7 Web Analytics Metrics Mistakes
B2B Web Analytics Mistakes and Pitfalls |
 |
Many times, statistics from web analysis can be misleading. It is
all too easy to end up doing the wrong thing based on analysis of
website statistics. Here are mistakes we have discovered for the following
metrics:
- Number of Leads by Keyword
It is very important to measure conversions by keyword.
This lets you know where to focus your marketing efforts. However,
many B2B sites and especially those with high cost items have a
relatively small number of conversions. In addition, the conversion
may occur:
- During the 2nd, or later visits when the original keyword
used is now lost (due to cookie erasing, subsequent search using
product name, etc)
- By a coworker of the original searcher who lands directly
on site since the URL is now known
Since the numbers are small and may not be traceable to the original
search, in many cases it is statistically invalid to decide on actionable
items based on the number of leads by keyword. In those cases it
is best to find proxies for conversions. Possible proxy candidates
are time-on-site or engaging actions.
- Percentage of Leads
The percentage of leads from total visitors or any other
segment is not always relevant. In many cases the profit from a
B2B sale is big enough so that a good lead can justify the cost
of a campaign even though the percentage of leads is small. The
absolute number of leads is more important in this case. If you
see that the percentage of leads from traffic is going down but
the absolute number is going up--you can should go out and celebrate
your success.
- Absolute Number of Leads
Measuring the absolute number of leads can mislead you.
Yes, I know I just contradicted the previous point. Unfortunately
you may sometimes notice the number of leads is decreasing. Before
you panic, it is useful to measure the percentage of conversions.
This is because there are many times when seasonal or other time-based
factors impact total traffic. If we just measure absolute numbers
and we see a 50% drop in leads we start to panic. But if you see
that the percentage of leads
is consistent over the last few months you know that the reduction
in number of leads is due to a drop in traffic. You should then
analyze to see if the reason is seasonal or other factors we have
no control over. If it is seasonal, we can relax--although we should
still try and improve the percentages. If it is a factor we do have
control over, we can then start to panic and work to rectify the
situation.
It is useful to measure percentage of conversions to use as an early
warning sign, however our main goal should be to increase absolute
conversions until the expense of increasing them outweighs the profit.
- ROI
This important metric has great PR but it is undeserved.
As long as you are profiting from a campaign, the return on investment
should not be use to eliminate ad campaigns. You can use it:
- If you need to reduce your advertising budget this metric
then becomes necessary in order to guide you to which areas
it is best to reduce the budget.
- To measure your optimization efforts
- Number of Downloads
Not all downloads are created equal. Whitepapers are typically
downloaded earlier in the sales cycle. In addition, you may get
many non qualified people downloading the white paper who are interested
in the subject. Data sheets, on the other hand are usually downloaded
by people later in the sales process and who want to see detailed
specifications of your product.
By measuring downloads you are lumping these and other different
segments together. Best to measure whitepaper downloads separately
from data sheet downloads. An upsurge in white paper downloads in
October may be because students are studying the subject described
in your white paper. On the other hand, an upsurge in data sheet
downloads is usually great news--unless you find out that it is
your competitors doing all the downloading.
- Using Numbers that are Statistically Valid
In many cases metrics do not have enough information to
be statistically valid. Unfortunately there is a tendency to want
to come to conclusions fast. This could be because:
- You want to prove something and are over eager to bring the
testing (with the results you wanted) to a conclusion
- There is pressure to present actionable items to others
Avoid the pressure. I have seen many tests where the results flip
flop once or twice before the numbers are valid.
- Experience and Knowledge.
Numbers are great and no one loves them more than me. However,
they are just numbers and have many disadvantages:
- There is still a lot of information they don't include. For
example they don't explain why people do things
- There may be mistakes in the data
- The conclusions may not make sense and by being stubborn
and digging deeper you can usually find the reason
- In addition, they can be manipulated to prove preconceived
ideas-sometimes
unconsciously. As my seventh grade math teacher
said: Figures don't lie, but liars figure
These are some of the web analytics pitfalls and mistakes we have
come across. I am sure there are many more. If you have any, I would
love to hear from you.
