The highest number is the one that would give you the most potential return. If you have a big-time domain and can rank pretty easily on competitive keywords, start at the top. If you’re a newer, smaller site and can’t really play with the big guns yet, it might make more sense to start in the middle of the sorted keyword research list – these aren’t the “monster” keywords in your niche, but they’re also less competitive, and therefore easier to rank on.
At this point, it could be that your site is on the bad side of Google, maybe as a result of an offense and the like. The very first thing you should know is that Googlebot works differently from site to site. For instance, a well-known company with a lot of content have a higher chance of being indexed in no time as opposed to personal bloggers who post occasionally.
Thanks so much for offering this helpful tool. It is very useful. In case you want feedback, I think it would be great if you could please also consider including another column to display the linked page (i.e., the actual page that the backlink goes to on the domain). When selecting “All pages on this domain” it is difficult to know which page each backlink is going to on the domain. Thanks for your consideration.
ccTLD plays a role in stating which specific search market/location your site wants to rank in. Some examples of ccTLD would be websites ending in .ph, .au, etc. instead of the more neutral .com. If your website is example.ph, then you can expect that you’ll rank for Google.com.ph and you’ll have a hard time ranking for international search engines like Google.com.au. If you have TLDs that are neutral (.com, .org, or .net), then Google will determine the country where you can be displayed based on the content you publish in your site and the locations of your inbound links.
Given you have a good idea of where to start and are fairly confident you are speaking the same language as your client, jump start research by generating related keyphrases and long tail variants with the ever so easy to use Google Autocomplete. This tool makes predictions based on what you are typing that are a reflection of Google search activity.
Anjali, I think you should start with the Keyword Planner from Google. As a free option it is one of the best. SEMRush is great but you need to pay for it to be really effective. After GKP (Google Keyword Planner) I would also take a look at the other, more unknown suggestions Ankit talked about like KWFinder or Keyword Eye – they are quite good and will sometimes reveal keywords you wouldn’t find otherwise (for free).
Of all the tools listed in this article, Moz Link explorer is an old one & quite popular. If you want to compare backlinks between two or more domains, Open Site Explorer is worth trying. This tool works best when you have a paid account of SEOMOZ though a free version of this tool is good enough to get you started checking the backlinks of your site and the sites of your competitors.
