Various flaws of other ad serving networks

Google adsense will remain the best ad serving network for a very very long time. This is a statement of fact because there are no strong rivals yet. All other ad networks are still learning and are yet to perfect their website. No wonder adsense carries its shoulders so high like a peacock. But why won’t they? When they are so efficient. When they say it, they do it. And at the stipulated time. Without delays. No plus no minus. I am yet to experience such with other ad networks. I have tried many of them but yet to find a very good substitute for adsense. Is it infolinks, adpushup, clicksor, outbrain, ayboll or dochase, adgenta, propellerads, B4psads, nuffnang or media.net? They all have one flaw or the other.
Some of the shortcomings and incompetence I have experienced in my course of using some of these ad networks include:
1. Low quality ads: B4psads, clicksor please take note.
2. Limited advertisers: Clicksor, infolinks, dochase and in fact almost all others have this challenge. Imagine, infolinks had only facebook as their advertiser for an extended period of time. Clicksor had only two advertisers for a very long time. Likewise dochase.
3. Inactive codes: This is about the most annoying aspect. No ads are displayed after placing some these ad networks codes on your site. Dochase, propellerads should do something about this as a matter of urgency.
4. Malicious codes: Placing ad codes of some of these ad networks can cause malfunctioning of your website. My sites have been blocked by Google because of malicious codes. This can cause traffic on the site to take a down turn because it would always appear as a deceptive site to users. Clicksor please take note.
5. Inefficiency: Ad network like adpushup would schedule a call with at a particular time you and fail to call.
6. Failure of clicks to convert to earnings: Dochase, infolinks please take note.
7. Disapproval of subdomain sites: Media.net would never accept a subdomain site into its network. They be aware that not all would be site owners have the capital to purchase a domain. Some prefer to start with a subdomain and eventually by a domain as the site progresses.
8. Minimum traffic requirement: some inconsiderate ad networks demand for minimum traffic before accommodating your site into their program. Some even demand for a minimum of 50,000 visitors before approval. Kudos to those ad networks that do not require minimum traffic. Outbrain please be aware.
