Natural Listings – Web page listings that appear in a search engine’s results, based on the engine’s own proprietary algorithm. The website/web page owner has not paid for these positions in the results, and the listings are ranked in order of relevance to each search query with the most relevant listed first.

As long as a listing has achieved its position naturally (not paid for), it is a “natural” or “organic [link:]” listing.

Natural Search – See Organic Search Results [link:].

Netscape – Originally a company that created a popular web browser by the same name, Netscape is now a social news site similar to Digg.com [link:].

Niche – A topic or subject which a website is focused on.

Search is a broad field, but as you drill down each niche consists of many smaller niches. An example of drilling down to a niche market:

  • Search
  • Search marketing, privacy considerations, legal issues, history of, future of, different types of vertical search, etc.
  • Search Engine Optimization, Search Engine Marketing, Pay-Per-Click
  • Link building, keyword research, reputation monitoring and management, viral marketing, SEO copywriting, Google AdWords, information architecture, etc.

Generally it is easier to compete in small, new, or underdeveloped niches than trying to dominate large verticals. As your brand [link:] and authority [link:] grow you can go after bigger markets.

Niche Directory – Directories which focus on or niche topics, specialist sectors, restricted regions, or single languages. One type of niche directory with a large number of sites in existence, is the shopping directory for example.

Nofollow – Attribute used to prevent a link from passing link authority. Commonly used on sites with user generated content, like in blog comments.

The code to use nofollow on a link appears like:

<a href=”http://www.example.com.com” rel=”nofollow”>anchor text</a>

Nofollow can also be used in a robots meta tag to prevent a search engine from counting any outbound links on a page. This code would look like this

<meta name=”robots” content=”noindex, nofollow” />

Noscript Tags – The tags are used to supplement Flash [link:], and can be a great way to introduce content to supplement 100% Flash websites, where there otherwise would be none. You have to be careful with how you use it, but if used in a white-hat, non-malicious manner it can be an effective way to optimize Flash websites.

Here is an example of what Noscript Tags look like:

<noscript>
<p>Your Supplemental Content</p>
</noscript>

Navigation bar (nav bar)

a web site’s navigation icons, usually arranged in a row down the left hand side or along the top that plays crucial roles in directing spiders to the site’s most important content and in getting site visitors to go deeper in the site

Negative Keyword

Negative Keyword is a term referenced by Google AdWords and is a form of keyword matching. This means that an advertiser can specify search terms that they do not want their ad to be associated with.

For example, if you add the negative keyword “-nike” to the keyword “running shoes”, the ad will not be displayed if a person searches upon the term “nike running shoes”.

Negative keyword matching ensures that only qualified traffic is clicking upon advertising.

Negative SEO

The act of demoting a page or site from the SERPS. Most often used against a competitor that is above your site in the SERPS but can be used purely for fun.

Noframes tag

alternative non-framed HTML on a frameset page for very old, non-frames capable web browsers and search engine spiders. Placing good keyword-rich text in noframes tags is a good idea if your site is framed, but a much better idea is to ditch frames altogether and rebuild the site properly. A framed web site is not search engine friendly as long as it uses noframes tags.
