These terms will help you understand some of the concepts used in this
RoCkHaCkErZz. We list them in alphabetical order and some of them are a bit
abstract but please soldier on:
x AJAX is a number of techniques to create client-side asynchronous
web applications brought together by JavaScript. Rich features
using AJAX are popular because they usually improve the user
experience by efficiently refreshing content. AJAX is however an
issue for Google’s crawler because it cannot read its content.
Google expects that developers carry out some extensive hacking
to deal with AJAX (see section “Make AJAX crawl-able” below).
x Backlinks or inbound links are links from external websites
pointing to another website as opposed to internal links from
pages on one website to other pages on the same site. Backlinks
are not to be confused with the links to search results on Google
SERPs.
x Corpus is a collection of documents in a machine-readable format,
usually text. Examples of corpora (plural of corpus) are dumps of
databases of any nature and format, the scraping of a website or
any number of websites, etc.
x Crawler or web spider is a bot programmed to browse
systematically websites for the purpose of indexing, like Googlebot
x CTR stands for Click Through Rate or clicks on a search result
divided by the number of impressions (or how many times it
showed on any SERP)
x Document is a piece of text or rich media that can be accessed and
stored individually. An example of a document is a webpage or a
downloadable pdf file.
x Graph is the interconnection between documents (vertices) by
edges (links). An example of a graph is the network of websites
linked with each other.

project modelling the Internet in 2003. Colours modified from the original representing
different regions of IP addresses like Asia Pacific, Europe, North and South America, etc.
The concept of graph is a key concept in SEO. Many projects of new
websites usually start their life as the output of a number of
functionalities and ad-hoc extensions, rather than a body of
interconnections. Search engines and SEOs however think of websites
and actually the entire Internet as a graph.
x Information Architecture (abbreviated as IA) is the organization of
documents and their connections. Websites are, in terms of IA,
dynamic and connected structures of bot-readable content.
Rockhackerzz.blogspot.com is mostly applied IA for search.
x PageRank is a metric used by Google to determine the importance
of an element (e.g. document, graphs or parts of them). It is one of
more than 200 factors used to determine rankings of search
results on Google. SEOs tend to prefer concepts like link juice or
authority and new metrics to Google’s PageRank.

x SEOs or search marketers are professional practitioners of SEO.
x SERP is the acronym of Search Engine Results Page or the list of
links to results that search engines return in response to a user’s
query, e.g. http://www.google.com/#output=search&q=serp
x Silos are groups of subject-specific content on websites, e.g.
categories separated as tree or sub-categories and detail pages.
Vertical silos are frequent in tree structures where category pages
are linking down to sub-category pages. The webpages under silos
are hardly linked with webpages of other silos, i.e. there are few or
no transversal or cross links across silos.
