Now try to maintain quality.
You’ve got popular and finished your goals for your proxy site but now you MUST maintain the quality. Coming across VERY popular topsites, some of them are broken or hacked.
Since quality is one of the thing your visitor requires, you must maintain it otherwise, gradually you will lose visitors and one day the site will die.
This is a little rant to all those proxy topsites, web based proxy and proxy list owner to monitor your site daily. Daily, first thing you should do is check that your forms are working. If there is an error on your site, you should take down that particular page and replace it with simple offline message.
That is all for now.
the problem with most of the topsites is that they accept every submission, with the result:
dead links
spammy listings
and often cheating topsite users bring down the server by abusing the button script.
I suggest use one topsite where the user with the maximum of inbound clicks is getting the top position. Use less submissions to have clicks from your own web proxy site.
