Update: Backlink Analyzer is free link analysis software which has probably the best feature set of any of the link analysis software products on the market.

The Original Link Analysis Software
When OptiLink ($224) came out a few years ago it was a software product like no others. A few weeks ago the second version of PageRank Prowler ($97) was released. PageRank Prowler is a product similar to OptiLink (which only lacks the link text features).

Dirt Cheap PageRank Software
Now I haven't tried the full version of it yet, but recently software by the name of PageRank Digger that only costs $39.99 via PayPal was released. I guess it's claim to fame is speed. "You will be able to scan over 2000 domain names per minute." It is not just scanning links and getting PageRank that matters though. Being able quickly evaluate and rearrange the raw data is what makes it really useful. I think this tool is targeted more toward the expired domain community vice the seo community.

Branding & Creating Better Products
It is amazing to see how quickly advanced link tools (or any technology) can become commodities. I wonder when someone will be smart enough to market a link product which is BETTER vice cheaper. I can think of a few upgrades that would make the best link software way better and am surprised that nobody has marketed them yet. I wish I had more time to learn programming... :)

Example Link Analysis Software Upgrade
I am surprised there is no specific parameter link analysis software on the market. Software which scans Yahoo! or Google for .edu links which link to your competitors. That is just one example of a useful modification I don't think has been marketed yet. I got a couple other ideas too...email me if you are a programmer who wants to make really cool link analysis software.

Do you know of any link software which better than OptiLink? What on your site makes it better, vice cheaper? The competitive nature of the web will eat up most people who use cheap as a sales angle. Branding is where it's at.

Recently Shawn Pringle launched PR and link analysis software by the name of PR Prowler. The first edition was a bit bulky and slow, but recently he launched PR Prowler V2.0 which has many needed upgrades.

PR Prowler operates in its own browser window similar to OptiLink. OptiLink still has a few more features (such as showing link text), but PR Prowler allows you to search for backlinks and keywords as well.

When you use PR Prowler with the Google link:www.evilcompetitor.com function it will return their backlinks and allow you to manipulate them in multiple ways. PR Prowler allows you to organize the links by site or PageRank or by how much the link should boost your PageRank (estimated). The best part about PR Prowler is that it primarily operates in the background so that you can do other business while it is collecting data.

Any software which runs in the background, checks backlings to the full Google database search depth (1,000), and will sort the results by PageRank is easily worth well over $100 to most webmasters, but PR Prowler only costs $97. View the official PR Prowler website.

Why use the Meta Refresh Tag?

Many people use meta refresh tags to tell the search engines that their pages moved. It is not the most elequent way to do so though.

What does the Meta Refresh Tag Look like?
Place
<meta HTTP-EQUIV="refresh" CONTENT="0;URL=http://www.redirectsite.com/">
in the head of your page copy. The number is a measure of time to redirect the browser to the new location (I believe in milliseconds.)

What is the problem with using a Meta Refresh Tag?

One of the bigger problems with this is that it is a common spam technique. Some people suggest setting the meta refresh to at least 5 seconds to avoid any ranking penalty.

In addition Google will show the URL of the original page in the search results if it has a higher PageRank than the location of the destination page. Last month they discussed Google's problems with the meta-refresh tag at WMW.

What is a 301 Redirect?
A 301 redirect is a perminant change of location code. It tells a search engine spider that a page or website has moved.

What does a 301 Redirect look like?

Redirect permanent / http://www.newurl.com/cool/

The 301 redirect code goes inside a .htaccess file either at the root level or in a local level. You can also use a 301 redirect to move just a single page.

Redirect permanent /oldpage.htm http://www.newurl.com/cool/

Other 301 redirect info
Yahoo! Slurp has been having trouble resolving 301 redirects for a while now, but when they work correctly they garner no penalty and all the link popularity is parsed through to the new location.

uptimebot.com (not linked due to excessive questionable ads) - provides uptime info and server info from different configurations as it spiders the web. also will email an inbound link report every day if you wish.

http://www.recip-links.com/ - allows you to enter a list of up to 50 reciprical link locations to see if those link partners are still linking to you.

http://www.dead-links.com/ - searches your outbound links for dead links. (similar to what Xenu link sluth does, but does not require a download)

http://www.linkcounter.com/ - measures the inbound and outbound traffic for your site for a meager fee.

Many articles have came out recently stating that reciprocal link exchanges are a waste of time. This is true if you can afford to spend a bunch on links, but if you are a bootstrapper you will need to do all the little things. Reciprocal link exchanges can still help boost link popularity some.
Shawn over at Digital Point creates some of the best free SEO tools on the market. Recently he whipped up this free reciprocal link checking script, which reads a file of link partners (in the same directory) by the name of sites.txt. sites.txt is a list of URLs to check (separated by a carriage return).

<?php

$mydomain = "www.yourdomain.com"; // Set this to your domain

$list = file_get_contents("sites.txt");
$urls = explode ("\n", $list);

echo "<B>Checking back links to $mydomain....</B><P><FONT SIZE=-1>";

foreach ($urls as $url) {
if (strlen ($url)) {
echo $url . "<B><FONT COLOR=";
if (strpos (file_get_contents($url), $mydomain) != FALSE) {
echo "GREEN> Found";
} else {
echo "RED> Missing";
}
echo "</FONT></B><BR>";
}
}
echo "</FONT>";

?>

There is an ongoing discussion about his free reciprocal link checking script over at the Digital Point forums.
