Then the most important is getting links from other pages with the keyword in the links from other good sites to your page.
As for using red colors? I never heard that before either but I personally try to stay away from using fonts and colors unless I have to.
Getting #1 for term X is presumably not the real goal.
Getting traffic relevant to your offerings is.
Don't get hung up on being #1 for your "dream keyword" - optimize for a large number of relavant terms that get some traffic.
Ie - getting #1 for "aquamarine widgets" might get 10x the traffic you'd get for "green widgets" at #15.
More specific tip - make sure your pages have enough unique content to plausibly be saying something. I've watched "focus" pages move up in rank substantially by just adding another 100 words of content.
It might seem like I am being flippant, and I am, but I'm also giving good advice.
If you are fixated on #1 for a specific term, instead of trying to improve all your rankings and traffic, it increases the likelyhood that you will do something stupid that will come back to bite you later. Unless, of course, you are playing with throw-away domains.
Depending on what the term is, it might be as easy as cleaning up your internal linking, or it might be impossible if you aren't a .gov or .edu site.
walkman, if this does happen (i think it did with one of my sites..). what is the fix? patience? scaling back? all the content added was relevant and there are a very mild use of adsense.
If your backlinks rocket for a double of weeks and then stabilize or decrease, a Google penalty will be pretty potential.
If your backlinks keep increasing, then Google may simply consider that your site is very interesting for the general public.
Just my 2 cents... Good luck.
