The single most necessary methods in gaining better site's ranking in Google search results is to make sure that its full of rich information which consists of relevant keywords, used properly, that show the topic of your content.
Nevertheless, some webmasters try to boost their page's ranking and attract site visitors by generating pages with lots of words but almost no authentic content. Google will take action against domains that attempt to rank more highly by just displaying scraped or other auto-generated pages that do not add any value to users.
- Thin affiliate sites: These sites collect pay-per-click (PPC) revenue by sending visitors to the websites of affiliate marketing programs, while offering almost no value-added content or service to the user. These websites normally have no original content and could be cookie-cutter sites or templates without any unique content.
- Doorway pages: Pages created only for search engines
- Auto-generated content: Content generated programatically. Usually this will contain random paragraphs of text which make no sense to the audience but that could contain search keywords.
- Scraped content: Some webmasters make use of content taken from other, more reputable websites on the idea that improving the number of web pages with random, irrelevant content is an excellent long-term strategy. Only scraped content, even from high-quality sources, might not provide any added value to your users without additional useful services or content given by your site. It's worthwhile to take the time to create original content that sets your site apart. This will keep your visitors coming back and will provide useful search results.
There is no problem in being an affiliate if you create some added value for your users and create useful content that offers a user a reason to visit your website. For instance, you may create product reviews, ratings, and product comparisons.
