Search engines attempt to rank results for a given search based on their relevance to the topic, and the quality and reliability a site is judged to have. Google, the world’s most popular search engine, uses an ever-evolving algorithm that aims to evaluate sites in the way that a human reader would. This means that a key part of SEO involves ensuring that the website is a unique and relevant resource for readers.
A solid content marketing and SEO strategy is also the most scalable way to promote your business to a wide audience. And this generally has the best ROI, as there is no cost per click — so you are scaling your marketing without directly scaling your costs. This kind of SEO strategy is not right for every business, but when it is a good fit, it’s almost unbeatable.
While most of the links to your site will be added gradually, as people discover your content through search or other ways and link to it, Google understands that you'd like to let others know about the hard work you've put into your content. Effectively promoting your new content will lead to faster discovery by those who are interested in the same subject. As with most points covered in this document, taking these recommendations to an extreme could actually harm the reputation of your site.
Early versions of search algorithms relied on webmaster-provided information such as the keyword meta tag or index files in engines like ALIWEB. Meta tags provide a guide to each page's content. Using metadata to index pages was found to be less than reliable, however, because the webmaster's choice of keywords in the meta tag could potentially be an inaccurate representation of the site's actual content. Inaccurate, incomplete, and inconsistent data in meta tags could and did cause pages to rank for irrelevant searches.[dubious – discuss] Web content providers also manipulated some attributes within the HTML source of a page in an attempt to rank well in search engines. By 1997, search engine designers recognized that webmasters were making efforts to rank well in their search engine, and that some webmasters were even manipulating their rankings in search results by stuffing pages with excessive or irrelevant keywords. Early search engines, such as Altavista and Infoseek, adjusted their algorithms to prevent webmasters from manipulating rankings.
