Welcome to the Q&A Forum

What is Sandbox? In order to avoid something like Sandbox, one should know very well what Sandbox is. But, nobody knows if Sandbox does exist, so let's just focus on the main problem here: How do I get my pages indexed? I have tried over years a lot of techniques, but I found only one that seems to work. If your site is not dynamic, make it so. Create the sitemap and the feed (I recommend RSS 2.0). Put your sitemap in your robots.txt. (last line, like this: Sitemap: http://www.yourdomainname.com/sitemap.xml). Submit sitemap to Sitemaps section in your Webmaster Tools' account. Submit your RSS feed to main RSS directories (just google the words, and you'll find plenty of them). Start with FeedBurner, to please Google. Wait a week or so and you'll see that your pages will start appearing in index. Good luck!

Try to avoid generating (or worse, buying) +1 votes from untrustworthy sources. My advice to you is this: build a great Google+ page for your website (fill all the details, and even add content, as valuable as you can). Then, check the top 50 pages on Google+. Add them to your circles. And wait. People will start appearing from the network and will start adding you on their circles. When you get the first 100, use the share options of the circle and write something like this: "If you like our content/info, please give us your vote by clicking on the +1 button on our front page" and place a link to your entrance page. Now you'll get natural and good votes. And, yes, in my opinion, because of the trends on the market, with social media becoming a key factor, I even suspect that soon the +1 will indeed replace the PR (Page Rank).

Already resubmitted the front page to Google using Fetch as GoogleBot and Submit to index from Webmaster Tools. Also pinged the page to all main Google local SE. On the other hand, sitemap (or site in general) cannot be in sandbox, as it appears in more than 5000 daily searches :). And I have more than 1000 pages in index. And they all appear when I search for the main keyword of each and every page :).  The only issue is the main page.

Now, before it disappeared, I have noticed another strange behaviour. My front page displays, randomly, one article from a specific table in my database. Every time I was adding a new article, again the front page was gone from searches for a day or 2. Then everything was back to normal.

Still, my question is this: If something is wrong, why Bing and Yahoo are displaying my front page for the main keyword? And Google not? Somehow, the algorithms are not that different.

A blog network is a group of blogs that are connected to each other in a network. The advantages of such networks are pretty obvious, from the SEO point of view. Fast indexing of new content, ping and trackback, one way and 3-way links, article marketing, etc... Read this article for further details and some examples: What is a blog network?

Now, finding new networks in your niche is something that you need to do it yourself. Just do a research on Google and you'll certainly find what you're looking for.

I was wondering if someone has encountered the same problem as me. I was doing some changes on the frontpage of one of my clients' website, especially some redirections, and my site has disappeared from Google for the main keyword on the page. So, if I look for my page on Google, instead of seeing my page first, I no longer see my page, at all. All I've done was a 301 redirection from index.html to the domain name. Now, I changed everything back to how it was before. More precisely, I've done that 2 weeks ago. But, no change in Google. I checked Bing and Yahoo, my site appears first when I search for that specific keyword.

Any ideas how long will it take for Google to see that I am not doing anything wrong with redirections? Or any idea at all?
