Google unranks target keywords

[LeeAnn30]

I have read a number of changes in Google (see:http://searchengineland.com/too-much-seo-google%E2%80%99s-working-on-an-%E2%80%9Cover-optimization%E2%80%9D-penalty-for-that-115627)
But as of late I am having some problems with my website, and I am curious if anyone of you are also experiencing the same.
The problem is this in SEO it is a SOP that you use your target keyword as your anchor text having the url as the landing page for the page you want to rank for.
But recently the pages I want to rank for specific keywords are going down instead Google is ranking my homepage for keywords I don't want to rank for.
So instead of having my target pages rank it is my homepage that gets shown in Google, now this is what is really interesting the keywords I rank for are not in the meta title, description, keywords of the homepage in fact there are no specific keywords at all in the content!
I checked the backlinks and I have never created any backlinks to my site using those keywords I rank for.
And this is happening at a very fast rate, rankings and pages going down and only the homepage is showing up in Google.
I really want to know your thoughts.

That's probably just Google Bot getting smarter and incorporating Semantic more heavily than before. The link that you mentioned is most likely what you are seeing with your site as I am with couple of mine.

It's time to re-strategize.

Hello Syed,

Thanks for the kind reply, anyway does it mean that you cannot make a page rank anymore for a particular keyword? Instead it only ranks your homepage for such?

Just found this early today: More accurate detection of official pages. [launch codename “WRE”] We’ve made an adjustment to how we detect official pages to make more accurate identifications. The result is that many pages that were previously misidentified as official will no longer be. (see:http://insidesearch.blogspot.com/2012/02/search-quality-highlights-40-changes.html)

It just means Google will weigh the easily manipulated on-page and off-page factors less than they have earlier.The anchor text might have as much important as it used to before - perhaps the context of link would be more important than the anchor.  It could be a factor - not necessarily THE factor ~ I mentioned that since you wrote 'anchor text' relating to 'rankings' and now the anchor factor is not as heavily considered......

"anchor text having the url as the landing page for the page you want to rank for."
