Welcome to the Q&A Forum

Linking to an image on another site, sometime referred to as inline linking or hotlinking, can be a big no-no for a variety of reasons, including theft of bandwidth usage.

However it is possible that the same entity owns both the first site and the site on which the image is hosted, and they chose to do it that way.

When I demoted a sitelink that was appearing in a general brand search, another (better) one appeared for that search.

However sitelinks are generated depending on what Google thinks will be best for a given search, so your demotion is only a suggestion, anyway.

Actually with Screaming Frog, I can see your H1 tags [www.perfectchaosfilms.com] so it appears not to be a problem with all Wix sites.

I an able to see your different H1s, including "Austin corporate video production company" for the homepage.

Here are the details about PageSpeed insights. A score of 85 or better will get you the green bar.

Note that this is based on network-independent aspects of page performance like server configuration, HTML structure of a page and its use of external resources such as images, JavaScript, and CSS and is not a direct "speed test." [The actual number of seconds will vary based on connection.]

I don't know WIX websites (though from the quick search I did, it does look like you have your work cut out for you) but I took a look at your site with the Screaming Frog SEO spider.
The crawl picks up a total of 14 pages and the H1s are all the same. (There are also secondary H1s that are mostly the same.) It doesn't pick up the images, although of course I can see that there are images.

So I agree with your conclusion that you might have a bit of a struggle. Sorry I couldn't be more helpful--maybe there are some WIX users out there who can share how they overcame these issues.

When I go to your site and search on USB flash drives, I see 53 products, same as in the Google snippet. What number did you expect to see? http://imgur.com/ZKZGvyb

[I know you obscured the domain in your image, but the name of the company is in the title.]

There are reasons for either.

With relative paths (1) you can change your root domain without messing up your structure. (Like moving from a dev environment.)
However, there are arguments to be made for the absolute path (2) including avoiding wholesale scraping and possible domain confusion (http://site.com vs https://site.com vs http://www.site.com vs https://www.site.com).

Check with your developers and see what they say.

Canonicals can be added in Yoast too.

Why do you need 302 redirects? That is a temporary redirect--do you have some pages that have been temporarily moved?

Although many sites do put canonicals on every page (making them canonical to themselves) this is not necessary. You only really need them if you have duplicate content on your site. Do you have that? If not, you don't need canonicals either.

Also keep in mind that a few bad backlinks are not going to hurt you, especially in the context of a lot of good ones. Google knows that these come up.

From Google's Search Console (aka Webmaster Tools) help:

"In most cases, Google can assess which links to trust without additional guidance, so most normal or typical sites will not need to use this [disavow] tool."

There is no duplicate content penalty, as such. (Google "duplicate content penalty" for many articles about this.) When Google comes across duplicate content, it simply decides which version should appear in its index and drops the other one(s). This won't affect the high-quality content you have on other parts of your site.

Here is a good explanation.

And of course DMOZ, if you are talking old-school directory. And the keyword meta tag (not exactly a tool, but it got the job done).

It is not unusual to redirect a whole website and all of its pages, so it wouldn't make sense that you could have too many. And you should keep the redirects indefinitely--what if there is a link to the expired page? You do not want to lose that equity by having it go nowhere...

On a given website, it is better to get links from the higher PA pages (all of the pages will have the same DA).

So a homepage link for example (which will usually have a higher PA than other pages on the site) will be better than a link from a deep, newly created page (which is likely have a low PA).

I like SEMRush. They give a lot of data about both organic and paid search.

It was great to be able to review some of the talks where I couldn't take notes fast enough...

What do you see if you do a search for site:yoursite.com ?

You could noindex, follow the BIGSCHOOL tourism degree page.

There seem to be a lot of members there, and no empty seats. I'll try back.
