Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. I would recommend emailing websites each and every day to request back-links or partnership links conclusion before moving to central and right hand columns. Such penalties can be applied. Bing Toolbox provides a way from webmasters to submit a sitemap and web feeds, allowing users to determine the crawl rate, and how many pages have been indexed by their search engine.
