I am just fixing a website that used to rank not too bad, had some pagse bringing 3-5$ a day, then disappear from the chart, I found that each page had 4 links to the home page, 3 with the exact keyword that is also the name and the domain of the site, redwidget.com, name red widget, and one link in the footer was redwidget.com link, so I removed all this linking, except one in the sidebar, if people want to go back to the home page, so they were 120 links from internal pages, all pointing to the home page, plus I removed the name of the website red widgets from the title.
Lets see, what will bring, I did less than 12 hours ago, I see some moves but I am not sure, will wait and see other 24-48 hours.
Plus most of the pages have still high keyword density, will write another paragraph each and add after I have an idea if the first fix worked. and see if I can improve more.
Thinks how much money we lost, not doing this small fine tuning, I had a page ranking for a keyword, that used to move between 5 and 11,before disappearing for some google update, when was in 5th position use to bring 10$, when went on 2 page 1$ or almost nothing, may be ranked for others keyword too. Anyway think if that same page would be stable in 1st or 2nd, or even always in 5th. On a 30 day period is good money, in a year is a lot, fix in 5th would bring about 3.500$ a year from a page monetized with Adsense, not bad, may be took me 1 or 2 hour to write that article.
I feel stupid to dont have looked into this stuff that phpbuilt show us.
