Using submission software is a very bad mistake made by a small minority of site owners. Tempted by sales copy that promises to “Submit Your website to more than 1.2 Million Search Engines, Directories and Link pages” they pay for software that is completely unnecessary and in most cases will have a negative effect.
In practice there are only a handful of search engines that people use and all of those have robots that spider the web looking for new pages and sites. There is absolutely no need to submit your pages to these search engines because they will find you quite quickly if you have a link from at least one site that is in their index already. Of course you should have a lot more than one inbound link!
The disadvantages of using such software is that most of the sites they submit to are there only to collect your email address and then make it available to spammers. So when you purchase the software you are in effect paying to be spammed which is not a good way to spend money.
Here is a section of a page from a site that sells this kind of submission software:
Do some people really believe there are 700,000 search engines? Probably not but it doesn’t seem to stop them buying and using the software. Notice that one of the logos is DMOZ which is not a search engine but a directory. Automated DMOZ submission would be a very big mistake and all directory submission should be done by hand as outlined in a previous post Directory Links.
Some submission software claims to auto submit to guestbooks like this example here:
This is even more ludicrous than search engine submission software and should be avoided at all costs. Guestbook spamming doesn’t do anything for your site as far as the search engines are concerned, except perhaps label you as a spammer.
Guestbook spamming has become less of a problem as the number of sites with guestbooks has decreased but has now been replaced by blog spam (posting comments to blog posts that then provided a link to a spammer’s web site). Here is a section of a page from a site that sells blog link generating software:
Of course it doesn’t work because current blog software has methods of preventing blog spam such as registration and posting with captcha (an acronym for “completely automated public Turing test to tell computers and humans apart”). Captcha is used on this blog. Even if the blog spammer breaks through the barriers and manages to post their spam most blogs apply the nofollow attribute to urls in comments, so it really is a complete waste of effort.
