Main page of my site has top ranking in google. But when i add inner pages they also have top ranking but for 3 days maximum. After that they disappear from SERP forever and never come back. It doesnt matter if i put links from other sites to them or not, veriefied several times already. I also put link to them from all pages of my site. How to make inner pages that will never disappear from SERP ?
There are no SEO tips/tricks that can maintain rank of any page forever. Search engines keep updating their algorithm against malicious technique.
Create links for your inner pages for which you are willing to bring on top in search engines You can use Directories, forums and social media sites for getting links for your inner pages
There are many methods for inner paeg ranking.Just build inner link building methods.You can use deep directories,social bookmarking,forum signatures etc for it.
Check the very last page of the google results (900-999). See if your inner pages are listed there. If they are you might want to change your internal linking structure. Do some reading about the "end of results penalty" or "-950 penalty".
I love this site - I'm new here, yet a seasoned SEO manager. Seeing all these great suggestions is inspiring! Do you use at least some unique keyword phrase or phrases on each inner page, and also include some of the keyword phrases from your home page on them? Do you provide links within your content on each page that go to another page on your own site? Do you have each of those pages as a main navigation link from the home page and do you have all your top pages as main navigation links on every page? Do you also then put those navigation links in plain HTML text format at the very bottom of your site (on all pages)? Do you include Link Labels for all your top page links from page to page? Is the content on the inner pages unique enough but related enough to every other page? Is it quality content? is it robust content? There are countless things to do - everything that involves high quality SEO on a home page needs to be done on every other page. When Google determines that you have truly done all the SEO work we all describe, one day you may even be rewarded by seeing your home page in the number one position, and just below that, see six or eight of your inner pages listed in Google's "site links" method, and yet another page in the number 2 Google position. Every time one of my client's sites has that happen, it's like magic - and reaffirms all the hard work was worth it!
