Most SEO people agree that having a single dash or hyphen (-) in a domain name is not a bad thing. Technically, the search engines still see the keywords in the URL and ignore the hyphens.
In the past, spammers have over-used hyphens to try and direct unsuspecting users to their own websites. Having two to three hyphens in a domain name is what has given hyphenated domains such a bad reputation.
Several articles point to the fact that hyphenated domains still appear in Google’s results (and many of these websites are high quality), and are therefore not being penalized for having hyphens.
Using hyphens is not good for branding a specific product or service, but a keyword rich domain name with a dash will still rank highly.

Hyphenated Domain Names: Use Or Avoid?

A good way of getting more keywords on a website is to put together a glossary of terms. This has two main advantages.
First, by putting in a list of definitions, you make the website more of a content site, and one that will be seen for information. It is a great service to your customers and prospects as well.
A great example of this is Grand Entrances . I helped set up this glossary of terms about doors (and learned a lot while doing it). Now, when customers come to the website, they can better understand what the descriptions are referring to.
Secondly, a glossary allows you to pinpoint the keywords that you want the search engines and users to see. Often, a website has too many keywords to be clumped together on the home page. With a list of terms, you can both inform and educate.

I gave a talk recently to my SEO Meetup about the 10 biggest SEO Mistakes. I discovered that there are way more than just 10, so I grouped them into three basic sections: Web Design; Title and Meta Tags; and Linking.
Of course the absolute BIGGEST mistake is not to do SEO at all, but I presume that you already know that.
Web Design
DON’T
Put a splash or doorway page on the website. This is a page with no text that a user has to click on to enter the actual website. We have all seen this, there is a big graphic, or a Flash movie, and a small “Skip Intro” button at the bottom somewhere. Why upset your users when they come in to the website? Remember, you only have 7 seconds to grab their attention.
Use frames on the site. An example is a website that is cut into boxes where the text scrolls down but the design stays put. This includes I-Frames. Fortunately, most designers no longer fool with frames, but i-Frames are just as bad. Try printing out a web page that has frames and you will get two blank pages and one of text. Which one will the search engine see? The blank ones.
Have a Flash movie on the first page. Most search engines cannot see Flash, and will not index your website as a result. Even though Adobe supposedly gave Yahoo and Google information on Flash, the programs cannot see your images. However, you can embed the Flash video in a static HTML page. This allows the search engine to index the page and your users still can see the lovely movie.
Use graphics with text in them (i.e. like a page header with your tagline in it). Again, search engines cannot see graphics and will miss the important data.
Have a lot of flashing and blinking animations on your website. This is distracting to the user and “so last century”.
Please do not try fancy navigation buttons. These often lead to confusing both the users and the spiders. You want to have straightforward, easy to read / see navigation links throughout the website.
DO
Have at least a paragraph of text on the first (or home) page. This allows the search engines to properly classify the site and helps the users as well (7 second rule).
Have your contact information at the bottom of each page or in a visible location (such as a Contact Us page). This boosts credibility.
Use your most important key terms in the text of the pages, so that the search engines and your prospective clients can find you.
Make sure that the navigation of the website is clear and simple to use. If a user cannot navigate your site, they will leave.
Make sure that there are no broken links on the website. This means checking back every few months.
Part 2 will cover Linking.
There are a lot of untruths floating around the Web about SEO. I often hear them when clients bring them up to me. New ebooks on SEO are constantly popping up with headlines like, “Rank First on the Search Engines!” or “Learn the Secrets that SEO people won’t tell you!”
Well, as an SEO guru (and I was a guru long before most of the others, LOL), I’ll tell you right now, the most important tag in your website code is the title tag.
The title tells not only the search engines, but your users what the website is about. It should be no longer than 60 characters, and should have your most important keywords in it. But, it needs to be a title, NOT a string of keywords stuck together.
Here are some examples of titles that I have recently placed on websites:
Jewell Entertainment: Your Agency for Unforgettable Events (this is for an entertainment agency that places talent at events)
Tamara Alter: Unique Gemstone Jewelry (a jewelry designer)
Arenson Office Furniture: San Diego’s Workspace Solutions (office furniture store in San Diego)
Grand Entrances: San Diego’s Finest Custom Entry Doors (‘nuf said)
Once Upon A Favor: Wedding and Baby Shower Favors (wedding and party favors)
Now, once the title is correct on the home page, it needs to change for all the inner pages in order to reflect content. So, on the About Us page, the title would say: Once Upon A Favor: About Us and so on.
A lot of people make the mistake of just repeating the same title tag over and over. It does not help your users find their way through your website.
This is an excellent post on how to explain why search engine optimization is so important to clients.
Apparently, everyone is now talking about and claiming that they can do search engine optimization. The amount of misinformation flying around the Web is amazing!
Search engine optimization is not easy, nor is it magic. It is a lot of hard work and keyword research and requires a deep level of understanding of both the search engines and their users.
I keep getting emails from marketers that says that this automated program or that software will do SEO for you. Unfortunately, many of these programs are actually a lot harder to use than just learning SEO.
Automated submission programs should be avoided (like the plague), and software often has a lot more bells and whistles to them than just doing the SEO.
Another problem is that software is rarely updated as fast as the search engines change. Unless you can find a program that does regular updating of itself, I suggest avoiding these sorts of programs.
