What could cause a drop in pagerank
-
Our home page pagerank dropped from 4 to 3.
nlpca(dot)com
What are the possible things that could cause this?

Vahe,
I accidentally clicked 'Good Answer' twice for EGOL
Your answer was informative. I will be sure and get you next time.
-
"page rank" updates can be a cause - http://www.seroundtable.com/google-pagerank-update-14684.html
I wouldn't stress too much importance on PR.
Hope this helps,
Vahe

I recently was adding 4 keyword phrases per title (and one or 2 per URL) to many of the internal pages of nlpca(dot)com. Some of the keywords were a little off topic, but most were OK. Before I could continue and add the same keywords to the H1 and content, we got dropped from a 4 to a 3 in pagerank and we slipped 20 positions for our main keyword 'NLP' and others as well.
I very much doubt that this would cause a drop in pagerank. Pagerank problems are usually associated with link manipulation.
You say that you were adding off topic keywords to page titles. I believe that google imght consider that a small sin. I've never heard of google reducing pagerank for something like that but you never know what google will do and not tell people about it - but a visible pagerank drop is a warning.
Did you get any messages in webmaster tools?
Using off-topic title tags is a cousin to cloaking. It conveys to searchers that you have that off-topic content on your page and then when they arrive and you don't have it they are not happy. They feel like they have been spammed. Google might detect this by bounce rate or some form of report from searchers. They might also detect it from during a automated review of your content.
One experience that I had was with a group of about 80 pages. I published them to see where they ranked then edited all of the title tags, see where they rank, edited the title tags and see where they rank, and then did it again. Those 80 pages all took a big hit. They stayed down for about a year before recovering their original rankings - which were quite good.
That's all I can say. Lots of the above is not "hard evidence". Just what looks to me like cause and effect and guesses at what google might do.

As per EGOL, it is both. Another thing with the changes you are making to the pages, if you change things to the point that the meta desc. does not match the content, you will cause a higher bounce rate because when someone clicks, sees something other than what they thought they would see, they leave. That will also affect PR (IMO).
EGOL nails a lot here.

Thanks again for your always excellent information EGOL
Let's talk about this one:
-- doing something naughty that makes google drop your pagerank as a warning or as a punishment
I recently was adding 4 keyword phrases per title (and one or 2 per URL) to many of the internal pages of nlpca(dot)com. Some of the keywords were a little off topic, but most were OK. Before I could continue and add the same keywords to the H1 and content, we got dropped from a 4 to a 3 in pagerank and we slipped 20 positions for our main keyword 'NLP' and others as well.
I'm trying to determine if Google dinged us for this, or if it was something else, and if we will come back up - it's all fixed - I'm using one or 2 appropriate keywords per page except for the home page, and I've added appropriate H1 and content (3 times per keyword phrase)
But we're not going back up.
Looking for some of your brilliant advice EGOL

Several things can cause a drop in page rank of the homepage
-- loss of links to the homepage or any part of the site
-- important sites that link to you loose some of their links and thus have less pagerank to pass on to you
-- changes in the links that important sites have up to you - changing the code so that they do not pass pagerank - these could be connections through a script
-- changes in the linkage structure of your site that change the flow of pagerank through it
-- periodically google recalibrates pagerank (If they didn't tons of sites would be making it to ten. This is a math adjustment similar to adjusting for inflation. If your site gains PR at a lower rate than the web average your pagerank could go down
-- adding a ton of pages to your site could cause a drop in pagerank as pagerank flows out of your main site and into those pages - similar to adding a new wing onto a swimming pool and then connecting them to allow water to flow in
-- (some people will disagree with this one -- adding a lot of links to your site that connect to other websites
-- doing something naughty that makes google drop your pagerank as a warning or as a punishment
-- if your site just recently earned four, maybe it was a very low four, now your site is showing as a very high three, this could just be flux in the calculations and rounding... keep earning links and four will return soon

Is pagerank on-site or off-site factors?
-
Bob,
Remember, PR is arrived at mathematically and any change to a variable will cause a change to the result. That said, usually the minor changes with loss of a link here or there, addition of same, on page changes, we do not notice right away because Google only adjusts on occasion and not internet wide (I keep asking for the schedule but they won't give it to me). Now, if you had dropped from 4 to 0 or 1, that would be different in my opinion and a signal something was amiss in the eyes of Oz.

How to analyse a big drop in external links
Hi! Can someone tell me the best way to determine what caused a big drop in External Followed Links? I have used tools like remove em in the past to try and get rid of exact match keyword links but I'm unsure if this was the root cause. Our rankings went up the 3 months after this period, but this year they have dropped back to levels from 2015. I'm wondering if this drop has anything to do with this decline. See attached. EHyIy

Sudden big drop for keyword ranking this month -Numerous possible factors... which is most likely?
Hi I have a fairly new site (domain around 1 year and 6 months old) and in December it was sitting on Google's second page for our main keyword "cv writing service" In late December we had a couple of stories picked up by the press and got some really good contextual links from a handful of well known media sites with DA60 and above. Naturally I thought this would have a positive effect on our position for our keyword so I checked and was shocked to see that the site is now sitting on page 4... A drop of 2 pages Also my site has dropped one point in DA on the Moz open site explorer I have some possible theroies for the drop but would really appreicate if anyone could point me in the right direction for the possible cause of this drop and what I need to focus on to fix tihs issue. Theories.... I made some big changes to the copy of my homepage and aboutapge a few weeks before the stories were picked up - although the copy is still similar content and optimised for my keywords I had some early SEO work done by a freelancer in the early days and I now realise that a lot of the links are very weak and on quite poor looking sites (although they are not flagged as spammy in OSE, I think they are spammy) The story that got picked up by the media was slightly off topic - it was about jobs rather than CV's - could this make google think that my site is not relevant? Prior to these stories being picked up - we took a short break from link building for a few months due to resource issues So if anyone knows if any of these factors are likely to have caused the drop I would be grateful to know! Thanks Andrew

Does Google drop links from page rank N/A sources?
Hi Everyone,
Link Building | | AMA-DataSet
I've started doing some link analysis on one of my site that has over nearly 800 links in total (which I got from the webmaster tools downloading the latest links). When I go on to Google and use the "link:www.mysite.com" directive it will only display 12 links. Does this mean Google is only counting 12 links from the link profile? Iv checked the freshness of some the links it wasn't displaying within Google to check they hadn't all expired. Links from march 2013 still don't appear. This sites link profile has been untouched for at least a year now and is full of directories many of which have a page rank of N/A hence my question. (I'm surprised it hasn't been hit by penguin!) Thanks in advance.0 -
What's Your Most Jaw-Droppingly Spammy Link ( or Promo) Request?
Sheesh. I get them every day. But this one takes the cake. It's from a woman I met once in my life on a long run with my running club. That was two years ago. Now she wants me to endorse her -- even though I know nothing about her professionally. But wait, there's more. She's not much of a runner. As it happens, I know a thing or two about fitness -- having edited a fitness magazine and worked on websites for many top fitness and nutrition pros. The idea of an MSW doing fitness programs for people with medical problems raises all kinds of red flags. She sent this Facebook IM: Hi Daniel - hope all is well! I was wondering if you can share my page with your friends, with the following message (or something similar). Thank you so much in advance! My friend XXXXXX, MSW, has been running XXXX Personal Training for the past 18 years. She specializes in exercise programming for people who have medical problems, everything from heart problems to chronic pain conditions. She works on site in her clients' homes in midtown and downtown XXXXXX. Please contact her if you know anyone who would benefit from her expertise.

Drop in "Links to your site" in Google Webmaster Tools
Last week I noticed a substantial drop in "Links to Your Site" in Google Webmaster Tools on several of my websites. Upon further investigation the reduced links were from our sister sites. It appears that Google has reduced the number of links they are counting from links in our headers and footers from these sites to our main websites. It is not affecting our rankings or traffic. Is Google doing some clean up with what they are showing in webmaster tools for links from related, owned sites? Any cause for concern?

Can being on to many directories cause a penalty from Google?
If a URL is on hundreds of different directories would that be enough for Google to penalize a website?

Ranking dropped by 7 positions for many keywords
Hey, Since yesterday my ranking dropped by in average 7 positions for most keywords. iIm not 100% sure whats the matter. I rank under the top3 for a quite comptetitive keyword since several months. During the last 4 weeks it wasn't that stady (between 2 - 4) because the competition is using an aggressiv link building method.

I'm adding constantly new content and the link building is also quite natural. Maybe I linked the same sites from some of my blogs too often... and Google may see it as a "link network". I experience the same for two of those sites. Maybe I should remove those links? Any suggestions? Thanks!0
