though everybody know that SEO is correct, but if you consider need SEO or not? Its really depends on how rush or how effective on your SEO of the website! Is it gonna be cost-effective, you can always spend your whole lifetime on fine-tuning on your website words by words, tag by tag...

but for me...seo is just a way to get some traffic while there are actually much more other ways more effective besides spedning your time and money on SEO things
