I have a website with 5 million pages, purely targeting traffic. Its seo was automated with templates. Out of 5 million, 1.5 million pages got indexed and for last 4 weeks its not showing any increase in webmasters .
Is their any specific things I can try it out? I have or tried all below mentioned. Please help me out...TIA
1- Sitemap in place ( not having more than 50k urls in one sitemap)
2- Checked Robots.tx ( not blocking any required pages)
3- Website performance - is good enough ( loading at 2 sec)
4- Interlinking - Quite good
