Text link advertising economics

In recent years, as the number of pages on the internet has increased,  PPC advertising revenues for many websites have decreased substantially
Text Link advertising can be a source of some revenue, but only for those who have worked with the different ad networks.
With Backlinks.com, if your website is PR0 or deindexed, it is deleted from their inventory.A text link on a PR1 or PR2 website pays $0.5 or $1 / month but there is no guarantee that even a single text link will be sold on a particular website in a year.
Other text link ad networks like Linkworth.com, TNX.net have different screening criteria,and there is a lot of unsold inventory. Selling advertising directly is also an option to be explored and is the best long term solution.

However, the webmaster expenses like domain registration/renewal fees (approx. $9/year) are fixed.
Web hosting costs per website depend on web hosting optimization skills.

For PPC advertising from networks like Infolinks, the Infolinks logo is clearly displayed on the ads, so the network takes responsibility for the ads displayed, but for text link advertising, the ad network is invisible to the visitor to the website.

If a webmaster believes that false rumours are being spread by the ad network (they have managed to convince powerful people by fabricating lies ) or there is a lot of uncertainty (the domains/websites may be transferred or forcibly sold to someone else), it is best to let most of the domains expire and wait till conditions improve. The monthly revenue decreases , but so do the considerable domain renewal fees paid to the registrar and registry.

In another post, we will provide proof with screenshots of how Inforum.in admin , moderators and users go all out to protect the identity of a person who makes false accusations. In other industries, proof is important, especially for a financial transaction, why is it not the case for websites?
