We had a very successful site written in html that had approximately 250 items and attracted more than 18000 visitors/month.
In April we launched a replacement ecommerce site in php with 2000 products that barely reaches 5000 visitors/month. I have checked Google and found that five months after launch only about 1305 pages have been indexed by Google.
I have added an RSS feed that lists the sitemap as well as submitting the sitemap.xml feed to Google. Is there anything I should be doing to get the rest of the site indexed or do I have to rely on Google eventually indexing the new pages?
Would it help if I continually modified those pages that have yet to be indexed so that the generated site map indicates recent changes?
