Real-Time Search
Theoretically speaking, real-time search across the Internet is virtually impossible.
What is possible is collecting a subset of newly posted information across an array of
sites and making this available relatively quickly.
For real-time search to be viable, it has to address many different factors but answer
one basic question: what is relevant at this moment? The viability of real-time search
relies on its heavy use of the social networking community sites as well as in designing
algorithms to filter junk versus relevant, important content on the fly.

Twitter uses a different kind of keyword matching when producing its
search results. If you search for watching TV, you will get results that contain both
terms.
Twitter search produces up to 1,500 tweet search results broken down to 15 tweets per
page . Even the last search result out of the 1,500 can be only a few
minutes old, depending on your search keyword. For hot topics, this may even go down
to a few seconds. Twitter’s search is case-insensitive. Twitter does not have any fancy
search commands like Google does, but in time it is expected that Twitter will catch
on in that department.

Search Engine Marketing
Google AdWords is the number one SEM platform on the Internet today, and is the
subject of many books. Although we cannot cover every single detail of AdWords in
this chapter, we will spend some time on the most important features of the platform.
Google AdSense is the extended arm of AdWords. Whereas you can use AdWords to
test, validate, and improve your keyword research, you can use AdSense to earn income
from Google by showing contextual ads. You can also use AdSense ads on your target
web pages to see whether relevant ads will show up to further validate your targeted
keywords.
