Just browsing and saw your query re Adwords. I have a site promoting a wedding venue and for years half the traffic was organic, half Adwords. My spend on Adwords about £12,000 a year I suppose, with the main spend in Jan and Feb which is when more people are looking for venues (having got engaged over Xmas), New Year new start etc. Problem was even with separate landing pages with their own enquiry forms, people move off the landing page and around the site, so by the time someone books a viewing, I had no idea whether they were Adwords sourced or Organic sourced. I tried Adwords for special offers with the Adwords visitors landing on a hidden page not visible to organic traffic, but saw no viewings from the Adwords landing page. I wondered if Adwords even worked at all. So early this year I diverted all the Adwords on to a separate website which had no organic traffic to speak of but was similar to the main site. I removed all the links between the two websites, so an Adwords visitor to the separate website could not link to the main site. And guess what, NO enquiries came from the separate site. So after years of using Adwords, I realised Adwords does not worked. OK so I saved myself £12k a year, and now only rely on organic traffic and referrals from facebook etc. But I would love it if Adwords actually worked, as I could then get a nice measurable return on investment and grow my business just by advertising more. Yes I used a specialist Adwords firm also to get the key words right. I now know Adwords is a marketing illusion. Most people do not 'get' that Adwords does not work (at least not for our service). You see lots of visitors to yourwebsite, but the ones buying are the organic visitors not the paid for visitors. I do still use Adwords for a 'last minute wedding' offer, but spend just £5 a day or so on that campaign. Why is this so? I suppose organic traffic is just better optimised than Adwords traffic where you are trawling for clicks from the wrong people.
