Unfortunately, Google has stopped delivering a lot of the information about what people are searching for to analytics providers. Google does make some of this data available in their free Webmaster Tools interface (if you haven’t set up an account, this is a very valuable SEO tool both for unearthing search query data and for diagnosing various technical SEO issues).
Description meta tags are important because Google might use them as snippets for your pages. Note that we say "might" because Google may choose to use a relevant section of your page's visible text if it does a good job of matching up with a user's query. Adding description meta tags to each of your pages is always a good practice in case Google cannot find a good selection of text to use in the snippet. The Webmaster Central Blog has informative posts on improving snippets with better description meta tags18 and better snippets for your users19. We also have a handy Help Center article on how to create good titles and snippets20.
Another reason is that if you're using an image as a link, the alt text for that image will be treated similarly to the anchor text of a text link. However, we don't recommend using too many images for links in your site's navigation when text links could serve the same purpose. Lastly, optimizing your image filenames and alt text makes it easier for image search projects like Google Image Search to better understand your images.
Thick & Unique Content – There is no magic number in terms of word count, and if you have a few pages of content on your site with a handful to a couple hundred words you won’t be falling out of Google’s good graces, but in general recent Panda updates in particular favor longer, unique content. If you have a large number (think thousands) of extremely short (50-200 words of content) pages or lots of duplicated content where nothing changes but the page’s title tag and say a line of text, that could get you in trouble. Look at the entirety of your site: are a large percentage of your pages thin, duplicated and low value? If so, try to identify a way to “thicken” those pages, or check your analytics to see how much traffic they’re getting, and simply exclude them (using a noindex meta tag) from search results to keep from having it appear to Google that you’re trying to flood their index with lots of low value pages in an attempt to have them rank.
Keywords research is a very important process for search engine optimization as it can tell you the exact phrases people are using to search on Google. Whenever you write a new blog post, you have to check the most popular keywords, but don’t be obsessed by the search volume. Sometimes, long tail keywords are more valuable, and you can rank for them more easily.
6. Measurement and analysis. You won’t get far in SEO unless you know how to measure your results, interpret those results, and use your analysis to make meaningful changes to your approach. The best tool for the job is still Google Analytics, especially if you’re new to the game. Spend some time experimenting with different metrics and reports, and read up on Analytics knowledge base articles. There’s a deep world to dive into.
Over the last 2 decades, I have unsuccessfully engaged SEO professionals to lift my site on the web, being to scared to attempt anything like that myself (even though as a professional sailor I am comfortable in situations of personal peril during storms at sea). Your guidence and tools have given me the confidence to incorporate my knowledge & expertise into my web site content. I originally doubted my ability thinking professional writers were required BUT just like our guests soak up my wifes knowledge of the underwater world, I look forward rewriting my web site and sharing our specialised knowledge and experience of our “back yard” which is about half the size of Texas !
SEO is not an appropriate strategy for every website, and other Internet marketing strategies can be more effective like paid advertising through pay per click (PPC) campaigns, depending on the site operator's goals. Search engine marketing (SEM), is practice of designing, running, and optimizing search engine ad campaigns. Its difference from SEO is most simply depicted as the difference between paid and unpaid priority ranking in search results. Its purpose regards prominence more so than relevance; website developers should regard SEM with the utmost importance with consideration to PageRank visibility as most navigate to the primary listings of their search. A successful Internet marketing campaign may also depend upon building high quality web pages to engage and persuade, setting up analytics programs to enable site owners to measure results, and improving a site's conversion rate. In November 2015, Google released a full 160 page version of its Search Quality Rating Guidelines to the public, which now shows a shift in their focus towards "usefulness" and mobile search. In recent years the mobile market has exploded, overtaking the use of desktops as shown in by StatCounter in October 2016 where they analysed 2.5 million websites and 51.3% of the pages were loaded by a mobile device . Google has been one of the companies that have utilised the popularity of mobile usage by encouraging websites to use their Google Search Console, the Mobile-Friendly Test, which allows companies to measure up their website to the search engine results and how user-friendly it is.
This topic seems actually quite controversial. Google answered the question by what could be taken as a denial. But their answer was kind of open to interpretations. And on the other hand, there are studies (one of them from Moz) that showed linking out has an impact. So, how can you be so assertive? Is it something that comes out from your own experiments?
