dont make your text content an image.. crawlers cant read your content.. create a sitemap and send to search engines so they'll crawl your site and see whats your content.. title tags, meta descriptions, and meta keywords are the main metas used.. create a title that best describes your site.. in meta descriptions, describe or elaborate what's the purpose or what products or services we can see there and lastly, put all the possible keywords that targets your site.. hope I've helped you in your Inquiry..
