Does anybody know if there is any way to get the total number of daily unique visitors on a given period of time (e.g. a month) in Google Analytics?
(normally Analytics would just show the number of unique visitors for the month and not the sum of unique daily visitors in that amount of time).
Google Analytics has not such metrics as daily, weekly, monthly etc. unique visitors, it only has "unique visitors over selected time period". And you can't use it anywhere, since GA is visit based and not visitor. If you really want to measure unique visitors over a time period, use custom variables.
Make a custom report and under the filters tab select "Visitor-"Visitor Type" to get new and returning customers. A "new" customer is someone who accesses the website for the first time during your selected data range, and not the first time someone views your website (unique). You can read more about New/Returning vs. Unique Visitors here.
You can do this by setting up a custom dimension and send a unique id for every user in this dimension. Ensure not to send email/twitter handle etc as this ID, since they violate the privacy terms of Google Analytics. Ideally this ID is a unique internal userID from your server.
Once you do this, you can query the report using this dimension and date. This will give one row for each user's daily visit. Count of these rows compared to the time period, say 6 months will give you the DAU/MAU etc.
There is a setup require in Analytics Site, change in tracking code and preferably use the API or Query explorer tool to fetch the data and compute what you need.
I have made a detailed write up after finding no complete article on it: DAU/MAU Sticky users Measurements in Google Analytics
See if it helps.
Of course you can do this. In GA, just go to Audience >> Overview. Select the date range that you want. The unique visitors during this date range is listed below the chart in the box labeled "Unique Visitors".
In the Overview chart, you also select to see your data graphed hourly, daily, weekly, or monthly. On the left hand side, select "Unique Visitors" from the metric drop-down picker. That will give you your daily/weekly/monthly data.
Note that the daily unique visitors will not add up to the weekly or monthly unique visitors. If Joe visited on Tuesday and Wednesday, he will count as a unique visitor on each of those days. But he will only count once as a unique visitor for the weekly number.
My company's tool - Megalytic - lets you easily generate custom reports that can give you a lot of information about unique visitors - by country, landing page, referral source, social network, etc. You can get all this information by building custom reports in Google Analytics also, but we make it pretty and easy to share or print out as a PDF, and you can put as many custom reports on a single page as you want.
