Does reverse proxy create a slower page speed and navigation?

I think you're not fully embracing the lean startup methodology. Is your SaaS handling some operations that are a matter of life and death or critical mission thing for an organization? if the answer is No start with simplest option and do a soft launch and invite some carefully selected (50) beta testers. Get the service going and gather feedback as much as possible. Then when you're at version 1.5 or 2.0 you'd know the problem you're solving a lot better. Slavi, Orbisius & qSandbox

Try these actions if your touchpad stops functioning:- Make sure the touchpad is clean and free of debris. Numerous times, press the Esc key. Ten seconds of drumming using your fingertips on the touchpad. Turn off, then on again your Chromebook. Execute a hard reset. If your Chromebook has more than one account, delete the one that is causing touchpad issues before adding it again.

I personally have had success with the Google Keyword Finder. This is part of the Google Adwords program for estimating keyword traffic and since Google has statistics on everyone's surfing and search habits, this is your best bet. My advice to you is that before you try estimating server traffic for your marketplace, select 5 to 10 short and long tail keywords that you want to target and then use Google's Keyword Finder to look at the search traffic. I hope this helps. Bruce

Book arbitrage can be a great way to make extra income with Amazon FBA but it's not for everybody. While I don't have specific experience with the program you posted, I looked at the web page to see what they are all about. First, the link opened 10 identical browser tabs which is pretty suspect and feels spammy. Their program is specifically geared to finding cheap books on Amazon that have few or no FBA sellers. You buy the books and relist them as an FBA seller at a higher price then pocket the difference. I don't have any experience with this type of arbitrage so I can't say if it's a profitable method. If you're just starting out, I would go to places like library book sales and Goodwill to find cheap books. There is a big movement right now for college students to find alternative sources for textbooks since they can be extremely expensive. This is an excellent opportunity to find cheap textbooks locally and sell them on Amazon. You make money and the buyer saves money vs. buying from a bookstore. If you're considering buying this program, I would strongly recommend doing more research as there is a wealth of free information out there on book arbitrage.

In my mind, private label and building your own brand/nich products is the way to scale on Amazon.
