Interesting! I believe, when I tested Bodis example domains, I had JavaScript set to “Ask to activate”, which could be one of, or THE reason why even with ad blockers disabled, I was redirected to various online retail stores i.e. dell.com, mlbshop.com, realtor.com, fanatics.com, etc.
Redirecting a visitor who disabled javascript is a simple process, even though my post above is not related to it. I know how to do it. Parking services should already know and implement it. You can't show ads to a visitor with disabled javascript -unless it's a text ad-, you can only redirect it. However, monetizing traffic without javascript is almost impossible especially if adblocker is enabled (adblocker + disabled javascript) for 2 or more reasons:
1- Ecommerce sites don't work without javascript. Their style will be broken (the page will be collapsed or vital elements -such as product image/price- will not be displayed) or checkout/cart systems will not work without javascript.
2- Adblockers can block redirection to most ecommerce sites, especially if the redirected URL has affiliate or tracking code. Adblockers can recognize those. I successfully redirected javascript disabled visitors on 2-3 of my domains with very high javascript disabled traffic to other domains/websites of my own. I was able, because my domains were not popular ecommerce sites which were blacklisted by adblockers. Of course, if you don't have access to server logs or if you don't use statistics providers like statcounter or piwik (analytics alternatives), you can't notice that traffic.
I believe more than 60% of visitors have adblockers installed. Most of those visits are hidden on traffic stats as well. Adblockers don't only block ads, block also traffic statistics. So, if a domain receives 100 visits per day while parking, you can add 200 hidden visits to the 100 with no adblocker, the total is likely 300 per day. It's possible to monetize that 200 visits especially if you have your own products to sell as adblockers hide mostly javascript codes of popular ad networks and statistics.
It's less likely to receive offers from parked domains. In other words, if you don't park, you can receive more offers. When you disable javascript you can be redirected or see blank page. I tested on parkingcrew, the page was blank. Perhaps I could be redirected. The same page displays the offer link even if adblockers enabled. But when I disable javascript the page shows nothing. This means the content is displayed by javascript, so is subject to be blocked by adblockers in the future. Remember, anything that is javascript can be blocked by adblockers.If it has not been blocked yet, it has not been added to their blacklist. So it's just a question of time and when it happens you may notice immediately. Also there are variety of adblockers and filter lists (blacklists) around.
If selling domain is more profitable than parking revenue, I would set up a landing page and forget about parking revenue completely or you can monetize your domains with your own ad codes if the traffic is good -even if the domain has not much real content- while you can surely receive offers with no doubt. Of course you should not use adsense on the domain with no real content. But adsense is not the only one ad network.
After reading this thread, I decided to offer low cost, unblockable, seo optimized, fast loading custom landing pages on the services section of this forum. I can help on monetizing the traffic as well or you can search "adsense alternatives" to learn other traffic monetization options. I can add the ad codes of your favorite ad networks to your landing pages. But I don't recommend placing ads if selling the domain is more important. Because displaying ads will not only lower number of offers but also will not generate good revenue if adsense is not possible due to lack of content or domain history (domains that were banned by adsense in the past) or domain itself (domain may breach the very strict adsense TOS by default, may have blacklisted words like p0rn).
So monetizing a domain without much traffic (e.g. 300+ visits per day) and much content (e.g. 10+ pages with minimum 500 words per page) is not worth to lose a possible offer, unless the domain is 15+ years old and/or with some quality baclinks. I am webmaster, developed some domains before that were worth. But most domains, like 99.99% or less, (9,999 out of 10k) are not worth to develop, I know about ad networks what I write above, because I am webmaster and partially domain developer for the last 15 years.
