If you tweak your site to perform better in search rankings then you practice science of Search Engine Optimization (SEO). It's possible to start using PHP scripts on your site without losing that high ranking of yours.

You've probably noticed your site rise and fall in search engine rankings quite a bit. That's just how it goes since search engines such as Google like to change their algorithms around.

If one day you decide to rename all files on your site you can be sure your Google listing will moved off page 1 of your target search keyword onto back-listings of page 67 and beyond.

When you rename a file on your site, and another site links to that file, anyone coming to your site thru that particular link will get an error. When a search engine crawler sees this, it decides your site and decides either to lower your ranking or delete URL from its search results entirely.

Search engines don't want to send their visitors to Not-Found pages... makes sense, doesn't it?

Okay, so let's say you don't want to have a ton of broken links across your site, which will cause you to drop in search results, but you want to tinker with PHP a little bit.

There's an easy fix for that. You can actually name your PHP scripts so that they end in .htm or .html, and have them run as PHP scripts on your web server. So from outside world it'll look as if your site is full of "updated-by-hand" content.

All you have to do is add this line to your .htaccess file:

AddType application/x-httpd-php .html .htm

Adware is a software program that you install on your computer that displays advertisements while program is running, either as a banner within program or as a popup. This can be a good thing. It helps keep program free or low-cost for end user.

If program displays random advertisements without gathering information about your online activities, then it's considered safe or ethical. You'll see same advertisements that every user of program is seeing. And program isn't gathering information about your surfing.

Why Should You Have to Put up With Ads?

I don't have a problem with advertisements on Internet or even ads within free or low cost programs. This, in my opinion, is no different than an ad on television or in a newspaper. It's what keeps these things low cost and keeps businesses in business.

Advertising has a purpose. It tells us about a company's product. I can think of a lot of great products I've bought that I would've never even known about if it wasn't for advertising.

I do have issues with some tactics that are used. For instance, adware programs that bury deep within their EULA statement (End User License Agreement) fact that they collect information about what you're doing while you're online.

Most computer users don't read EULA, especially if it's long and full of legalese. We should read them, but fact is, we usually don't. Or we quickly scan them until our eyes glaze over.

The advertisers may have what they consider valid reasons for gathering information about your surfing activities. Usually it's stated that they want to display ads in which user would most likely have an interest.

From an advertisers point of view, that's probably a pretty good idea. But that should be your decision whether you want them to profile you or not.
