An SEO audit is the process of following a checklist or tool (or both) to evaluate how search engine friendly a website is. An SEO audit will consider on page factors (on the website itself) and off page factors (including inbound links and brand search volume). A good SEO audit will consider the crawlability, indexability, and quality score of a website based upon up to date Google ranking factors.

There’s always more than one way to ask a question. Consider synonyms and semantic variations on keywords describing your services. Google’s RankBrain technology recognizes synonyms and expands their search results accordingly. Google also punishes websites for stuffing their content with repetitive keywords. Synonyms and variations can help you to reach a larger audience and avoid Google penalties for keyword stuffing.
This will instruct search engines to avoid this specific link. The attributes found above helps define the relationship that a page or content has with the link it is tagged with. Nofollow links are mostly used in blogs or forum comment because this deems spammers powerless. This was created to make sure that inserting links is not abused by those who buy links or sell them for their gain. As a webmaster, it is your job to check your pages for these links. Inspect the code and see if the links are tagged with its corresponding follow or nofollow attribute.
It’s important to note that entire websites don’t rank for keywords — pages do. With big brands, we often see the homepage ranking for many keywords, but for most websites this isn’t usually the case. Many websites receive more organic traffic to pages other than the homepage, which is why it’s so important to diversify your website’s pages by optimizing each for uniquely valuable keywords.

I recently paid to use the moz keyword tool, and its been really insightful. (but expensive!) it helps find synonyms and other wording that i never would have thought to include in my post. also, i’ve realized the importance of allowing comments on blogs, as people discussing the topic seem to add those terms naturally to the post. thx for the post!
SEMrush is a very useful tool for both researching competitors when starting a site or for growing an established site. I really like to find weaker niche sites that still seem to be ranking for lots of keywords; SEMrush helps me see what they are ranking for and what I can potentially target. You can also see what keywords you’re on the cusp of ranking for with your established site - another very useful feature.  

As for duplicate content, Google gets confused when you create and publish articles with similar content, and this eventually leads to indexation issues. Keyword cannibalization happens when the owner focuses his effort on ranking for a particular keyword from several different pages. When this happens, Google won’t acknowledge multiple pages; they’ll only focus on the best one thus making the other ones useless and inaccessible to search engines.
Hey Alex – this is a good question. No tool is going to be spot on. My advice is to not look too much into the accuracy of the metrics, but look at it more as a relative measure. I’m finding Ahrefs to be a good barometer for keyword competitiveness, but I’ve also heard great things about KW Finder lately. I think it’ll more come to personal preference. Both are solid options.
2) SpyFu: I suggest to have paid account on SpyFu. I just need to find my competitors who using Adwords and review them using this tool. It will show me what ads and keywords they are using. Note that my competitor who paid for that particular keyword knows exactly that it is important for his business including recent trends. Also using SEO feature you can input any URL and find our which keywords they are ranking for.
1) Ahrefs to quickly see “the big picture” when it comes to any keyword I'm researching. I can instantly see the top holders in the SERPs. I then immediately take the top holders list and go check out their sites. I need to make sure I can beat them content-wise, otherwise I will search for another keyword to try and rank for, or perhaps go down the long-tail route. The Ahrefs tool and data quality get better and better every year. It's one of my favorite tools.
Every online search starts with a keyword. This can be, by simply typing in your keyword into the Google search box or by using voice activated search. Based on the user input, search engines will return the most relevant results to answer the query. Optimizing your content and ranking for the right keywords, determines the success of your website and your online business.
KWFinder was developed and created by Peter Hrbacik. He is amazing at providing great support for the tool. They have live chat on their website, which I have used quite a few times during the day. Also, their email support is also awesome. Below are a couple email conversations I have had with Peter. In this first email I suggested that they make the category headers clickable. Peter responded within 24 hours and said they will probably change it. And a couple days later, the change was implemented.
They also seem to be getting this wrong often enough that I've got less confidence that the keywords that make up these groups really belong there. I recently tried to check the volume for the keyword [active monitoring] (the practice of checking on a network by injecting test traffic and seeing how it's handled, as opposed to passive monitoring) and the Keyword Planner gave me the volume for [activity monitor] (aka Fitbit).

What this does is give you an idea of how realistic it is for you to target keywords with high commercial value. You want to go after keywords with some volume, because they’ll have a better return in terms of traffic. But you don’t necessarily want to go after the most competitive keywords, because you’re less likely to be able to rank for them. You’re looking for a sweet spot.
If you get an "Action Against Links" notice - there is no plea you can send. Your site or some pages of it - would basically have a lot of rankings. To fix things you need to fix links and any other on-page and other issues and wait for the re-crawl to happen. Since the Penguin algorithm is not real-time... you will see ranking gains faster and you do not have to wait for a data-refresh to happen to see any benefits of your link purge or SEO fixes.

We’ve discussed the mechanics of search and the importance of link popularity. We’ve explained that that a page is more likely to rank if it is part of an authoritative website and that a website is authoritative if it has many links to it from many other websites. Now it’s time to actually estimate authority of the websites that rank and therefore estimate the competition for a given phrase.

Hi, Great article! the tools you listed in this article are great. I tried only Keyword planner and at present I’m using a long tail pro for Keyword search but I didn’t try the other tools you said. Because I’m new to this and now only I’m learning one by one. At this time, I thought this guide will help me to know more about keyword search tools. It’s wonder and thank you so much for this nice guide.
Pro Tip: the more love your website needs to be optimized, the more you should consider investing in a website redesign or a whole new website built with SEO in mind from the start. Key Medium can conduct a thorough technical website and SEO audit and walk you through recommendations to develop an action plan customized to your business goals, needs, and budget. 

Yes solid keyword data dramatically changes the game as far as rankings go. I have seen many tools that provide Cost per click stats and meaningless charts that confuse most users. the data Jaaxy provides helps drive “organic” traffic to your site on a consistent basis which will out perform PPC sites every time. I like how you say thinking like the end user, as I feel that way when I search. I dive into what people are looking for and it really helps drive content idea’s. I have seen great results from that.
