Keyword research is a constant process. Trends change. Seasons change. Popular terms and catch-phrases change. SEO and marketing agencies are a great resource for ensuring that keyword research is done on a regular basis. You should refresh your research at least quarterly, ideally monthly, to stay ahead of your competitors. Partnering with a reputable SEO agency is a great way to ensure you’re always ahead of your competition.
You can also indicate which pages don't need to be crawled or are not important. You call the Googlebot to crawl and index your site from inside the Google Search Console. However, do note that although Google "looks" at your sitemap - Google is more interested in doing a raw crawl of your site - jumping from one link to another to spider all the pages in its database. By doing that, it also forms a link map of your site into its own index - which tell it which pages on your site are the most important pages (they are the ones that have the most links - the most prominent links).
There is a myriad of search algorithm updates, erratic market trends, increase in competition, among other things, all the more reason for you to be always on the move. With the help of the different tools that you can easily access with just a google searc>h away, all of these can be done in a snap. If you are committed to these practices, SEO ranking would just be a light feather on your workload.
I recently decided to go with ahrefs after using spyfu for a couple years and trialing secockpit. I was a moz client for awhile too about a year ago. I found spyfu data to be sketchy (or just plain wrong) fairly often, and moz, I don’t know, just didn’t seem like they were really into supporting what I wanted to know. secockpit was achingly slow for a trickle of data. ahrefs isn’t nearly so graph-y as spyfu, but they are so blazing fast and the data is so deep. I enjoy it a great deal, even if it is spendy.
The higher the search volume for a given keyword or keyword phrase, the more work is typically required to achieve higher rankings. This is often referred to as keyword difficulty and occasionally incorporates SERP features; for example, if many SERP features (like featured snippets, knowledge graph, carousels, etc) are clogging up a keyword’s result page, difficulty will increase. Big brands often take up the top 10 results for high-volume keywords, so if you’re just starting out on the web and going after the same keywords, the uphill battle for ranking can take years of effort.
Traffic is a consequential effect of your SEO efforts. If you were able to improve your search visibility for a high volume keyword, you can almost be sure that your site’s traffic count will also increase. However, a drop in an otherwise steady number of traffic does not always mean that your search visibility took a drop as well. Take a look at this example:
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.
Internal duplicate content is when you have more than one URL address pointing to one and the same page. A great example for such duplicate content is e-commerce websites. Usually, online shops use multiple filters (for price, color, size, etc.) in order to help their users find the right products easily. The problem occurs when this internal duplicate content has not been taken care of properly (noindex tags, canonical tags and robots.txt rules). This can have a devastating effect on your SEO.
Moz Keyword Explorer - Input a keyword in Keyword Explorer and get information like monthly search volume and SERP features (like local packs or featured snippets) that are ranking for that term. The tool extracts accurate search volume data by using live clickstream data. To learn more about how we're producing our keyword data, check out Announcing Keyword Explorer.
3) Google: This is pretty straight forward but it’s the main reason I like it. I search for my main seed keyword in Google, and use the keywords that Google itself highlights in bold on the search results, plus the “Searches related to” section at the bottom to get keyword variations or LSI. That’s basically what Google is telling you that topic is about. No need for a thousands other tools. I use these to optimize the on page of my target pages as well.
You can find broken internal links from within the Search Console. You need to attend to each warning appropriately telling Google that you have fixed it. Having excessive 404s will hurt your site if they are really 404s, because anyone could escalate the 404s by pointing randomly to pages that don't exist from external places, which is why this is not that big of a deal - but should be looked at.
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.
