my site got online before. get indexed by google for homepage.(a page site) but server down for weeks. now, google never access my site. i see no bot access my site. does it mean google banned my site? i still have backlinks.
Google won't ban you easily. Just don't get your site offline for too long. You can now start to add in contents and ping Google about it to notice them about your update.
Its just because your site have been down for a weeks, don't lose hope just continue your seo task and this time you have to double it! And of course the design and the color of the site are advantage for the visitors, so I offer you a Free Downloadable Wordpress Themes just click on my sig! Good Luck!
submit to few social bookmarking sites and google bot will keep coming back to your site. you can also keep building backlinks and attrack google bot but SB submission is the fastest way to bring google bot to your site. i got one of my site indexed by google in less than 15 minutes
I think you should use google sitemap and work out to create some quality content to attract google spiders.
