Another Look At Optimizations

We've given you many optimization tips over the years, and, as you know, it's important to consider how your ad implementations affect not only your click-through rate, but your users' and advertisers' experience as well. To support this, we'd like to remind you of the following two guidelines when optimizing your site.

1. Ads shouldn't be placed under a title or section heading in a way that implies that the ads are not ads.

For example, ads shouldn't be placed under titles such as “Dallas Business Opportunities” or “Today's Hot Deals”. Placing ads directly below titles such as these implies to your users that the links in the ads are publisher-created content. The example below shows a placement that does not follow this guideline.



2. Ads should be easily distinguishable from surrounding content.

Similarly, you should not place an ad unit by a group of links that has identical colors and line spacing. Doing so may cause users to think the ad unit is content created by you. In this situation, we recommend using a different color for the ad titles or indenting the ad unit to help distinguish the ads from your own content. This screenshot shows an implementation that does not follow this guideline:




As you can imagine, users who click on ads that they think are publisher-created content may lose trust in your site and decide not to return in the future. It's important to keep their interests in mind, as well as your own.

Also, advertisers can tell which sites have a high conversion rate for them using Placement Performance reports. A conversion occurs when a click on an ad leads directly to user behavior that the advertiser deems valuable, such as a purchase, sign-up, page view, or lead. Advertisers have the option to exclude your site from their campaigns and may do so if it is not leading to conversions.

We believe these guidelines invest in the long-term health of the relationship between AdSense publishers, AdWords advertisers, and your sites' visitors, and that they will help ensure your continued success in the AdSense program.

Testing the Network Connectivity

From now on, the '/ping' command can be used to test the network connectivity on both interfaces. You can reach any host on both connected networks from the router:

[MikroTik] ip address> /ping 10.1.1.17
10.1.1.17 pong: ttl=255 time<1 ttl="255" ttl="255" max =" 0/0.0/0"> /ping 192.168.0.1
192.168.0.1 pong: ttl=255 time<1 ttl="255" ttl="255" max =" 0/0.0/0">

The workstation and the laptop can reach (ping) the router at its local address 192.168.0.254, whereas the server can reach the router at its local address 10.1.1.12. The router's address 192.168.0.254 should be specified as the default gateway in the TCP/IP configuration of both the workstation and the laptop. Then you should be able to ping the router's address 10.1.1.12, which is on the ISP's network:

C:\>ping 10.1.1.12
Pinging 10.1.1.12 with 32 bytes of data:
Reply from 10.1.1.12: bytes=32 time<10ms ttl="255" bytes="32" ttl="255" bytes="32" ttl="255">

However, you cannot ping the workstation and laptop from the server, unless you do the following:

• Add a static route on the ISP's gateway, which specifies the host 10.1.1.12 as the gateway to network 192.168.0.0/24. Then all hosts on the ISP's network, including the server, will be able to communicate with the hosts on the LAN.
• Alternatively, specify the address 10.1.1.12 as the default gateway for the server. Then the server will forward packets with destination other than 10.1.1.0/24 to the MikroTik router.

It is required that you have some knowledge of configuring TCP/IP networks. There is a comprehensive list of IP resources compiled by Uri Raz at http://www.private.org.il/tcpip_rl.html We strongly recommend that you obtain more knowledge, if you have difficulties configuring your network setups. Next will be discussed situation with 'hiding' the private LAN 192.168.0.0/24 'behind' one address 10.1.1.12 given to you by the ISP.
