices that they have.
Just as in every flyer or mailer advertisement, you always want to tell your customers in a prominent way "who you are" (how you are different from competition; "what you can do for them"; what you want them to do: "Call Now" "Call us for appointment" "Call us for our nearest store" or some call to action. This should be on every landing page. This is what others are getting at above....
Stay away from the SEO vudu and just do things that make sense:
There is meta data for your geo location use it, give a thoughtful description, make your title say what you do | where you do it. If you use photos use photos you have taken rather than clip art. If you wish to see an example of my old (site that still does better) and new 2 year old website look at my sites below. The west store is the original site I did with no knowledge of Google SEO or how to do a website information. I used basic advertising ideas but failed to put the call to action. The rest of the links go to my new site which does not do nearly so well as the old site.
I am no expert, this is just one mans opinion and facts based on my own study of my few cases.
I did also build a site for
http://www.KS-Sprayfoam.com and it ranks multiple times in the first page of it's 7 key terms often first and third. There are not nearly as many spray foam insulation companies as there are computer repair.
