The impact of SEM is immediate. SEO takes time. Through paid SEM ads, you can start to put your results in front of audiences with just a few clicks. As soon as you launch a campaign, your ads start showing in SERPs. At any time, you can turn ads on to increase visibility or turn them off to stop showing. Conversely, SEO is something that you acquire over time and typically over a long time. It can take months of implementing an SEO strategy before a brand begins to rank on search engines.
I think the anchor text links in internal navigation is still valuable – but keep it natural. Google needs links to find and help categorise your pages. Don’t underestimate the value of a clever internal link keyword-rich architecture and be sure to understand for instance how many words Google counts in a link, but don’t overdo it. Too many links on a page could be seen as a poor user experience. Avoid lots of hidden links in your template navigation.
There are three types of crawling, all of which provide useful data. Internet-wide crawlers are for large-scale link indexing. It's a complicated and often expensive process but, as with social listening, the goal is for SEO experts, business analysts, and entrepreneurs to be able to map how websites link to one another and extrapolate larger SEO trends and growth opportunities. Crawling tools generally do this with automated bots continuously scanning the web. As is the case with most of these SEO tools, many businesses use internal reporting features in tandem with integrated business intelligence (BI) tools to identify even deeper data insights. Ahrefs and Majestic are the two clear leaders in this type of crawling. They have invested more than a decade's worth of time and resources, compiling and indexing millions and billions, respectively, of crawled domains and pages.
If a PARTICULAR CANONICAL HEAD KEYWORD is IMPORTANT (even perhaps a SYNONYM or LONG TAIL VARIANT) and I think a particular 301 REDIRECT has some positive impact on how Google judges the quality or relevance the page, I will make sure the CANONICAL HEAD KEYWORD and SYNONYMS are on the FINAL PAGE I redirect Google to (which is the one that will be rated and cached).
QUOTE: “We are a health services comparison website…… so you can imagine that for the majority of those pages the content that will be presented in terms of the clinics that will be listed looking fairly similar right and the same I think holds true if you look at it from the location …… we’re conscious that this causes some kind of content duplication so the question is is this type … to worry about? “
The audit is for all pages and not only one. What happens in the majority of the cases is that pages / posts have similarities so you can group them together. For example the pages of a website may be ok but the blog post pages may be missing titles. It’s a lot of work especially for a 500 pages website but you can start from the most important pages first and work your way to the rest
