301 from an old url. Is it the best option for a site instead of a well anchored html link or links on every page of the old site. Yahoo counts hotlinking an image as a backlink and who would have thought but I have seen this… experiment How long does a deleted link stay in the index and still contribute value… How long does Google remember old content. Links inside pdfs do they get counted as backlinks Embedded text in alt tags vs plain old text – what is better How to make video content rank. Dynamic redirects based on structure of link… (interesting) As I think of anything I will add it to the list Placement of link on page top links vs bottom links but the same level in the code – html with css putting it in another place – does googlebot parse css properly. I have thought of some in the past 3 weeks can’t remember what they are – I will stick them in as they come back to me…
