White Hat Methods and Practices
White hat methods of SEO involve following
the search engines' guidelines as to what is and what isn't acceptable.
Their advice generally is to create content for the user, not the search
engines; to make that content easily accessible to their spiders; and
to not try to game the system. Often webmasters make critical mistakes
when designing or setting up their websites, inadvertently "poisoning"
them so that they will not rank well. White hat SEOs attempt to discover
and correct mistakes, such as machine-unreadable menus, broken links,
temporary redirects, or a poor navigation structure.
Because search engines are text-centric,
many of the same methods that are useful for web accessibility
are also advantageous for SEO. Methods are available for optimizing
graphical content, including ALT attributes, and adding a text caption.
Even Flash animations can be optimized by designing the page to include
alternative content in case the visitor cannot read Flash.
Some methods considered proper by the
search engines:
- Using unique and relevant
title to name each page.
- Editing web pages to replace
vague wording with specific terminology relevant to the subject of the
page, and that the audiences that the site was developed for will expect
to see on the pages, and will search with to find the page.
- Increasing the amount of unique
content on a site.
- Using a reasonably-sized,
accurate description meta tag without excessive use of keywords, exclamation
marks or off topic terms.
- Ensuring that all pages are
accessible via anchor tag hyperlinks, and not only via Java, Javascript
or Macromedia Flash
applications or meta refresh
redirection; this can be done through the use of text-based links in
site navigation and also via a page listing all the contents of the
site (a site map).
- Allowing search engine spiders
to crawl pages without having to accept session IDs or cookies.
- Developing "link bait"
strategies. High quality websites that offer interesting content or
novel features tend to accumulate large numbers of backlinks.
- Participating in a web ring
with other quality websites.
- Writing useful, informational
articles under a Creative Commons
or other open source
license, in exchange for attribution to the author by hyperlink.
Black Hat Methods
Main article: Spamdexing
"Black hat" SEO are methods
to try to improve rankings which are disapproved of by the search engines,
typically because they consider such methods deceptive, and unrelated
to providing quality content to site visitors. Search engines often
penalize sites they discover using black hat methods, by reducing their
rankings or eliminating their listings from the SERPs altogether. Such
penalties are usually applied automatically by the search engines' algorithms,
because the Internet is too large to make manual policing of websites
feasible.
Spamdexing is the promotion of irrelevant, chiefly commercial,
pages through deceptive techniques and the abuse of the search
algorithms. Over time a widespread consensus has developed in the industry
as to what are and are not acceptable means of boosting one's search
engine placement and resultant traffic.
Spamdexing often gets confused with white
hat search engine optimization techniques, which do not involve deceit.
Spamming involves getting websites more exposure than they deserve for
their keywords, leading to unsatisfactory search results. Optimization
involves getting websites the rank they deserve on the most targeted
keywords, leading to satisfactory search experiences.
When discovered, search engines may take
action against those found to be using unethical SEO methods. In February
2006, Google removed both BMW
Germany and Ricoh
Germany for use of these practices.[9]
Cloaking is the practice of serving one version of a
page to search engine spiders and another version to human visitors.
Page Quality and Ranking
When a site has useful and engaging content,
there's a good chance that other webmasters will naturally place links
to the site, increasing its PageRank and flow of visitors. When visitors
discover a useful website, they tend to refer other visitors by tagging
or bookmarking the page, linking to it, and sending others links to
it by email or instant message.
As a result, SEO practices that improve
website quality are likely to outlive short term practices that simply
seek to manipulate search rankings. The top SEOs recommend targeting
the same thing that search engines seek to promote: relevant, useful
content for their users.
