The main problem with SA is that they are not showing up well in search engine results. For instance, I Googled machin stamp which I know should produce results for SA. There were 107,000 Google results for this but I trawled through the first 21 pages of them (210 results) and not a mention of SA at all. If a search does not come up within the first couple of pages on a search engine people tend not to wade much further in - in fact it's generally accepted that if you're not listed on the first page you're not seen. I've emailed the SA folks and made some suggestions as to how they may improve their search engine ranking/results - without those results the message is not getting out to the majority of internet users that there is an alternative to you-know-where - and free listing etc is fine but it needs buyers to know where those listings are as well!
