What should a web site cost you?
Archive - Originally posted on "The Horse's Mouth" - 2009-06-16 18:52:19 - Graham EllisI don't know, but I was asked my opinion on website costs for a government department (the Department for Transport) which have been revealed in a Freedom of Information request here. And I have compared the figures given to the figures for our main web site (www.wellho.net) and for the volunteer "First Great Western Coffee Shop" forum.
Quoting the FOI pre-amble:
A copy of the information requested following an agreed reduction in scope is enclosed. A. Unique visitor data and separate staff costs for adding and updating content on the Department for Transport corporate website are not available for the financial year 2002-03 but have been provided for subsequent years.
In keeping with the spirit and effect of the Freedom of Information Act, all information is assumed to be releasable to the public unless exempt. The Department will, therefore, be simultaneously releasing to the public the information you requested, together with any related information that will provide a key to its wider context.
The three most recent years are as follows:
| dates | website costs (pounds) | staff costs (pounds) | unique visitors |
|---|---|---|---|
| 1 April 06 - 31 March 07 | 1,467,525 | 59,116 | 2,515,139 |
| Commentary 06-07 - These costs include accessibility and usability testing, costs to develop a new visual design, costs to develop new information architecture, system build costs and content migration costs to a new Content Management System. | |||
| 1 April 07 - 31 March 08 | 715,485 | 60325 | 3,571,614 |
| 1 April 08 - 31 March 09 | 749,819 | 60799 | 3,478,952 |
| Please note that the above costs include resource costs, capital expenditure and depreciation costs. | |||
So how reasonable are those figures?
Looking at our own website (http://www.wellho.net) the last year's figures are as follows:
| dates | website costs (pounds) | staff costs (pounds) | unique visitors |
|---|---|---|---|
| 17 June 08 - 16 June 09 | <1,000 | (unknowns/see_note) | 2,284,220 |
| These website costs are inclusive costs for a server, the price of which includes resource and depreciation, and our supplier will recover capital expenditure from within that amount too. We do not have full time web and development staff - you may estimate 1/3 of a the costs of a person as a rough guess. I have used a high figure in the comparative table below. | |||
And looking at the "First Great Western Coffee Shop", I have six months of data as follows:
| dates | website costs (pounds) | staff costs (pounds) | unique visitors |
|---|---|---|---|
| 20 December 08 - 16 June 09 | <250 | volunteer | 40,565 |
Realistically, the number of unique visitors to "The Coffee Shop" in a year would be between 50,000 and 60,000 ... (educated estimate) as it's a web site where people come back time and time again. The number of individual requests to the server in that six month period was 4,785,623 indicating 118 requests per visitor. That would extrapolate to around 9,200,000 requests in a year
The figures for www.wellho.net are slightly depressed (circa 5%) by a server move last July. The number of individual requests was 44,918,001 - indicating 20 requests per visitor.
These two servers are extreme cases; a typical figure may be perhaps 50 accesses per unique visitor, giving 173,947,600 accesses to the DfT website. Let's come up with a grand comparison:
| Annual Accesses | Annual Visitors | Annual Cost | Cost per access | Cost per visitor | Site |
|---|---|---|---|---|---|
| 173947600 | 3478952 | 810618(pounds) | 0.466(pence) | 23(pence) | Department for Transport |
| 44918001 | 2284220 | 21000(pounds) | 0.046(pence) | 0.91(pence) | Well House Consultants |
| 9571246 | 55000 | 500(pounds) | 0.005(pence) | 0.91(pence) | First Great Western Coffeeshop |
You could (you should!) pick many differences between our web site and that run by a government department. On one hand, they have to be so much more careful to avoid a single mistake and to track data ... and on the other hand they should have the benefit of quantity behind them. In other words, setup and maintenance costs should be defrayed over more visits, leading to a reduced rather than an increased cost per visit.
My analysis of my own systems was done using Perl (what else! - a heavy data handling task, one off programs that won't have a long maintained shelf life ... the language fits).
Here's the program for counting unique visitors in a day:
#!/usr/bin/perl -na
$c{$F[0]}++;
END{ print ("Unique visitors",0+keys(%c),"\n"); }And here's the program for going through a year of log files (they happen to all be in one directory, start with ac_, and there are no other files starting that way in the same directory!
#!/usr/bin/perl
foreach $fl (glob("ac_*")) {
print "$fl\n";
$nf ++;
open (FH,$fl) ;
while (<FH>) {
@F=split;
$c{$F[0]}++;
$lns++;
}
}
print ("Unique visitors in $nf days - ",0+keys(%c)," / accesses $lns\n");
