According to Matt Cutts Google ranks pages according to relevance and reputation. Why should you believe him? well because he is the head of the Google Webspam team. When it comes to search; Google Search, Matt Cutts is the man to listen to. So listen to him.
Reason 1: You can't become relevant over night
Being relevant is something you acquire over time. Measuring relevancy is something that gets tweaked over time. So by nature Google's ranking algorithms will and must change over time to maintain relevant rankings and improve their measure of relevancy. So how can you, you or you guarantee relevancy? I can promise you the sun will rise from the east tomorrow (if it didn't then SEO is the last thing on anybody's mind), but can anybody promise you a million dollars tomorrow? Sure someone can; somebody very generous and with a million dollars to give away. For SEO that generous billionaire would be Google, but then if they do, can they remain relevant? You get my point.
Reason 2: You can't become reputable the next day
Building any reputation takes time; even a bad reputation. Your website's reputation is critical for ranking on the SERPs. The more PageRank the higher you rank. You get more PageRank by getting inbound links from others with high PageRank. Quality over quantity. 1 million times zero is still zero.
Reason 3: Because Matt Cutts said so
According to him, the best SEO strategy is adaptive SEO. Just like any optimization algorithm, you make gradual improvements and take a measurement against the objective function. Rinse and repeat, but don't get overly obsessed with it; quit when you hit the point of diminishing returns, then try something else.
This process obviously takes time and research. But thanks to Google they give you all the tools and information you need to rank high on the SERPs.
For my blog I follow three simple rules:
- When I write about something, I put myself in the shoes of someone looking for the information I am about to write on. I make a list of these keywords and naturally include them in my post.
- Every month I use Wordle.net to generate a tag cloud of my blog. This gives me a good idea about the keyword distribution and whether I have enough keywords on the topics I would like to rank high on.
- I make sure each of my posts' URLs contain the main keywords. This step is crucial.
With these three steps, I rank pretty well on some topics:
Now, have I got a DEAL for you... : )
