Ouch! I must have hit a sensitive spot with a few, eh? I'll be glad to extend my apologies but I'm not too certain what I'm apologizing for. Sorry, I'm not taking any responsibility for Google's actions, those are outside of my control. ;)
You see, that is why I don't follow those Part I, Part II and Part III topics. Typically they provide little definitive insight as to what might be happening. Everyone has their own issues to deal with and rarely are two the same.
So, if I'm apologizing, it would be for not following those types of topics. I used to, and it is too stressful to watch the SERPs. Now I just pay attention to overall statistics and the bar graphs continually on the rise and my clients ROI doing the same. ;)
There should be no reason whatsoever for you not to add new content. Being caught up in those 50 page topics will have you chasing every whim of the algo. Is it worth it? At some point you have to stop and ask yourself, why am I doing this. The outcome at the end of the month is the same. Or, maybe it isn't. If you are constantly tweaking pages to chase the shadow of a recent algo, then you will lead a very stressful life. ;)
There is no Xmas Debacle as far as I can tell. It appears there is movement in the SERPs and it just happens to be a small group here who are being affected negatively. I hate to hear when that happens but it is all part of the process. I've found that 9 out of 10 sites (not their home pages) that drop out of the index all of sudden after being there for years, come right back shortly thereafter. And again, it appears to happen when Google is increasing the size of their index.
Now, if you've watched yourself slide from 1, 2, 3 downwards to 8 and then drop to page 2, there is something to investigate. It too is usually a side effect of the index growing or possibly a PR reiteration.
If those pages that are dropping didn't have any PR to begin with, or very little, I'll bet they are probably tagged as Supplemental right now and on their way out of the index. But, at some point, they will come back into the equation.
If it's an entire site that has gone missing (home page gone, not appearing for company name search), then you most likely have a serious issue at hand. I emphasize most likely. That typically does not happen with an established site. There are a few things that could have happened and it is all relative to what you've been doing over the past 90-120 days in regards to site changes, servers, etc. So many technical things can have a negative impact on one's indexing. If you've think you covered them all, think again. Go back and double, triple check everything. Run a DNS Report. Check your server headers. Run a Copyscape Report. Test your server? Are you on shared IP? How many others on that IP? What percentage of those are questionable? Man, there is just too much to list.
If my livelihood depended on the Internet, which it does for the most part, I'd be looking for a cause and/or causes. I sure wouldn't be worrying about adding any new content, that is a given.
Of course they will. It may not happen as quickly as you'd like, but they will get spidered. That is the easy part. Getting them ranked is the part to be concerned with. Google will spider anything.
At some point they should be seen in the SERPs. There is this whole group of other factors though that come beforehand. Its that "chicken and the egg" thing.
Low PR site, lots of lower level pages sitting at levels 2, 3 and 4. If internal linking is not done "just right" and if there isn't enough juice to pass downwards, it is going to take some time to funnel that PR to those pages. It doesn't happen overnight. It does if your site is at PR6 and above. Anything below that makes it a bit tougher although this may not apply to everyone. If you are at PR5 and the bulk of your competitors are also at PR5, then you can assume that your PR Cap is probably at PR6. Meaning that you won't see anything higher than that PR6 for quite some time. This is an average and not an absolute. Certain sites will obtain higher PR than others due to the nature of the beast. ;)
This might be going a bit too far. Why would something that Google knows nothing about yet have a penalty against it?
Even though they are the ONLY such pages, they haven't been out there long enough to establish any sort of authority. Stop chasing the algo and continue on with your content building plan. It will all come in due time. This time next year you'll be patting yourself on the back that you no longer have Googleitis and are leading a stress free life while making money in your sleep. :)
I'll hope that they are still being created.
If your only reason is to make an income immediately, then you will continue to stress out like this and think of all sorts of crazy things. Thousands of quality content pages are going to generate an income. It is a given.
I don't see that they've made any major changes with the way they handle SERPs. Not in the past 12-18 months. Mind you, I said major changes. Their technology continues to advance. They lead the way in relevancy although many would question how relevant they are. And, they are still "King of the Hill". They have some contenders and I'm one who hopes that the playing field becomes more balanced in 2007.
Oh, I'm sure they take each algo tweak very seriously, their livelihood depends on it. Collateral damage is a given with an index as HUGE as Googles. If a few hundred websites fall off the face of Google Earth, that is not going to phase them.
