W3C uses several validation schemes which could make it difficult for someone to deceive search engines.
However the strict validation used by W3C could give a bonus point on Google.
Search engines are moving their focus from any single
SEO aspect. These days search engine are giving preference to websites on the basis of combination of various factors.
Although back links does constitute an important factor, but google will validate that with on-page content. If it sees that your back links contain text "adult toy games", and your 90% pages have text "charity organisation uk", then google might get little sceptical. However it is still very difficult to quantify different
SEO factors according to their respective percetages.
As per my experience i think it is as follow :-
1) Hosting + Domain (25%) : if you have country specific domains then it is helpful. Moreover your IP does matter in
seo rankings)
2) DMOZ listing (20%)- Dmoz listing can do wonder (within a specific region) if you manage to secure place under that targeted regional section.
2) Content (20%)--> further unique and good keyword density
3) Content with all niche keywords, and updation (10%)- MOst of the blogs pick up quick
PR + rankings due to content alone.
4) Relevant links from niche websites (25%)
THIS IS JUST AN APPROXIMATION
Please add your inputs. THANKS
