Well I've been offering my services for about 2 1/2 years now. I can post whatever amount per day but right now I'm posting about 1500 ads per day with all my clients combined. These posts range from 50 ads a day to 300 ads per day ranging from Services, For Sale and many in the Jobs. It is a tough game but its easy for me because I have my own tactics and strategies or else I wouldn't offer my services at all.
For the stickness - we do everything on our side to make sure the ads stick long as possible but their is no full proof shield that will prevent flagging. If you take a glance at the ad placements now theirs not a whole lot therefore depending on what your titles, ad content and even landing page can determine how long they stick. What I've noticed to is theirs about a sweep once or twice a week from CL in which they simply remove ads that do not belong in certain categories. All my job ad guys are doing great but for instance, I have a guy who sells GPS systems in the Boats section. His ads obviously dont' stay live for very long. Theirs about 3-5 ads per day in the cities he wants the ads posted and those are people really selling boats or portray themselves to be. His on the other hand sticks out a great deal but he still profits enough to put money back into my services. The majority of my clients have been with me about 6 months now but not every campaign will become successful but you'll definitely at least see something. Whatever you have to offer, I can give you real sound advice to let you know if your wasting your time or not. Right now, autoresponder ads are doing great, Financial Services, Ticket campaigns, mystery shopper ads and affiliate program. Any cash gifting will not work anymore unless your doing an autoresponder method.
I do use my own PVA's when posting however if you want ads in the Services, you must purchase these or provide them yourself as the rules in this section are much stricter than the others with PVA's and its a must that you have them no matter what. I use a ton of exclusive proxies with PVA's to make the ads appear more authentic to the CL bots. All the procedures are done accordingly such as IP Changes, different accounts, rotating titles. I can repeatedly use the same ad over and over without any issues however I do use a few techniques to make the ad appear different overall to the CL bots. Image ads are no issue whether they are clickable or not. A regular text ad, I have my own method of posting these and they turn out great. If you take a glance through the Jobs under Marketing/Sales/Admin Office and even customer service,the majority of those ads are mine.
