I would like to share experience with strange happening regarding not indexing of landing page's.
This is way how i work always. Customers chose terms and then i build
optimized landing page's with unique content completely integrated into customer website qua design and coding.
In 98% situations all landing page's are usually indexed within 1-4 weeks.
However there are some situations when for example from 20 LP only 1 is indexed or from 50 only 3 etc...
By every customer i check always robots and nofollow tags.
Then check of content is unique etc...
All landing pages are 100% integrated into customer existend site qua design, coding and all are visible from home page and the rest of the site (full integration).
It does not matter but all landing pages are furthermore submitted via webmaster tools center to let know that they exist.
Finally after 4 weeks of waiting is one more experiment done whereby is one landing page (which still not indexed after 4 weeks) submitted to soc. bookmarking site's (10 - 12 big major soc. bookmarking sites).
Google respond very quickly and did indexed soc. bookmarking sites where this page is submitted. Despite of the fact that dofollow link to landing pages is now visible on soc. bookmarking sites the landing page in question is still not indexed.
I know that it is difficult without an insight into complete project to give me any hint but is there still anyone who have any clue what is reason for selective Google qua indexing.
Of maybe someone had same experience and have hint what to do in similar situations.
This started for the first time to happened since a month a go. Probably it have something to do with Caffeine because in past i have never faced such a issues.
