My advice is find the higher converting less competitive terms. Individuals that are search for "Denver Highlands Neighborhood Homes for Sale" are further along in their buying decision than "Denver Homes for Sale". The shorter phrases are more often window shopping. The more detailed the phrase, the more likely they will enter the store and make a purchase. Plus, if you do it right, it is much harder to get knocked knock out by a competitor when you are the first to capitalize on a unique search. If you find some gold in "Denver Lofts for Sale" then try dominating that term.

Large rivers are made up from very small streams.

You should certainly fix this. You don't want google having to guess what you are trying to tell them. For the most part they will probably get it right, especially in your case with the 404s. But if this is occurring too frequently then they may begin to ignore your canonicals all together. Or worse, you may loose some google trust.

I'd put this on my fix it list.

I've found that the SEO community here is very giving. Rand in particular has answered several of my emails and requests personally. It appears that he will be helping you out, so I don't think I can much here.  It's amazing what simply reaching out and asking for help will do for you.

It also appears that this page, which is now public, does not link to your site. So hopefully with permission of  Rand and the community, here is a little contribution to your cause: Down syndrome families

Hope that helps. Looking forward to seeing your cause move forward.

First off, social media for pest control companies isn't nearly as sexy as social media for a taco stand. So any ideas of glitter and glamor are going to be as helpful as a rainbow colored unicorn. Just wanted to get that off my chest before diving in here.

How I see social media as a pest control guy:

1- Maintaining conversations about interesting pest control subjects.

2- Building relationships with current customers.

3- Building relationships with current employees.

On Facebook after establishing a fan base you can use paid advertising to friends of fans, using fans as endorsements. But don't expect huge returns here. It's more building awareness and trust. You will most likely not see Facebook as a last touch for sales. And it's hard to track the first touch.

Funny videos can build links, but I wouldn't consider them great for building trust. I prefer the class nerd image over the class clown image. Nerds are allowed to make jokes, but your know for being smart, not for being funny.

Lastly, check out http://www.familyownedpestcontrol.org we have just launched this lead sharing network, no cost to you.

And if you want to guest post on blogpestcontrol.com I could probably get you in.

I hate to bust your bubble on this, but I don't think you will find such a list, especially with the added criteria of white hat. It's really difficult to fully understand a website's entire optimization and strategy from an outside view. Plus, are we speaking of strictly site structure or all aspects of SEO? Wikipedia kills the SEO game by being so massive and having so many inbound links. Tough one to list off.

But if I had to suggest 5 sites to start with I believe that these sites would be great to study:

Zappos.com - Good site. They do a lot of SEO work on their website. I trust their team.

Logitech.com - A well built site. They try to follow all the white label stuff as well.

SEOmoz.org- Maybe it's a bit of a cop out, but the reason you are here is because they are recognized as an authority on the subject.

http://www.mattcutts.com/ < With the exception that you will want to navigate to his blog. But other than that, his site should follow all the white guidelines.

And per Avinash, http://lds.org does good SEO work. I've also run into them at a SEO conference or two.

Of course, all the above are well trafficked sites and very large. Matt's is probably the smallest of the group. If you are looking for smaller websites then I'd just refer to the search engine and who ranks well for any given term.

I agree. Lowercase in the example above. For ease of direct typing.

But when advertising just a website URL in print offline, caps. www.BulwarkPestControl.com is easier to read than www.bulwarkpestcontrol.com.

I've got a separate blog site. There are benefits to both scenarios. The reason I have chosen to keep them separate is so that I can post content from other bloggers and contributors and not worry about the content being officially endorsed by Bulwark.

If you do move it over to your main site, you can easily export the wordpress site and all it's content to a sub-folder and then do a 301 redirect rule from your old blog. It is probably ideal to have them all on one site so long as the company wants to take claim for all the content written there.
