on May 8th I did some SE- friendly new pages to my website and placed a link to among of these new pages on the home page, then I did a backlink on 43things, soon the Googlebot crawl my website and indexed some of these new pages, and some of these pages have good rank, Unfortunately, I haven't finished all these link pages, some of these pages haven't done, It same like this: existent page A have a link to B page, but I haven't done the B page, so B page is a 404 error, and in my google sitemaps Web crawl errors row have over 700 pages Not found. Therefore, I closed the link from the home page, and some of interior links between these new pages. After that soon, Google started to delete these new pages from its index one by one, and till about May 28th all of these indexed pages disappear from Google index. All through this course I have finished many of these 404 pages, and placed links on home page, but google have indexed any of them, and in the Google sitemaps it was showed: Googlebot last successfully accessed your home page on Jun 13, 2007. , I don't know why Google don't crawl these new pages again. Any suggestion will be appreciated.
Your question is a bit unclear to me. But getting a new site frequently indexed is not easy. Just get your site in order as far as internal linking is concerned, get good backlinks and don't worry unless it takes over a month for new pages to be indexed. Don't get rid of links to pages you want indexed, that's just going to be cause for new pages to not get indexed.
But it's difficult for me to get quality backlinks, my site PR=1, If del.icio.us and digg will help me?
Do the basics to start with for link building 1. Use a directory submission service and whack out 100-200 or so listings... $30 2. Get articles written (find affordable writers - $25 per 1000 word piece) and use an article submission service (around $25)... If you do your on-page well and ensure a good cohesive link text for the back links, you can go a long way with very little. Then start working on the more quality back links... the above is simply the starting point to get a site well indexed and going. You can even rank for some not so uber competitive terms with the above method alone....
Hey I am also confused your questions. pls give me your site name. so i can see your site status in google.
Most bloggers will happily link to PR0 sites as long as you have some good content. Most people don't even know what PR is. Try blogging about some cool stuff and you should start getting some readers who then might link to you.
