I've created the following scale to help give some feel of what "a lot" might mean. It uses estimates of unique monthly visitors for popular websites to create a high point, then works down from there. The "what's a lot of traffic?" scale (monthly uniques): "A right royal load" = 1 billion+ e.g. Google "A mother load" = 500 million+ e.g. ...

I've just broken down Nicks answer for <100,000 uniques as I think it needs expanding a bit :) 50,000 unique monthly visitors (a pop) A healthy amount of visitors and showing the signs of value 25,000 unique monthly visitors (a buzz) Healthy interest 10,000 unique monthly visitors (a fizz) Signs of potential for small sites 2,500 unique monthly ...

Funny this should come up, I was dealing with a similar problem at work today! @HeatherWalters has covered most of the good stuff, but there are a couple of things to add. You can block referers by domain using the following htaccess code:- RewriteEngine on # Options +FollowSymlinks RewriteCond %{HTTP_REFERER} spammer-one\.com [NC,OR] RewriteCond ...

Massive sites like Google, Facebook and Twitter don't necessarily get the 'best' servers in that they don't run a small number of high-powered servers, they run a massive number of smaller and cheaper servers. They expect hardware to die and be replaced and the code allows for that. Some things that are typical in massive scale sites: They don't use SQL ...

Optimise your application before optimising your server infrastructure It's tempting to throw more servers at traffic spikes or overpay for resources that you may never use "just in case". A better solution is to optimise your application to withstand spikes before they arrive. Specifically: Cache dynamic code Your application should serve static html files ...

Have you considered the possibility that they are visiting your site, hoping you will research who they are, by following the link (so that you end up visiting their spammy sites.........the blackest of blackhat SEO)? Have you accessed this information on website hits purely through GA or have you looked at your website's traffic logs? Maybe they aren't ...

The "how much money you can make out with Adsense" could be another scale, even if IMHO the revenue estimates provided in the above link are extremely optimistic! I usually see much, much, much less money per month compared to the revenue estimate values given out in the above link, I would say to divide these values by 1000 to get maybe closes to the ...

You're probably seeing bots of some sort. They're very common online, used by everyone from large search engines (good) to e-mail spammers (bad). Just make sure they don't recognize things like e-mail addresses that don't help your SEO anyway, and it should be fine.

Thought I'd mention HipHop for PHP, which turns PHP into C++ and was developed by Facebook. Facebook did some work on APC as well I believe.

This really depends heavily on how your frontend servers distribute load. If it's not designed to have extra capacity added to it at the flip of a switch (or maybe better yet, automatically when a sustained spike is detected), then planning for this sort of thing is tough. If you design your load balancing in such a way that you can flip on extra servers in ...

You're going to need more details than just the number of concurrent users. What web services do you need (PHP, ASP, static files, database, which database, cache layer, etc...)? Some of this will What level of redundancy/availability do you want? Higher availability means less potential down time but at an expense of higher cost, time, and skill to ...

How your server will be set up depends a lot on what language your using. You should decide between PHP and Ruby then ask about a good setup for whichever you choose. Whichever one you choose, make sure you use good coding techniques. Having sloppy code can cause more issues than just performance. If you use PHP (which i would recommend), read up on OOP in ...

I've been trying to track this one down as well. Whatever they're doing, they seem to rotate domains every couple of weeks to a month. This can easily be seen in our analytics by filtering by traffic from Bangladesh (which we get very little legitimate traffic from.) In our case, the traffic isn't affecting sales but is a couple of orders of magnitude ...

I have seen a coding problem that can cause extra page "views". We had an empty image tag on a page that looked like this: <img src=""> Because we had a base href on the pages, that caused Internet Explorer to fetch the home page instead and try to load it as an image. Other browsers seemed to ignore the tag. It would help to know how you are ...

Have you checked your access log / webstats? Is this reporting a higher number of visitors to match the bandwidth usage? Are you getting an increased amount of bot traffic? Rogue bots can perhaps be blocked in .htaccess if this is an issue. Are your images optimised? Have you enabled gzip compression for your pages? This can drastically cut the size (and ...

You saw a huge increase, but "no significant findings"? Is the traffic still coming from the same general geolocation? Is there an increase to another geolocation; if so that possibly indicates spambots trying to seek out forms to spam and the sort. It sounds like you're going to have to dump traffic between say a coouple of months before the holiday ...

I think it depends. If you have a niche website with 10,000 monthly visitors, this could be a lot of traffic, too.
