Top 25 Free SEO Tools For On-Page & Off-Page SEO Analysis

Search Engine Optimization (SEO)

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.

    This is very unique list and i have found very useful SEO tools here.

    • http://www.maheshone.com Mahesh Mohan

      Thanks Ali! Do mention the tools if I have missed.

  • http://shalusharma.com/ Shalu Sharma

    You have a good list of tools here. I have not heard of many of them but I will go through them and look at them too see if I can use them. Thanks for list.

    • http://www.maheshone.com Mahesh Mohan

      Always welcome. I will soon do a dedicated post for Competitive Analysis as well.

  • http://ppcseo.org Morgens

    Nice list Mahesh.

    I like to add two free keywords tools: KeywordDonkey and Keeyword

    • http://www.maheshone.com Mahesh Mohan

      Please provide the URLs and I will add them if it’s good.

  • http://yodaquotes.org/ yoda

    I love SEO book and submit express, been using it for years.

  • Aime

    Don’t forget http://KeywordA.com This tool allows to use keyword density analysis to find search terms your competitors are using on their pages, where each term is used and weights of every term in various types of page content. It also allows to select the keywords of your interest and compare their stats against your page.

  • Ron James

    Where’s scrub the web? Most of what you have here are tools that do not work. SEO Book is a total joke and SEOmoz for example, weekly crawls and rank tracking violates every single search engine’s terms and conditions, but that is SEOmoz’s biggest SEO tool (hahaha). Google makes it very clear in their TOS this practice is in violation of their TOS. And what good does it do you to know that your competition is working on their SEO and they have now outranked you? Real SEO tools will help you discover the reasons others are outranking you.

    Search engines index “content” and they are looking at your web pages. If you are not making changes to your content, you are not doing SEO. Real SEO professionals know this and that is why they are expensive. I admit I am a member of stw and it was the best choice I have made. I have also purchased SEOmoz as well as SEO Book. While they both have a few very good videos, their tools are horrible and do nothing for you. I won’t publish a web page without first using stw’s tools.

    Just my opinion,
    Ron

    • http://www.maheshone.com Mahesh Mohan

      Thanks Ron,

      I guess ScrubTheWeb don’t have a free plan. All the above mentioned tools are free or at least have a free version. That’s why I haven’t featured SEOmoz here. And yeah I am doing another blogpost with a comprehensive list of SEO Tools. Let me know if STW offers a free plan so that I can try and feature on the next post.

      - Mahesh

      • Ron James

        Sorry, I replied to the email. Here’s my reply (sorry):

        Actually STW does offer a free plan. The only difference is that they do not make you “sign up” to use their free tools like these others do. Even Google makes you sign up and you can’t use their tools on your competition. I personally like STW’s business model better don’t you? STW provides a free analyzer, free and “accurate” meta tag creation tool and a free submission tool as well as free help. Instead of making their visitors sign up (so you end up on a spam list), STW lets the world use their tools free of charge without you giving up your email address. Compare STW’s free tools to SEObook’s free or premium tools and you will see what I mean. STW’s free tools are better than any of the other premium tools out there. If their free tools say you have a problem you better take a closer look. SEObook is a total joke and for the most part their tools don’t work and were not developed or even maintained by them. STW blows everything else out of the water. I’ve been on-line for years and I thought I had it together, but I was totally wrong.

        • http://www.maheshone.com Mahesh Mohan

          Can you please give me the link to STW’s Free Plan? I don’t see any links to free plans on http://seotools.scrubtheweb.com/

          • Ron James

            On every single page throughout their site provide links in the left menu. Remember, it’s not a “free plan” it’s just plain free (no sign up required). Here’s direct links to their free tools:

            The best free meta tag analyzer:

            http://www.scrubtheweb.com/abs/meta-check.html

            which does a lot more than just analyze meta tags. It analyzes your robots.txt file, your server’s header responses, encoding issues, search engine visibility score and a whole lot more.

            Free meta tag generator tool:

            http://www.scrubtheweb.com/abs/builder.html

            Their premium tool does a lot more and automatically inserts in your page if you want. It’s totally awesome because you can’t make a mistake.

            And a free submission program:

            http://www.scrubtheweb.com/abs/submit/

            And another thing I like about STW is that everything is advertiser free. No google adwords and not google analytics or other embedded tracking code. They must be selling a lot of memberships if they don’t have to subsidize like all these others obviously need to. And as a member I can ask the CEO any question I want and I usually get an answer within minutes. If you have a question about search engines and how they work, nobody is better than a search engine I feel.

  • http://cotos-eweb.com Market Samura.Traffic Travis

    It continues to be observed which is proved by the survey too
    that a majority of of the people who’re searching the world wide web with the help of search engines like google such as Google, Yahoo and Bing etc only open the web pages that show up on the first page with the search result. Magic Submitter invented the SEO scheduler, which can be perhaps the greatest revolution ever within the history of SEO software. You cannot optimize your website properly in case you don’t have an idea what keywords you should use.

  • John William
