Depending on what study you read, you will get different guidance as to how much of the overall traffic for a particular key-phrase your site will get depending on its rank in SERP for that phrase. Most studies seem to suggest that sites will get at least a 400% boost in traffic from a particular key-phrase if they improve their rank from 2 to 1. This seems logical as most will click on the top result and substantially less would be expected to click on the second result. Interestingly, position number 10 is often believed to be more valuable than number 9 as people click on the bottom ranking page just before they had intended to move to page 2.
This morning, I decided to analyse the traffic from a particular key-phrase for a site that we manage. After a long stint in position 2, we have now secured top spot so of course I was interested to see how this impacted on traffic. As per the graph below, getting top spot has made a big difference but certainly not of the order of 400%. Based on cold hard data below, we see an increase in the region of 100% – hardly insubstantial but far less than the conventional wisdom would suggest.
As the above is just a single example, I decided to look at another example with similar characteristics. Again, after a lengthy spell in postion 2, we recently hit top spot. We achieved top spot on 18th July. Have a look at the graph below of traffic from this keyword.
You will note that before achieving top spot, we were struggling to break 45 visits in a single day but now that we have achieved top spot, we are approaching 90 daily visits from this phrase. However, daily visitor numbers, as per examples above have increased by about 100% so the difference between top spot and position 2 seems to be, based on the above, in the region of 100%.
I subsequently decided to look at how the above data fits in with the data provided from the Google Keyword Tool. This tool tells us that there are approximately 330 daily searches for the key-phrase in the bottom graph. As we are averaging around 150 daily visits, we are getting about half of the total demand for this key-phrase – the rest of the demand likely goes into Adwords listings. In the top graph, the Google Keyword Tool advises that there are approximately 500 daily searches for this phrase. Now that we’re top spot, we’re getting in the region of 100 visits per day or about 20% of total demand. This discrepancy is likely attributable to the fact that the keyword tool provides only loose estimates as opposed to actual numbers.
So, to sum up, the difference between top spot and position 2 is approximately 100%. From top spot, your site will hoover up around 20-50% of total demand so we know that from position 2 you can expect about 10-25% of total demand.
