Welcome to WebmasterWorld Guest from 188.8.131.52
I could not understand why the traffic had dropped so drastically on my middle site...checking stats not site.
Then after 3 days of worry and belaboring the adsense stats I visited my own site (heh, instead of WW) and the index page wouldn't load! Bottom bar said done but nothing was there. No 404 as the poor thing thought itself loaded.
Anyway, I quick opened it up for edit and found some minor changes I had made over the weekend that had somehow resulted in a major mess up of my header tags.....teach me to take that extra moment to recheck the pages I 'fix'.
Anyone else like to share how they bit themselves in the, ahem, foot regarding loss of adsense revenue due to their own 'dumb webmaster mistakes'?
1. So, I puttedd the templates for a medical website on a travel site.... can you imagine that?
2. I created a "catch all" email adress. It worked pretty fine to get all the emails sent to the wrong address... Until somebody (maybe my competitor) found out... and started sending emails to tons of people from "whatever[at]mynameweb"... FIRST, everybody received spam, second, I received lots of replies and "mail delivery" errors, coming back to my email. So, after the weekend, I got 500 emails and my account suspended.
Too bad hu?
My dumb AdSense mistake was putting it on a site for scale model cars. Despite using the special AdSense tags telling it what to ignore and what to concentrate on I mostly got ads for a different type of model. The human kind. I didn't think AdSense even allowed that type of ad. My members certainly didn't appreciate those ads. After several months of complaints and virtually no income I dropped AdSense.
I had a similar experience last year. My website is all about tech stuff. Now, my wife and I were going on a cruise, and one of the stops was Honduras. There's a children's orphanage there, and I decided to make a post on my site's front page about how visitors could donate. See, there's some weird rules about being able to receive a lot of mail there, I think they have to start paying for it after a bit (so you might pay to ship it out, they may have to pay again to receive it). People coming by plane have weight and size restrictions on their luggage, but on a cruise ship as long as it can fit in your cabin you can bring as much stuff as you want (and if they're really nice, will let you store that stuff elsewhere). So, I got quite a few PayPal donations which I used to buy supplies, mainly at Sam's Club. Met a guy in Florida who donated a lot of supplies. Got on the ship, made sure it got to the orphanage, and everything was great.
Fast forward a bit, I dunno, maybe a month or two. I have ads blocked on my site, but occasionally check them out. I notice there's a ton of ads about sperm banks, egg donors, and everything relating to that! I go through, find the urls of each one, put them on the block list, but more keep popping up! It takes several days for me to realize that google is seeing the word "donate" and thinks my site must be about people wanting to donate sperm? Ewwww! I reword everything, tell google to ignore the entire block of text relating to our trip, and eventually the ads disappear.
She clicked on the ads over 10 times (she was interested in the subject though).
I got banned by Google for her actions, but than got reinstated on appeal thankfully.
Learnt my lesson and never tell friends, coworkers, family ets... about my website (especially since all my coworkers share the same IP as myself).
If you are using a database driven site, not checking the integrity of your backups regularly and of your backup software.
I was happily about to add about 200 new pages to my site uploading them with phpMyAdmin and, whoah! corrupted. Then, about to recover from backup copies. Whoah, corrupted! Then in panic, I ended by screwing the local copy.
Everything corrupted. Last sound copy was from middle August.
Now, I am in my way to restore content since August scavenging uncomplete sql files, Google's cache (thanks, thanks, thanks...) and rewriting some of the lost content (not 'very' much).
Oh, and besides, I am changing the way I make my backups (never using phpMyAdmin for that again) and I am about to buy an external 80 Gb drive to make regular images of my hard drives.
As some one said: "The powerful weed of knowledge is harvested in the dull and sour fields of experience" :(
PS. And all this when I was making my tiny way up with Adsense...
Otherwise, simply not tracking what we're doing with adsense and ending up going with a sub-maximal adsense setup instead of something better.
I wish I had more to offer, but that seems to take the cake
One of my biggest mistakes have been not using my link checker after major changes. I have gone in an changed the link to the contact form before and forgot a " in the tag. Went so far as to update the sitemap, and resubmit to google, then later browsing the site saw the error... Caused google to ignore 100+ pages...
Slowly it is coming back, thank God is was not my main money maker site...
I essentially shut myself down for 4+ days because I was in too big of a hurry to doublecheck my typing.
Sure made customer support easy for a while though. No websites - No customers - No support.
My worst and most embarrasing was I'd been making notes about what I planned to do for promotion, including listing what competitors had done (both good and bad.. with some rather harsh comments) and many personal notes included.
Somehow I accidently overwrote an inner folders index page with those notes.. didn't notice for days... others did though. Was up long enough to be cached by Google. :(
Moral of the story.. always, always, ALWAYS triple check any changes after upload... with a clean cache.

When Google first started I found My site in their engine, thought about being listed in such a loser with such a lousy name that I became incensed. Fired off an email to them to tell them I did not want their listing and remove me immediately! (forgive me please Mr. Google).
Well thank God they ignored that "crazy woman's" email and deleted it....whew.,.,.,.
My biggest blunder was leaving a BODY tag off a page AND making a relational link ../ when it should have been ./
Funny the browser was forgiving of this, but my link checker alerted me to the problem. It caused one of my minor sites to get dropped by G. It is back in now :) but it was a hard problem to find!
