| In the last couple of months I've been working on | | | | comprehensive webtraffic statistics website available |
| prospecting the Latin American market for Real | | | | for free use. Even though it's not statistically |
| Estate WebPortals. In my research I've found that at | | | | accurate (Its sampling method is not representative) |
| some point I needed to forecast traffic (number of | | | | is the closest we have to an overall traffic ranking |
| unique users per month) in each of the studied | | | | system . It tends to work pretty well with websites |
| countries in order to have at least an approximation | | | | with a "Traffic Rank" higher than 100.000. |
| of the revenue income from Advertising. | | | | - Ranking.com: Provides information in a very similar |
| In my research I did not find what I was looking for: | | | | way than does: Traffic Rankings, Number of users |
| a simple tool or website where if you pasted the | | | | per Million, trend graphs, etc. |
| URL it gives you an estimate of monthly visits/users | | | | Given that there wasn't such a tool, I decided to |
| or page views. The only website that does this kind | | | | creat one myself and I developed an Excel Model to |
| of estimation is however, after extesive comparison | | | | predict website Traffic for any site. The model I |
| of its results and real data that I managed to get, I | | | | came up with is an statistical function (the average |
| have to say that the error margin of this site is huge. | | | | of a linear function with a 2nd degree polinomic |
| The variability of the estimates (compared to real | | | | function) and predicts the number of users based on |
| data) that this website has in its results is so big that | | | | Alexa's reach. This model, with links real stats (past |
| I cannot recommend it for traffic estimations or | | | | real number of users of selected websites) to |
| traffic forecasting. | | | | estimate users of any website, based on its reach. In |
| Although I couldn't find exactly what I was looking | | | | some cases, because Alexa's information is not |
| for to accurate predict traffic, In the search process | | | | accurate always, the "Reach" has to be "translated" |
| I found some interesting tools that can be useful: | | | | into a relevan number before being plugged into the |

| does not provide the actual number of users or | | | | Although it still needs a lot of work, so far the |

| search volumes and compare relative search volumes | | | | I can forward the Excel file on request and for free, |
