Transcript of Nibbler SEO Checker Video Review

Hi. I’m Ross Barefoot with Horizon Web Marketing. We’re about to get started with the next in our series of tool reviews for free SEO checkup tools. Stick with me. I’ll be back in just a second. Hi, and welcome back. As you know, we’ve been working through a lot of free SEO tools that do a site analysis or a checkup on the SEO of your website. We’ve done quite a few in this series, and as a matter of fact, if you look down below in our playlists, you’ll see a playlist that is all of the various tool reviews that we have done so far. Make sure that you check those out. Also, I’m going to ask you right at the front, just in case you nod off during the video, please go ahead and subscribe to our channel.

In any case, let’s go ahead and get started with this particular tool that we’re looking at today. As you can see on my screen, what I’m showing is the website for the company that produces this tool, and I’m not really familiar with this company. They’re in the UK, and the name of the company is Silktide. Obviously, as they say, their business is in helping companies to come to grips with their websites and SEO analysis and so forth. They have a free tool that they offer, and this is where it’s located. It’s at nibbler.silktide.com. You can see Nibbler at the front. This is their free tool. They also have a Pro version of this tool, and I’m sure that’s the one that you hope you will, that they hope you will buy once you try out their free check. It’s actually a pretty cool tool, and one of the coolest things starts right off in the sense that you don’t have to give them an email address in order to try it out.

We’re going to go ahead and put it through its paces. We’ve been using this particular website that you see on screen. Very plain, very boring. It’s sort of a demo site that we use for this. It’s called Artisans of Colorado. It’s not at all professionally optimized. As a matter of fact, I’ve deliberately deoptimized certain aspects of this particular website so that we can perform these checks and have something we can work with. What we did is, we went to Nibbler, and we plugged that website in and generated a report. Once the report comes back, it takes a little while for it to generate, and it comes back looking like this. Really like their interface. It’s clean. It’s easy to use. Over on the right, you have the various sections of the report. They have a numeric grade that they give you. If you’re wondering how that numeric grade is composed, they’ve got a little overview over here on the left, so you can see like the accessibility grade. They’ve got a numeric rating on each of some subsections within that particular section of the website.

I like how things will expand and contract very quickly, and they’ve got some really good advice. As you drop down through their site, you can see they’ve got top priorities for website improvement. They’ve got links to read more material. They emphasize, right at the top, social media, and so that’s what they get started with is, just start scrolling through the interface. Now, I’d like to stay at the outset, but this tool is definitely not going to give you a complete audit, but we’ve checked half a dozen tools so far. None of them give you a complete audit, a complete SEO audit. Each of them will check certain aspects of your site. Nibbler is no exception. It’s not going to be complete, but what it does, it does pretty well. Let’s start out and just take a quick look at some of these sections. It’ll take a look, first of all, at your social media, and in this sense, it looks at whether you have a Facebook page that it can find or a Twitter account that it can find.

If you drop down here, it’ll also check for any indications that there have been some social shares of the website. Now, the one thing that, and I’ll go through and I’ll tell you some of the things that I fault about this tool and a lot of things that I really like about it in a general sense, one of the things that I do fault, and it’s a fairly minor fault, is that sometimes the organization of the various things could leave something to be desired. For example, when it comes to social media, they mix in this little rating here for Alexa. All right? It shows this Alexa ranking, which is really, doesn’t have anything to do with social media, so I don’t know why it’s sandwiched in between the analysis of a Twitter, or looking for a discovery of a Twitter account, and social shares. You’ll find that, in a number of different places, there’s kind of this curious organization that doesn’t make a whole lot of sense.

Let’s drop down, though, and see where they start out. Here, and the very next section is sort of like that. The next section goes into meta tags. Usually, these tools will rank your title and your description tag all in the same area, because the title tag typically is what shows up here in a search engine result. This is, would be a simulation of a Google result, and the description tag, the meta description tag, is usually what shows up as the description in the snippet. I like the fact that they have a preview of what a search snippet might look like, and I like the fact that they will not only check the page I plugged in for a meta description tag, and for a number of other things. They’re also checking proactively for the randomly selected pages within the site. Notice they’re telling me here that these pages below that they’ve checked have no meta description. That’s a very important heads up.

If we go down a little bit farther, you’ll notice that it also gives me a review of other meta tags that show up within this page. Now, unless you know a little bit something about HTML and web design, this may not do you a whole lot of good, but it is good to be able to reference it. Notice how they also have multiple pages, so they’ve tried to keep a clean design by only showing you certain tags, and then within that block, you can go to a page two and a page three to see other meta tags. I think that’s nicely done. It’s a good interface.

I like this content designation here. It tells me whether I have thin content. That’s Google’s word. Thin content. In other words, not a whole lot of textual content on the page. It gives it to me in this nice little sort of speedometer, tachometer type of representation, which is good, because the amount of content you have is a little bit on the subjective side.

Then if you look down below here and we expand it, you’ll see that it gives me the number of words of textual content on the other pages it’s checked. I really like that aspect. Content is extremely important. Most of the tools don’t do something like that. It’ll give me some indication as to whether it has the requisite pages on the server. It’ll also talk to me a little bit about internal links. I’m not crazy about this particular section, because it makes a recommendation I don’t necessarily agree with. Namely, that you should always have text in your anchors. An anchor is a link to another page, and the anchor text is the text that you click on. Yeah, it’s a good idea to have relevant text that people can click on and that describes the link, but there are many situations where you don’t need to do that, so I have a little bit of a quibble for giving that a red circle with a white X in it.

Now, down here under Headings, it gives me a keyword cloud, which shows the relative importance of certain words that it’s discovered within the headings or the H tags of these five pages. This is a great way to visualize where you’re either weak on content or you’ve emphasized the wrong content. This is a website, for example, for artists and artwork, and you’ll notice that the word that comes up the most is the word “recent,” which has nothing to do with our topic. That would need to be something that, from a content strategy, we would want to look at.

We’ll scroll down here, and let’s see. It says, “Some pages did not define headings correctly.” This is a correct observation, because headings are often not used correctly on webpages. Headings should be in a hierarchy with one single H1 tag on a particular page. Now, it doesn’t tell me that right here. It doesn’t tell me that there should only be one H1 tag that’s the prime top-level heading of a page. This has two H1 tags, and it really would have been best if it flagged me as that not being, that that was not according to best practices, but the fact that it shows it in a hierarchy is a good thing, and they emphasize that also when it comes to their recommendations.

Let’s keep it moving here. I don’t want to keep you here too much longer. They give you some heads up about some images. It gives you information on the domain age, URL formats. I’m going to drop down here. I like the incoming links. They show number of links and number of domains. One thing I’d like to comment on that I really find to be refreshing is that they give the source of that data. A lot of these SEO checkers won’t tell you what the source is, so this is Ahrefs. A lot of people just call them hrefs, and they’re basically a service. There’s one of the most reputable in the SEO industry. They are used by tons of SEOs. It tells us that they’re using reputable information for this.

We go down here, there is one bug in their interface. It says, “Page titles,” and it reports correctly that all of the pages they checked do have defined titles, but notice here it says, “No Title,” “No Title,” “No Title,” in the breakout of pages, and that is incorrect. Probably a bug that their development team is already working on fixing. They show that there’s analytics on the site, and even give a call out to the fact that it’s using Google Tag Manager, which shows that it’s fairly recent. That is the construction of the tool.

Then freshness, they basically just look at the last modified date on the various pages in order to give you an idea. This is not that great of a metric, because often, pages can be modified in ways that don’t really matter, but it does give you all the various states for all the various pages it’s found and that you’ll basically do more than just the pages that are in the review. Now, this is at the end. It’s giving basically a little advertisement for their professional level Silktide Insites. I’d have to say if I was in the business of buying tools like this, I’d be very interested in their professional level tool based on my favorable impression of their free tool. However, we’re, this series of reviews is basically just taking a look at free tools, so we’ll stop with this one.

Now, let’s jump over real quick to the tale of the tape, so to speak. We’ve been lining up the various SEO checkers that we’ve been reviewing, and we’ve been taking a look at the internal SEO audit checklist that we use as a team. When we’re going through a site and doing a full SEO audit, we check a total 91 items, and that number tends to grow as SEO becomes more complex. You’ll see that Nibbler would help us to have cleared a total of sixteen out of 91 of those items. That seems like a really low percentage, but you can see here Google’s own tool, Lighthouse, only helped us clear six of the items on our checklist. HubSpot’s Website Grader only cleared two, so Nibbler tied for second so far in the number of items on a full-blown SEO audit that it helps us clear.

That’s it for our review or our quick walkthrough of the Nibbler tool. Overall, I’d say this is one of the nicest tools I’ve looked at so far. It says a lot of good things about Silktide, the company that produced it. Personally, at some point, I might like to check out their Pro level tool, because this was a pleasant experience. In the meantime, if you have a tool that you’d like us to check, please go ahead and put it in the comments. If you’d like to ask us a question, put it in the comments. We’ll be glad to answer your questions, or if you just have an observation. Like I said at the outset of the video, please, if you find this useful, and even if you don’t, go ahead and hit the Subscribe button and the Like button, and we’ll be looking forward to presenting more what we hope to be very useful SEO and digital marketing videos in the near future. Again, my name is Ross Barefoot. Glad to have you join me for this walkthrough and hope to see you next time. Bye for now.
