# How to add domains

Buy Pro license
Add an A-record to your domain’s DNS:

@ A x.x.x.x where x.x.x.x is your server’s IP.

# Why doesn't the stream work, or why does the click go to a wrong stream?

Go to the “Maintenance > Logs > Traffic” page.
Enable traffic log.
Make a click, or wait until a click gets into a wrong stream.
Look at a traffic log. There you'll be able see how the sream filters have just functioned.

Also, have a look at the “Additional > Traffic Simulation” menu. You can emulate getting any user to a campaign there.

# How to find out the reasons for traffic loss

Compare the number of “raw” clicks (heats), not the unique ones. Keitaro uses its own algorithms for uniqueness.
Compare the stats in the same time zone with the affiliate network.
Check your domain’s SSL-certificate.
(ONLY for the trackers installed via the terminal). Go to Maintenance > Status and check the max children reached. If the value is more than 10, write to our support team, we will help you to set up PHP-FPM.
In case you use shared hosting or a server with ISPmanager – reinstall the tracker using our current solution for servers How to Install Keitaro.
Check your scripts work in AdBlock.
A lot of bot can stuck in the redirects such as meta-redirect or double meta-redirect. Keitaro could not mark them as bots, but some bots can’t go through these types of redirects. To check this, make a redirect to another campaign and see the difference.
Check all the streams, make sure all destinations work.
Check Maintenance > Logs > System Log for errors.
If you use CloudFlare, switch Firewall to “essentially off”. Disable the compression.
Validate your domains with host-tracker.com, http://urlvoid.com and http://virustotal.com.
In case Keitaro is integrated with Script or Iframe, the traffic loss could happen because bots or browsers with high level security settings are visiting the page.
Check your log-file access.log from nginx with server requests. Check if there are 500 or 502 errors, e.g.: 84.154.60.91 - - [16/Nov/2017:03:36:01 +0200] "GET /cmp HTTP/1.1" 502 1243 "http://test.com. 502 means your server doesn’t cope with the traffic, 500 means the errors in tracker’s work (see Maintenance > Logs).

If the website is the source of traffic:

Check if the domain is present in antivirus databases through virustotal.com;
Check if there are problems in Keitaro functionality, check the logs /var/log/errors.log и keitaro_errors.log;

If the website is the traffic receiver:

Compare hits, uniques are counted differently in different systems. If the server statistics, for example, WebStat is installed, check their indices.
Keitaro can skip the bots if those do not load the counters;
Counters may be blocked by browser plugins.

# Why does FB and Keitaro stats differ?

Possible reasons:

Your ads are visited by spy services like AdMobiSpy;
You compare the stats in different time zones or for different periods.
Facebook doesn’t calculate repeated clicks, check unique clicks.
Disable Prefetch settings (Maintenance > Settings).
You are using an old klick_client.php library or WP plugin.

# Why is the domain with Keitaro marked as "Malicious site"?

To avoid it:

Create a file main.html with any content in the domain directory;
Open the page “Maintenance > Settings > Misc > Domain Action”;
Choose action “Redirect to URL” and write URL of the created file.
