Why my PR up but SERP's down?

Today my homepage PR up to 4, and more page get PR 3, but all keyword rank down, why? my website (yzf888 dot com) had run 1 year.

Because high PR doesn't guarantee high ranking.

I've noticed that most of the links on your navigation bar (on the homepage) are simply pointing to the same page. You should correct this to make your site more usable. Then you have the links page... well, you probably received link juice from your reciprocals early on but now they're maybe being discounted by Google for what they are. Not sure about this though.

I know high PR doesn't guarantee high ranking. But today homepage PR from 3 up to 4, 20+ keywords that I optimized from 10-20 down to 400+, I lost all traffics from google.

But yesterday more page PR up, and at same day, my 30+ keywords that I optimized from 4-20 down to 400+, I lost all traffics from google. I found some keywords in new page down to 400+, then back to 4-20 in one week. But keywords in all site pages (new or old) down to 400+. Is my site enter sandbox ? How get out it ?

coincidence.... They are not related..

I don't do reviews - but here's a prossibility [likely a PROBABILITY]

The fact you watch PageRank and note that as a requirement for improvement suggests you likely see value in gaining a link from a domain as a sitewide value [e.g. a footer link or a navbar link that's on an include file so you get a link on every page.

Google is killing off the value offered from these... but because PageRank is calculated separately [like this weekend] but is past tense calculation [as in it updated today but that was actually the PageRank from as far back as months ago.

If nothing else changes I'd say next PageRank update you will find yourself lower than now and possibly less than previously...

e.g. If you were a PR3, and now a PR4 - I say PR2, PR1 or PR0 is your future... all other thing being equal and unchanging.

I found my all keywords SERP's down at google update day. I think google put my site into sandbox, but google up my PR to comfort my break heart.

Hi Fathom,

I have noted you have made this very point in the past and indeed what you are saying is happeing to me. What I cant figure out is why pr4 will become pr3,2,1,0 if nothing changes ?

Why do I feel like someone stole the family jewels.

Also if PR is a useless nonsense why does the question creep up at every update, why does pr exists and why is there a forum board all about it. I cant get my head around the existence of something and peoples fascination with it if it means nothing.

For google IMO it exists primarily as an incentive to get people to install the toolbar. This toolbar gives google a wealth of user behavior data. The second advantage it gives to google is it reduces spam by discouriging link trading.

For the individual it is of interest and is discussed because its from google and it changes....

For you point If nothing changes ..... This is the internet in the last 3/4 months since the last TBPR update much has changed. There would be billions more sites/pages now to share PR around. It should in theory get harder to keep any page rank as the total amount of sites/pages on the net increases. This is not suprissing.

Don't loose focus on important things for unimportant distractions IMO.....

So do you think that you have, at least in part, answered your own question?

It is very true that PR and SERPs are not a direct correlation and have very little relativity.

So on that basis, I think you are asking the wrong question and looking in the wrong area. There will be a reason for a drop in SERPs, there always is but here you have ruled out one possibility.

It could be one of the following reasons, but you need to provide more information

1) A Change in algorithm (quite possible)
2) A penalty of some sort - due to a linking tactic or duplicate content
3) A badly performing server
4) A site error
5) You are seeing results form a different data center the previously

Check Google Web Master Tools, Google Analytics and your server logs for clues as to why this may be.

1. PageRank always depreciates

2. If you lose links it's natural to lose PageRank, but the actual effect of links to ranks can occur near immediately where the visual change on PageRank may actually be seen for the first time months later.

3. PageRank isn't useless... it's just not useful for what people wish it to be useful for... e.g. many people view links from high PageRank pages will enhance their ranks - that mostly false... the gas guage on your car doesn't actually allow you to go from point A to point B - does it? PageRank is a guage.

What it's useful for is crawl rate to credit... A high PageRank page will allow you to get credited for a link faster than a lower PageRank page... because the page gets crawl more often... BUT just because you get credited faster doesn't mean you got better credits... that where the anchor, page topic, anchors to that page, those topics, and anchors to those pages affect the credit value.

I think i added more pages to optimize some keywords for 20 days, but only 1 or 2 inner link to the new pages. So i got penalty of google. I decide to add inner link to the new pages from every pages on navigation bar.
Please help me more advise.
