there is no new SEO techniques to get back links, most of them same. If you do forum posting, blog commenting, and press release i think you will increase your back links of your site
Their are no new ways to build links but the methods of getting links from the sources are changing and always in evolutionary phase.
Hi, If you can complete old ways then search for new way because according to me if you are submitting your site to 10000 directories then in duration of submission many other directories come online. Same with other like article submission, social bookmarking, theme related one way links etc. So new way and old way both are same at one sentence that search always theme related website or do follow directories or do follow article directories or new social bookmarking sites and submit or list your website there on regular basis because your competitors are doing this regular. I think main common rules of seo and link building are same like past. Need to manage only quality. Thanks
