How to start more deep seo.

[levalencia1]

Okay, lets say that I already fixed all my technical seo stuff. All my crawl errors and warnings are gone. Now I really want to start seo so I have a few questions.

1. I know I should work based on a page and not on a domain, so it means I should choose which keyword to optimize each page for? only one keyword per page? or it might be more?

2. Some keywords are very competitive for me, example for my site www.theprinterdepo.com, the best keyword to rank would be printers, but it would take years a beginner to do that, what should I do?

3.  If highly competitive keywords are not an option, which keywords shuold I use? the ones that have more global monthly searches?

Thanks

I agree with Ryan - you need a strategy. I think one of the biggest mistakes we can make when targeting SEO keywords is going too broad and hoping that we can capture things that quite honestly aren't the right fit. You really have to know them, their terminology and how they search. The article link Ryan shared is a great layout for how to go about a sound strategy, which will eventually answer your questions.

However, as for the global monthly searches - personally, I say ignore that. Check the "exact" phrase box and look at the local monthly searches. I want to have an idea of how small of an audience I can end up with if I select certain words. It's a very different perspective to find out a word you thought was really popular actually gets 170 searches a month and at best  I can only hope to capture a percentage of that.

I think what you're really talking about is crafting an SEO strategy.  I'm a big fan of persona-driven strategy development.  Go here:

This is the first of eight posts from a former Yahoo Media on SEO strategy.  It's going to force you to carefully consider your target audience, do a lot of competitive research, think about content, etc.  Yes, it's a lot of reading, and a lot of effort.  It's worth it.  Trust me.
