SEO tool to track serps, backlink profile, competitors and others

Hi Guys,
i need some help on tools that can help me and my SEO clients. I took a look at Moz, SEMRUSH, ahrefs as well as SEO power Suite. I would prefer having a one time fee than a monthly subscription. What would you recommend?

I've found that setting up ecommerce tracking in Google Analytics and then creating two custom reports is typically best for retail (one for reporting SEO revenue and one for finding sources of SEO revenue). This benefits all marketing channels and revenue dollars are a better indicator of the overall health of the SEO system. After all ranking well is only a third of the problem. You still have to win the clicks and get the sales.

I know people will argue, but you need this view to demonstrate that the SEO is fine and the store has problems... otherwise you are always suspect #1 and you never have proven value.

Plus if you are only tracking Google,Bing, and Yahoo you are throwing away up to 30% of your bragging rights.

Here are the sources of organic revenue I found in Google analytics last month:
(they include search engines, meta search, syndicated search, ISP & PC portals,safe search,...)

You can't beat Ahrefs and Semrush. You need these two if you are serious about SEO.

All SEO tools are paid for monthly. They require updates, so no one time payments are available.

All of the backlink checker tools are subscription based, even the SEO powersuite requires Search Engine algo updates from the developers.

But you can find SERP tracking tools with one time purchase like AccurankTracker, CuteRank, Ezee Rank Tracker etc..

Ahrefs is what you're looking for if you're serious about servicing your clients. You're never going to have quality software if it's a one-time fee. These guys invest a lot of time and resources in order to build their products for you and this is why they charge you on a monthly basis.

Thanks for the advice guys. Really appreciate it!

Ahrefs and SEMRush are best SEO Tools I have ever seen.

you can do one thing, try http://www.seogroupbuy.net/

You can grab all premium SEO Tools for 27$ per month only.

GB is a great option.

I have used multiple SEO tools For organic toolset, then Moz is fine but, if you need more toolset SEMrush will be better.

You can use Ahrefs and SEMRush. Those are a good fit.
