With a tight budget in mind, I'd like to know from people in the business what SEO methods are still a viable option to rank a site in 2015? With budget restrictions I don't see an solution that doesn't involve some greyish methods. I'm new to SEO and from what I can tell around the web, I should be looking at the following: Private blog network built on expired domains with high quality content (as tier 1, Web 2.0 + highish quality links from GSA as tier 2, tier 3 same as tier 2 on larger scale) PBN content promotion via social media PBN content promotion via link outreach PBN content promotion via broken link building Competitor backlink profile replication Guest blogging Blog commenting Parasite building/boosting via GSA Citations Possibly a few SAPE links? With the main focus on the PBN for ranking the site, here's what I think I'll need: 10+ expired PR2/3 domains for PBN SEO Hosting 10+ cheap shared hosting accounts 10+ proxies VPS Copy of GSA Search Engine Ranker Copy of GSA Captcha Breaker + Death by captcha Copy of Kontent Machine 3 Ahrefs account All comments, suggestions, criticisms more than welcome. I'd just like some solid information from people actually doing this professionally. This model will be eventually be used on a large UK based Ecommerce site once it has been tested thoroughly.
