With the help of some SEO experts, I've compiled a list of useful tools to help with on-site optimisation, link analysis and more. 

While some of these tools are paid, the majority are free to use, or at least offer a limited service for free users. 

Thanks to Kevin Gibbons, Irish WonderNick Chowdrey and Pete Handley for their suggestions. 

Keyword research and content planning

Google's Keyword Planner. Used as described in this article, the keyword planner can be a valuable tool for identifying opportunities and finding ideas for content. 

faq fox. This is a useful tool for finding popular questions that people ask in your industry. 

Yandex Keyword statistics. For those targeting the Russian market. 

Baidu Keyword Tool. As above, for China. 

Google auto complete. 

Google Auto Complete

Ubersuggest. Enter a phrase and ubersuggest will provide a bunch of suggestions around that term. 

On site tools

Searchmetrics. The research section is free and gives us so much juicy info.

Screaming Frog SEO Spider. This is useful for identifying a multitude of on page factors and highlighting where there are issues (with page titles and descriptions being too long or too short, finding broken links or internal redirects that need to be updated).

Schema Creator. If you want to look at how to start getting rich snippets in Google Search results, but don't know how to write the code for it? Schema Creator can help you generate this depending on the type of rich snippet and structured data you need to implement.

Page Speed checkers

Google Page Speed Insights. Speed matters, and this tool will score sites for speed, with some useful suggestions for improvement. 

WebPageTest. Along with Pingdom, these tools provide insights into the elements that may slow page loading. 

Pingdom

Link analysis

Majestic. Another good top-level analysis of backlink profiles that comes free.

Broken links checker. Does what it says on the tin... 

ahrefs. The free version provides good top-level backlink analysis. 

SpiralDB. This is handy for doing a quick check on a web page for a domain, using LinkRisk, Majestic, ahrefs and SEMrush data. 

Other tools 

Jellyfish Google penalty checker. This looks at site data, plotting Google updates on a timeline. 

Copyscape. This looks for sites copying your pages. 

Wayback Machine. Here's what we looked like in 2001...

theMediaFlow's HREFLANG XML sitemap generator. This can be used to generate international targeted XML sitemaps for various languages and regions.

Moz. The pro tools here contain lots of useful data, including link analysis, social analytics and keyword tracking. 

PI Datametrics. This paid tool allows you to track your own and competitors' rankings over time, and shows which pages are ranking at any given time. Its especially useful for avoiding issues with cannibalisation of ranking by competing pages from the same site.

Jellyfish search snippet tool. This allows you to test how your page will look in the SERPs. 

Google Webmaster tools (which as of the date of this article being published has been rebranded Search Console). Essential for checking crawl errors, keywords, and any notifications from Google. 

Spyfu. This provides competitive intelligence, both organic and PPC visibility data, as well as historic rankings with Google update clues over the timeline and a handy option to compare two or more sites and the chance to spy on competitors' profitable keywords. 

 

BuiltWith Technology Profiler. A really useful tool to understand what web technologies are employed on a website - server types, content management systems, code frameworks and much more.

Buzzsumo. Among other things, this can analyse the performance of content and the backlinks each article attracts. 

 

SearchStatus. A Firefox plugin offering quick access to data about a site including Whois, Google indexing of the site, link report for a page, etc.

SEMRush. This provides organic visibility and PPC visibility data, as well as some useful data on competitors: 

Archive.orgCheck what a site looked like in the past, how long has a site existed on a domain etc.

Ayima Pulse. This provides insights into rankings and movement in various sectors. 

Which tools do you use? 

This is a long list, but we may have missed some useful SEO tools. Please suggest any below and let us know why they're useful to you. 

(Bear in mind, our spam filter tends to frown upon links in comments, so just provide the name of the tool rather than the URL.)

Perhaps it would have been worth sense checking the article before going live? Yesterday Google announced that Google Webmaster Tools has been rebranded into Google Search Console.

A well-respected site like yours should pay a bit more effort into this kind of things IMHO.

@Andrea - To be fair, the announcement was issued at exactly the same time that we published this article. An amendment has been made in the text above. Thank you.

Try the Panguin Tool for checking your site for algorithm penalities. Unlike the Jellyfish one you mention, Panguin doesn't require you to be "approved" before you can use it

'Decibel Insight' helps SEOs to bridge the gap between data from GA and site changes. We should be at a stage now where behavioural analytics/insight tools should plug this gap, to help SEOs understand the what/why/how/ of their GA data. This will put an end to rash decisions to make site changes before a proper analysis has taken place.

We provide a free trial, but would also encourage people to check out all tools on the market to weigh them up fairly.

Will Huggins, very neat tool you guys have put together there! Easy to follow and lots of info!

Graham Charlton, this list must have taken lots of work to put together and I appreciate that big time! I've found it super helpful and I think lots of people will take something away from it.

One tool I've been working with for a while now is CanIRank, a keyword research tool and pretty much the only intelligent one out there that will not only run the data searches, but do all the interpretation for you. Great for anyone who's sick of compiling numbers in excel sheets to hunt for trends!

Sam Gooch, Digital Marketing Manager at WooRank

You've mentioned some great tools here, with a few that I have yet to try out. One that's definitely missing is WooRank (https://www.woorank.com/) which allows you to carry out an instant analysis of your website to highlight areas that could be harming your rankings, and other things that will improve your SEO.
