I had a site setup with a "Coming Soon" landing page for a while with a simple page title; I launched the site almost 4 weeks ago now I would say with an updated page title and Google are yet to update the page title, yet they have indexed all my other pages on the site, so they have been crawling the site (which I can also see from Webmaster Tools).
I uploaded a sitemap within my Webmaster Tools account and submitted that, no change. I then found out that Google may not bother checking the page to avoid caching the same content over and over again if I had not put a "Last updated date" for the appropriate link within the sitemap; so I did that and re-submitted the sitemap, and it shows it has now been processed, however upon searching Google my site title STILL has not been updated.
Please someone help!!!
