A month ago I've found a domain that just expired, and I registered. I've made an index, an about us page, a contact page, and a resources page. In total 4 pages, a little website. I wanted the website to be indexed, and start a SEO campaign to shoot for 1st page rankings. I've added the link to the new domain on 3 websites that have 300+ pages, and updated almost daily. Now I don't understand why the new domain doesn't appear in SERPs when I type : site : www.mywebsite.com.
I know, but after a month and with links on websites that are crawled daily I should be indexed. How do I find if it was banned before ? I've tried to use cache:mywebsite.com and Your search - cache:mywebsite.com - did not match any documents.
a)May be you have not build enough backlinks b)Use Google webmaster tools to see when the site has been crawled last time c)if your site is having PR then it is not banned!
Do a search on the domain name + banned | blacklist | spam etc and see if it's mentioned anywhere. if it is mentioned a bunch (more than once or twice), then just give it up, it's too much work to reverse the bad when a new domain is just a few pounds away, other than to do so as a technical and learning exercise. Does site:www.domain.name get any results? Go into https://www.google.com/webmasters/tools/ see if they say the site is indexed, try to establish a dialogue with them and request a re-inclusion if appropriate once you've fixed whatever problems they see. Are the links in nofollows? If the are Google & Yahoo will come and index the site (despite what they claim) but generally not return results in the SERPs. Look at the http://www.archive.org/ and see what was there. Look at the inbound links that exist from previously, are any of these "bad"?
A live link on your sig for 30 days enough for your site get indexed. The best move is to apply for a reinclusion request if you still have no luck from the suggestions above.
