How do you know if your web site is good for your business?
By first answering the question: "Why do you have a web site?"

Knowing why you have a web site in the first place will go a long way towards helping you decide what kind of web site you need, or whether or not the web site you already have is good for your business.

The real 'trick' to SEO is to make your web site legitimately more attractive to your target audience than your competition. Identify your competitive edge and then talk about it using specific terms not generalizations on your home page. There is nothing more successful than good keyword rich text placed on your home page - when good search engine placement is the goal.

Multi-language web sites are fairly common in Canada due to our 2 official languages. If you do business across this country, you may be tackling the French/English question as well:
How do you present 2 languages on one web site?

A common way is to use an intro/splash page that solely offers a choice to go to the French site or the English site (as demonstrated here: http://www.compost.org).
Now, if you have been reading along, you will already know that not having text on your home page is an SEO impediment. However, the splash page technique has other drawbacks as well:

1. It requires one more click for the visitor to get to useful content.
2. Once you are on an internal page, you can't switch languages. You may think this is OK, unless you know that Francophones often search in English because of the greater number of English-language sites. If they land on one of your internal English pages, they may not even realize you have a French version of the site - since they never saw the home page!
3. This method does not lend itself to the idea of multi-language domain names.

Back2Front Recommends:
The solution we propose to our clients is to have "English / Français" links at the top of the menu bar on all pages. Here is an example taken from one of our clients: http://savingenergy.ca.

Notice how you can easily switch from one language to the other from any page of the web site, and how you can get directly to useful content with no extra clicks needed.
You can solve the problem of "which language is the default?" by acquiring two domain names (one in English and the other in French). This has the added benefit of allowing you to advertise your site in the appropriate language in language-specific situations (such as French news papers, etc).
Most importantly, you can avoid the negative impacts that a splash page can have on your user interface and SEO.
