                                    Sitemaps are a great way to communicate with the search engines. In robots.txt you can tell search engines which parts of your site you do not want them to index, in the sitemap you can tell search engines where you want them to go.

                                      • Just type in your XML Sitemap address and click on the red colored Validate button.
                                      • The tool will check if all the links in the sitemap are working properly.

                                        What an awesome list, there are names which I didn’t know until now. Although I have tried many of them and yes they are best for on page SEO as well as keeping the price as free. I am gonna try every tool you mentioned here and I think this will keep me busy for almost a week ๐Ÿ™‚ .
                                        Anyways thanks for sharing this info.

                                        Hi Navneet,

                                        You did a splendid job here, I know On Page Optimization is very crucial since the launch of Google Panda as it helps to deliver best user experience and also been liked by Google.

                                        I was aware lot of these tools but some of them are completely new to me. Surely going to try new tools and see how they can help me. ๐Ÿ™‚

                                        Really good list. Too bad the list had to be capped at 25 … there are so many good (and free!) tools out there. Here are a few more indispensible tools: The WebDeveloper Firefox Plugin – I’d be lost without it. I also really like the Quirk SearchStatus Firefox Plugin. There are a few nice features but the best feature (as far as I’m concerned) is the rel=canonical icon in the URL address bar. It “lights up” when the URL you’re viewing is different than what is set by the canonical tag. The Moz Firefox plugin has also become an important tool in my toolbox.

                                          The list was getting quite long and I wanted to have a fair balance in each categories. No doubt WebDeveloper toolbar and Quirk SearchStatus Firefox Plugin are great and I personally have these installed in my browser as well but again would have made this blog post more on technical tools only rather then the onpage tools.

                                        Nice list, a couple in here that I’ve never come across before. I’m off to try out Feedbot!

                                        I am familiar with some of the tools but I did not realise there were so many others………well done!

                                        Looking forward to checking them out!

                                        This is a great collection that you have put together.
                                        Many of these are the subject of many similar posts, but it’s always good to keep it fresh.
                                        Some tools drop and better alternatives emerge.

                                        Absolutely love Screaming Frog and paying for it is well worth it!

                                        indeed a very useful list of tools to improve the search engine optimization.

                                        Excellent article, thanks for sharing! Unless, I am not understanding SEO-Browser, I think they are no longer free, but that’s okay. The other tools in your article are great, thanks again!

                                        Structured data tool is provided with google webmaster tools as well.

                                        Screaming Frog and Google keywords planner are one of the best tools.

                                        This is a very interesting article, so helpful on my queries about SEO. I am looking for more information about Search Engine Optimization tips for quite a long time already. Although I know some of the tools mentioned here, but some like Site Condor, UbberSugges, SEO-Browser and 8 other tools are, I don’t know. Thank you.

                                        This is a great summary of many of the SEO tools that I use daily. There are some great Chrome add-ons also – perhaps we’ll see a list on those.

                                        Thanks Navneet for the great on-page optimization tools. I really don’t know many of them such as URI Valet, Feedthebot, Site Condor etc… and they are completely new for me. But now i would like to a give a try to those remaining.

                                        These 25 tools are great and I hope you keep them updated. Web engineers need deep dives into analytics so they can use the tools wisely. Many SEO professionals now use page structure and content enhancement to raise Google visibility.

                                        These are SEO weapons! You need to have this while auditing SEO for a website. Thanks for sharing the list. I haven’t used all these but used many.

                                        Awesome post. Few of these are new for me like siteliner, KeywordTool.io. But in siteliner, the duplicate content checker is not good. It checks side bar ‘archive’ , ‘related post’ that give duplicate content results die to their title. BuzzStream Meta Tag Extractor is really good. It saves lots of time. Thanks

                                        I’ve read a lot of articles that offer free SEO tools but this has got to be one of the most complete guides I’ve seen. A great mix of older, more traditional tools as well as some new ones which I had personally never seen. Cheers!

                                        Thanks. Pretty huuuge set of tools.
                                        However, I would put my 5 cents for the other keywordtool http://sg.serpstat.com as it has question only mode useful for title generation.
