First, there is no need to start a new THREAD when you have a question related to a thread already started - just press the REPLY button.- - like I have done just now to get here.
You ask what is a link page.
Its a page or area on your website that shows the web sites of other businesses that people can visit direct from you web page - its links direct to the other site.
Click on my website at the bottom of this post and then click on the tab at the top LINKS and you will see a list of web sites, all but one are related to carpet cleners in other areas of the country.
Apparantly have related links is good for your web site rating but thats too much for me!
