Search Engine Optimization (SEO), according to Wikipedia, is the process of improving the visibility of a website or a web page in search engines’ “natural,” or un-paid (“organic” or “algorithmic”), search results. SEO is done to improve your website but it can also damage your website if you’re not ethical. If you’re a newbie then I would recommend Google’s Search Engine Optimization Guide.
Search Engine Optimization (SEO) is not a rocket science. Search Engine Optimization is all about Content Creation, Link Building and Website Analysis (On-Page and Off-Page Analysis) – Keyword Research, Keyword Density, Competitor Analysis, Website Page Speed, Title & Meta Tags Analysis.
I’m going to focus on Website Analysis – On-Page & Off-Page SEO Analysis – in this article. There are tons of Free SEO Tools Online to analyze your website. So I’m going to list 25 Best SEO Tools among them to analyze your website. There are many paid SEO Tools as well such as SEOmoz, DIYSEO, Raven Tools, Analytics SEO, Web CEO, Advanced Web Ranking, Linkdex, Sprout Social, BuzzStream, Ontolo, Majestic SEO, Link Research Tools, Keyword Spy. They all offer a free trial so you can consider that as well. But, I would stay away from these tools as almost all the services offered by these tools are available for free elsewhere on the Internet (Thanks to Google Search). Anyways you can try the free trial once you have established your website.
