Next, a keyword in the visible link text and 2nd
In the actual link URL to a page, the href part. From the GRKda keyword density analyzer, Posn 1 has keyword's in the link text, but so do No's 19 & 30. No's 4 & 10 don't have keyword's in the link text.Posn 1 also has a keyword in the link, but again so do No's 19 & 30 and both 4 & 10 don't. Also on positions 10 & 19, No.10 beats 19 even though it has no keyword's in the link text or link. So far, No.10 beats No.19 even though they have almost the same keyword density. No 10 has a lower word count and no keyword's in either the link text or link compared to No 19 which has both.
So what's the missing factor/s that explain why No 19 has a lower ranking than No 10 when by the search engine optimizer rules it should be the other way around. It's nothing to do with keyword's in the title, because they all have those. What about keyword's in the Alt tags, no its' not that either, the only one that has those is No.4. I do hope you're following this so far ! Perhaps it's due to keyword's in the body content, but No.19 has more than No.10, so it's not that. Don't forget No.4 it has a lower keyword density than 10 or 19 but still manages to beat them both. The only thing in the data so far that sets No.4 apart from the others is a higher keyword count in the body content. But that's not likely to help since it also has a much higher body word count. Another analyzer used in this phase was the Search Engine Optimizer or
SEO from GR Software Keyword density in the body content  *The SEO Analyzer did not return results, so word count was calculated from the keyword density SEO did return & knowing the body content keyword count. In the Body word count, none of these pages comply with the analyzer Web Position Gold's recommended figure of 436 to 629. Now although the keyword density in the body content of No.10 is slightly higher than 19 it's also higher than No.1, but it doesn't get ranked No.1 because of it. No.4 has a lower body keyword density than all except No.30, yet it still gets ranked No.4 ! Another factor to consider is keyword prominence or how close keyword's are to the beginning of either the title, the link text or in the main page content. The analyzer Web Position Gold reported a minor keyword prominence problem with No 19 in the link text and body content and more of a problem with prominence of No.30 in the link text. But to keep these prominence reports in perspective for No 19 & 30 we must not forget that No.4 and 10 have zero keyword prominence in the link text because they don't have any link text !
