No. None of our service plans require logos or advertisements of any kind. You have complete control of your results page design. Register and have a look. Everything works in the demo except that we crawl only 100 pages of your site and prevent the jump from the results page to the target document. You can know all there is to know about Spiderline before you subscribe.
To remove the spiderline logo, edit the HTML in the design section of your account.
