I'm working on my website which I am hoping to become an authority site one day in the future. The niche is pretty saturated, but there's not an authority website yet. There's hundreds of thousands of websites, but none of them utilize SEO or even offer anything, they are just pretty much text tossed out into the WWW for no reason whatsoever. You see the top links on google for this niche changing constantly, so I'm trying to secure a top-3 spot. I'm writing tutorials on my page, as my main niche is education, I supply people with a ridiculous amount of learning and I'm basically the most thorough and quality provider for this information you can find. I had just finished my first tutorial and It's a little over 7,000 words long. This includes snippets of programming code, and utilization of my keyword. I'm using wordpress and my YOAST plugin is stating that the SEO is good, but I'm just wondering if this will effect my first-page chances, because it's so long. I'm always reading that 500-600 word pages are the best. I have numerous pages with 4k+ words on it.
