INVISIBLE TABLE CELLS
Similar to hidden div tags you can hide contents and links inside a hidden table tag. You can display the content of the tables to the search engines with stuffed keywords and links but the users will not be able to see it. We can actually make the table size bigger than the original width of the page like 150% or something so the extra 50% is not displayed to the users only the search engines can see the extra 50%. This gives the spammer option to stuff spam keyword rich contents which is literally hidden from the users. It's difficult for the search engines to detect this sort of stuff.
The combined powers of CSS and html and the loose dtd allow the unscrupulous site owner to hide the content of table cells loaded with keywords and heading tags.
CSS permits the flexible positioning of Web page elements; it's a flexible coding language that search engines do not fully understand at present. In short, the search engine doesn't really know what's being displayed. This trickery can be specified in a separate CSS sheet (.css file), which a search engine may or may not index. This CSS style sheet file, however, does affect the display of content on the page.
In this example, the CSS affects the display of the body of the Web page, which is set to 97%: {Font-family: Arial, Helvetica, sans-serif; width: 97%; font-size: 10pt; overflow: hidden; color: #000000; margin: 0px ;}. Within the regular code, .gif files can be placed in the page at a width of 150%, ensuring that part of the page is not seen. That extra 50% provides plenty of room for keywords stuffed into "h1" tags.
