An alternative or perhaps companion to keyword research tools, operators can help you identify the popularity of certain keywords and keyword phrases when you are optimizing a site.
Operators = words you type in the search field before the KWs to help determine competition.
1) Allintitle: This operator tells you how many web pages globally have the same keywords listed in their title tags.
E.g. “Allintitle: thai restaurants” is typed into the search field. The SERP then reports back that 744,000 web pages on the web contain both these words in their title tag.
2) Intitle: This works the same way as Allintitle, but shows all web pages that list any of the keywords. So in the example above, if you used “intitle:” instead of “allintitle:” the SERP would reflect all websites that contained either the keyword “thai” OR the keyword “restaurants” in their title tags.
3) Allinanchor: This operator allows you to see how many links on the web are using the specific keywords.
I prefer to use keyword research tools like Keyword Planner for SEO, but these are definitely good to know!
PS – Google is going to be changing its Adwords Keyword Tool to Keyword Planner soon. I’ve written about the changes and how they compare on my company blog if you’re interested.
