Anyone who still follows manual methods of extracting data from websites is following an antiquated process. He wastes time, money and effort in the process while gaining far less than they would if they used online web scraping tools.

2. •Website owners have put in place protection prevent access to
sensitive data or display data dynamically and in a way that can be
viewed but not saved or downloaded.
•Some websites have password protection or require user registration.
•Some websites have automated tools to monitor user activity and will
block user IP if attempts at data downloading are detected.
•The amount and variety of data is stupendous and the number of
websites is staggering. It is simply impossible or far too time-consuming
to visit each site manually, download data if possible and
then refine it into a usable format.

3. The smart thing to do is enjoy
the benefit of computer
technologies and find web
scraping software online that
will automate the process. In
addition, the software will do it
intelligently, almost simulating
the way human minds work.
What is more, the software will
order and refine data into a pre-defined
format. A wish list of
what is required in a data
scraping software would read
something like this:

4. •An easy to use interface, even if it is web based, that will allow
users to input keywords and further options to add command line
options for exact matches.
•Specify URLs or simply keywords and let the inbuilt web crawler
trawl websites to find data.
•Let the software download data and then organize it into a format
that is ready to be used, stripped of tags and extra text. What users
get is pure data.
•Crawl to all website regardless of whether they are password
protected or require user registration and log ins.
•Configure once, use many times by saving parameters to a theme
that can be applied to future searches.

5. Not all web scraping software online are equal. Some have limitations in
that they cannot access image data or audio or even video. Some may
find tables restricting. What users need to look for in online web scrapers
is that they must be versatile and easy to use while being fast and
accurate at the same time. The objective is to get maximum amount of
quality data with the minimum inputs in terms of time and labour.

6. Does it cost much? There is a
cost to everything. However,
the user must view it in the
right perspective. If he were to
spend time and labour, he must
factor in costs of such efforts
and balance these against the
money he spends on services to
get quality and voluminous
data. He could consider the
value of productivity he
achieves by devoting the time
saved to other more pressing
tasks. In balance it will be seen
that using online web scrapers
is more cost effective.
